SCW-Greg Just got .30 this morning after holding off for a week.
This .57 upgrade sounds really smart.�
Dec 21, 2013
Mayhemm So, this update is Tesla's response to this?�
Dec 21, 2013
Andrew That's exactly what I was thinking... Wonder if this change was already in the roadmap, or if it's a knee-jerk reaction?�
Dec 21, 2013
lolachampcar I sounds like they went back to the logs on the garage fire car and saw Vin flopping about. If you can see it, you can dial down your current draw and pop up an error message for the owner. NEAT.
This is how the fast response software update should be used. Find it, target it to remove the immediate threat and COMMUNICATE what you have/are doing.�
Dec 21, 2013
yobigd20 So it can detect issues with an electrician's poor or shabby install that have nothing to do with the Model S charging system itself and reduce current to mitigate any possible issue? Definitely neat.�
Dec 21, 2013
Mayhemm Perhaps Tesla have learned from the fiasco surrounding the original 5.8 release? Time will tell.�
Dec 21, 2013
jerry33 Hope springs eternal.�

swegman My update is installing now. I hope it fixes the sleep mode. 5.6 reduced the vampire load. The first version of 5.8 that I received also worked properly. The second version of 5.8 that I installed about 4 days ago broke the sleep function, and I started losing about 8 miles a day again. Am hoping the sleep mode in 5.8.4 will work properly again.�
Dec 21, 2013
brianman Please contact [email�protected] about this if you haven't already. Thanks!�
Dec 22, 2013
loganss After each update you should try toggling the setting that is causing you problems and resetting your main screen. Another member on here discovered that some funkiness happens after an update.�

I am curious about what Tesla considers a "voltage fluctuation" before the software makes an adjustment to the current draw.�
Dec 22, 2013
swegman I did reboot the car without success. But I have not emailed ownership about it. Read that other people had this issue also, so assumed Tesla is aware of it.�
Dec 22, 2013
kseitzberg Perhaps this upgrade changes the charging system so that it again will be possible to charge with the full current/amps when the power is good. I have had the problem after upgrading to 5.6 that power is reduced automatically. I.e. when 32A is available the car only charges at 21/22A. Hopefully the update will allow full power on good installations..�
Dec 22, 2013
OleJA The same happened to me when upgrading to 1.49.22, I think it was. A later update (.24) didn't help, it had to be fixed remotely from Fremont by a FW expert logging into the car.�
Dec 22, 2013
efusco Hard to know objectively, but this seems like the fastest update pushout yet. Seems they're really getting a handle on the process now.�
Dec 22, 2013
PhilBa wow, 4 updates in a month. Seems like it's getting a bit excessive. Especially since I never got 5.6 but went straight from 4.5 to 5.8 (.22). I worry about quick turn updates - fully tested? I've managed software teams a lot and one thing that is a true danger sign is when you hear "hey, I've got a fast fix for xxx problem - it won't affect anything else, completely innocuous. let's push it out."
By the way, I don't think this will prevent a problem with an undersized wire or frozen breaker. It could heat up and start a fire before the current fluctuations cause the car to cut back charging. There's only so much the car can do about the external environment. Note I think the change is a good one - it would probably have caught the faulty UMC problems that we saw earlier.�
Dec 22, 2013
napabill So much for WiFi connected MS's getting the first push of updates. Been connected for 48 hours and nothing.�
Dec 22, 2013
efusco It just started rolling out < 24 hours ago.�
Dec 22, 2013
AmpedRealtor A watched S never updates...�
Dec 22, 2013
Doug_G I get the impression that these fast-turn updates are smaller things, i.e. bug fixes and small quick-turn feature changes (e.g. the fluctuating charging voltage detection).�
Dec 22, 2013
Theshadows That will never happen. The national electric code only allows for 80% of the max circuit draw for a continuous load. Our cars are considered a continuous load since they have the capability to draw max current for more than 3 hours.�
Dec 22, 2013
Mario Kadastik EU is not US. Here the cables rated for 16A are rated for continous load and that's why people are pissed off about reduced charging. My EV bix is rated for 3x32A, but the car draws a max 3x13A, not 3x16A that the single charger should do.�
Dec 22, 2013
napabill Wrong. Was out for a Sunday drive with grandkids and, viola, the clock appeared.
�
Dec 22, 2013
Theshadows Sorry didn't notice it was EU. I agree that it should be location aware. Are you in 50hz? That should be enough to tell the car to adjust the charging rates if that's the frequency you have.�

wcalvin Mine definitely came via wi-fi, as there is no 3G in my subbasement parking slot.�
Dec 23, 2013
VolkerP Yes it could but chances are reduced. If a breaker or a wire heats up to the point where it starts to degrade conductivity, resistance is increasing. This goes along with a voltage drop at the car. If a certain threshold is passed, the car reduces the charging current and issues a warning. It is necessary to have your wiring, panel, breaker, and outlet checked if you see this warning message.�
Dec 23, 2013
jkirkebo No need. The pilot signal signals the car what current it can use. The signalled current should already be restricted by code. In the EU a wall box with a 32A pilot signal needs a 32A circuit. In the US the same box needs a 40A circuit. The car can safely draw 32A in both scenarios.
The problem at hand is that the EU model charger contains 3 separate 16A chargers. So you can use either single phase or three phase. But those 3 sub-chargers are at present restricted to 13A max. So for the time being we have a 9kW/18kW charger, not 11kW/22kW as promised. This restriction was introduced in v5.8 I think, and is supposed to be removed again later on.�
Dec 23, 2013
scaesare Got the firmware prompt yesterday morning, but was pulling out for a 4 day trip, so opted to postpone until I'm not on the road...�
Dec 23, 2013
Blurry_Eyed Installed 5.8.4 last night. These are my initial observations (very limited seat time - about 10 minutes - to make these observations so take them all with a grain of salt.) Rebooted touch screen and dash screen (I always do that after an update as a practice), also toggled the regen and other controls that can be toggled. The below might just be the placebo effect of knowing that the car was just updated again as well but...
* Regen seemed to be stronger than before (in other words it now seems as if regen is the same as it was before the 5.8 update which I felt made regen smoother and less pronounced).
* audio system midbass and bass seems more balanced and volume level has been adjusted. Where as I was running my volume at 6 to 7 before, now running it at 5 to 6 seems to have the same volume level.
* acceleration from standing start seems to be neck snapping like it was previous to 5.8. My impression of 5.8 was that the acceleration had been toned down slightly to be less violent
Those are my quick observations and I can't say for sure if what I experienced was real or just my mind playing tricks on me, but I thought I'd post anyways.�
Dec 23, 2013
Benjamin Brooks I had my 14-50 UMC charge automatically drop from 40A to 30A, on an outlet that I'm confident is robust (installed at a business location with many others).
Worried Tesla's new algorithm in 5.8.4 for dropping charger power might be overly cautious... :/ Wonder what it looks at for the input voltage changes? Droop only or oscillation? Perhaps their hysteresis isn't very good...�
Dec 23, 2013
xhawk101 Oops need override option!�
Dec 23, 2013
AmpedRealtor The car feels snappier... :tongue:�
Dec 23, 2013
Mario Kadastik Well EU cars are in EU and US cars in US so I'd hope that the car knows that if it's drawing from three phase power that it can draw max current�
Dec 23, 2013
mknox Are you confident that the UMC 14-50 Adapter is robust? There have been a number of reported incidents where the adapter to cable interface had failed and/or melted. Might be a good idea to pop the adapter off and check for signs of overheating.�
Dec 23, 2013
Benjamin Brooks That's a good point, I haven't checked the adapter specifically (I believe mine is one of the original versions). I will check it.�
Dec 23, 2013
Benjamin Brooks Other than being warm the UMC 14-50 adapter & contacts looked fine. Called Tesla and they said it looked like the line voltage... which was around 203/204V on a 208V 3 phase outlet, that caused the 25% current reduction. Thinking this is going to become a big issue for people on 5.8.4�
Dec 23, 2013
Zythryn Mine is charging on a 14-50 at 40 Amps as we speak (on 5.8.4).�
Dec 23, 2013
Jason S I haven't checked audio since the upgrade last night, but I'll try again tonight. I'd thought +4, 0, -1 with +12 to the rear was pretty good with the previous version using the original upgraded sound.�
Dec 23, 2013
mknox Indeed. I regularly see voltages in that range, and sometimes even lower, on public 208 volt systems.�
Dec 23, 2013
doctrewho I received this update last night. I have been charging my car at only 30A since delivery last month as well.�
Dec 23, 2013
dbanner Downloaded the software this morning and the amps on both outlets at home and work were cut down to 30. Perhaps this is an overreaction. Where is that opt out button when you need it?�
Dec 23, 2013
Theshadows Ours has been 40amps every time I have checked since the update. Lowest voltage I have seen is 234 and it was still at 40Amps.
It would be nice to see what the variance is to see if the current reduction is due to voltage or something else.�
Dec 23, 2013
Lump I lowered the amps down to 30 a month ago & just installed the update, I'm glad the car will monitor & take action if it senses fluctuations.�
Dec 23, 2013
dsmith2189 Just got the upgrade today. after the upgrade my Radio was off. First I tried to change the volume with no results. mute/unmute didin't work. I had to manually go back into the audio selections and reselect my FM station to hear the sound. From this and earlier posts, it looks like they did some audio system tweaking in this revision.�
Dec 23, 2013
Panacea Just started remote charging after the software update...charging limited to 30 amps now.
____________________________________________________________________________
Update: Started charging the car while in the car and that is when I noticed that after the update, the amps were set to 30. I increased it back to 40 and charged at 40 no problem. My bad, lol..�
Dec 23, 2013
Bugeater Ok, got this update Sunday morning. Strange thing was that we got in the car the main screen wouldn't come on! I tried a few times to reboot it as I was driving and it finally rebooted. Can't blame the new firmware because it wasn't installed yet! I was on the latest like most everyone else.
Noticed soon that my average wh seemed finally back to normal. We've been averaging over 400 since 5.8! Now it is back to just over 300. So I tried to take a screen shot but that doesn't seem to work any more! Pressing and holding both lower steering wheel buttons no longer will provide a screen shot. I held it for at least half a minute once. Has anyone else noticed this in recent updates? It's been a while since I had tried this.
Then today I'm noticing that Slacker Radio suddenly is very unreliable. It has always been good for me before. Songs skipped, dropped and restarted, paused for a long time...
Here's a camera shot of the change in power usage.
Note that I just caught the tail end of the previous higher usage due to playing with the screen shot issue..�
Dec 23, 2013
Doug_G My car is currently charging at 234V, 40A on a UMC. No sign of it pulling back the power.
Our office charger only sources about 200V at 70A, since the source voltage is only 208V from 3-phase. I'll check and see if that causes it to pull back on the power. If it pulls back current on lower voltage, not "voltage fluctuations" as claimed, then it's going to be a big problem on road trips. Most of the 70A stations I have encountered are on 3-phase sources and are around 200V.
Edit: actually I think this may be a real concern. A fellow from Montreal stopped by for power today, and when he quickly checked his app the car was NOT drawing full power. I assumed it was still warming up, but maybe it was actually pulled back.�
Dec 24, 2013
Mayhemm This actually might be a deal-breaker for me if it proves to be an issue.
I'm already going to spend huge amounts of time charging when on road trips and have accepted this fact. However, that doesn't mean I want any more delays.
Well, Tesla, you've got about 2 months to fix this or I may have to delay ordering.
I'm confident in your ability, but I hope this doesn't get missed in the rush to fix the air suspension controls.�
Dec 24, 2013
Theshadows I wonder if the charging reduction applies to J1772 stations? Has anyone seen a reduction since updating?�
Dec 24, 2013
patp Good point. I'm anxious to know the answer.�
Dec 24, 2013
loganss Looks like I'll be holding off on this update too. I'm on the 5.8 .2X variant.�
Dec 24, 2013
Doug_G I'll do a test in a couple of hours. However, I suspect the answer is "yes", because the car can't tell the difference between a J1772 and a UMC. They use the same protocol.�
Dec 24, 2013
mknox If it bumps the rate down, can you bump it back up from the touchscreen? If so, will it stay back up at the higher setting?
I think Tesla may need to tweak this so that it only throttles if the voltage is actually fluctuating which would be more common with a loose connection.�
Dec 24, 2013
Doug_G I don't think so.
The release notes said "fluctuations". We'll see if that's what really happens.�
Dec 24, 2013
KOL2000 I charged at the Zoo the day after the update on a blink charger and there was no difference (15/mph).�
Dec 24, 2013
100thMonkey I have .4 and last night, for the fun of it, I plugged into the chargepoint at the PCC in Edmonds WA, using the J1772 adapter. the car attempted to run up to 40A and then shot down to 7A with an alert popping up on the dash to the effect of: either you have plugged into an extension cord or there is faulty wiring. I called Chargepoint and let them know there may be a problem with their plug or Tesla's latest software iteration has resulted in the car being hyper sensitive. the J1772 plug is a bit on the old and worn side so chargepoint is likely going to replace it. I also contacted Tesla after hours and reported the issue. The Tesla guy I talked to by phone said there have been several such reports on various home and public chargers and it's being looked into. I would hope this new update is revealing real issues and not causing unnecessary reductions in charging speed. If these are real, then "yay" lets get the wiring/plugs brought up to par!�
Dec 24, 2013
gg_got_a_tesla Have had the update notification for a couple of days now but, will hold off updating as I'm on the road. Guinea pig experiments when back at home base.�
Dec 24, 2013
steve841 I have a Chargepoint Station and that's my primary charging source .... no issues with the new software.�
Dec 24, 2013
Sunfishsolar.ca Got the update. Plugged in at home 15/50 plug (stove) always set it at 40 amps, looked and it was charging at 30 amps. Brand new wiring and plug. I do have solar on my roof and my daily voltage goes from 239-264 depending on sunshine/grid/charging. I trust they will get this worked out. I need to know when I plan a charge for morning it hasn't backed off to 30 amps. I'd rather have my breaker pop then not be full for trips away. Ps I jumped into the car and turned it back up to 40 amps and it stayed there for the rest of the charge. No warnings in the car.�
Dec 24, 2013
Panacea That is what I suspect as well. At first I charged from my app and could only get 30. When I went into the car I saw that it was set at 30. Increased it to 40 and it happily charged away. But I am thinking of putting a dual sensor smoke alarm in the garage just in case.�
Dec 24, 2013
Doug_G Okay, I have good news. As you can see, I'm getting only 197V, but the car did NOT back off the charging current. So having low voltage alone doesn't trigger it.
�
Dec 24, 2013
Theshadows The solar won't effect it. Solar actually raises your voltage by a hair.
The wire that they used to run the circuit could be too small. If voltage drop calcs were not done that could be causing it. If you let me know how long your wire run is I can let you know if it's the right size wire.�
Dec 24, 2013
ecarfan 100thMonkey, just to be clear: can the car detect if an extension cord is being used, even a good quality cord properly designed for the amperage being pulled? Or is that warning designed to alert the owner that there is higher than normal resistance in the charging circuit and a possible explanation is a poor quality extension cord?�
Dec 24, 2013
jerry33 No, it can't tell that.�
Dec 24, 2013
100thMonkey resistance and or fluctuation, I believe.�
Dec 24, 2013
Theshadows The car would be able to tell if the wires are heating up or are of inadequate size because as they hear up the voltage will drop and continue dropping. It could then be programmed to display this message.
For the 15-50 circuits if the circuit length is 50ft or less #8 copper will work. Longer than this requires #6 up to 150'. I didn't look at longer lengths because I felt longer than 150 would not be that common.
Because of what the circuit is being used for and the high frequency of use I opted for the larger wire size so we are not using electricity to heat the wires. I ran #6 for mine despite my mains panel being 6' from our 15-50 outlet.
Something else you will want to watch for if you have a detached garage or your outlet is being fed from a sub panel is that the wire size between the main panel and the sub is adequate.
Faulty circuit breakers can also lead to fluctuations that would cause the charge rate to be reduced.
I think we are going to see a lot of J1772 chargers that will have reduced charge rates because of cheap installation work and inadequate wire sizing.
Either way it sucks to have a reduced charging rate but at the same time it's going to force the quality of the outlets we use to be held to higher standards.
I suspect we will see reduced rates at campgrounds too. In our area a lot of campgrounds installed electric 30-40 years ago, and it was Jim & Bob from down the road that weren't afraid of electricity that did the work and didn't have to pull a permit or just plain ignored it.�
Dec 24, 2013
jerry33 I always reduce the current a bit at RV parks. Most can't really do 40 amps. Just a few amps lower doesn't really take that much longer and saves you from going to a different spot.�
Dec 24, 2013
scaesare I'm in the same boat... charging/functionality surprises, or worse yet a bricked car(not that such things are common) while hundreds of miles from home are no fun...�
Dec 24, 2013
Eggplant One thing I've noticed in the 5.x series...
As of 5.6, super chargers were no longer added to my visited chargers list. I had one SC I visited under 4.5 listed, but a new one I visited days after upgrading to 5.6 wasn't added.
As of 5.8.4, the one SC I did have listed on my visited list was removed. Now SC locations are only seen on the SC list and no longer show up on your visited chargers list at all.
No big deal really, but it was fun collecting them.�
Dec 24, 2013
Mayhemm Seems like something a screen reboot would probably fix...�
Dec 24, 2013
apacheguy When are we going to get the option to remove visited chargers?�
Dec 24, 2013
fmda That would be nice if it can be done for each specific. I have one on the middle of the highway that i would like to remove. . I think a gps error�
Dec 25, 2013
montgom626 I used #6 wire on a 6 foot run. Good idea.�
Dec 25, 2013
Eggplant Nothing to fix... Just a confirmed change in behavior I've not seen mentioned yet.
I agree! I put in a feature request a long time ago for this. I have several locations duplicated with the same address. I presume because the GPS coords were different enough for Tesla to list them twice, but the reverse geocoding comes up with the same address. Being able to delete them like you can on the recent nav screen would be ideal.�
Dec 25, 2013
SteveH +1000
It really creeps me out that there's a loaner car out there with a red dot showing where my house is.�
Dec 25, 2013
scaesare Well, I got back from my road trip tonight and installed the upgrade.
After it finished I started a charging session just to see if I saw any charge-current reduction as others have reported. The car reported my line voltage as ~245 volts with no load. Once it ramped up to 40 amps, my voltage drops to about 235, but doesn't fluctuate significantly. This is about normal for my house. The car continued charging at 40A without issue.�
Dec 26, 2013
bob_p After driving my first loaner, I reported this problem to Ownership. Other cars typically have a "clear personal data" command in the user interface - not available (yet) with the Model S. Ownership indicated the Service Centers can clear this data on the loaners - so if you see one that hasn't been cleared when you get it - when you bring the loaner back to the Service Center - ask them to clear the data, if you don't want your home location to show up on the charging station list for subsequent drivers.
Hopefully this is on Tesla's "to do" list for the software...�
Dec 26, 2013
patp What they should do is transfer your profile in the loaner so the car feels like your car. Then, they erase it when you return the car.�
Dec 26, 2013
Najeeb Perfect solution. All your radio stations, seat and mirror positions, GPS history, regen, etc would be very nice to have transferred over.�
Dec 26, 2013
digitaltim Roaming profiles attached to our TM online account - sounds perfect!!!�
Dec 26, 2013
AnOutsider That's a good solution, otherwise it might be a month manual process linking up cars.
In any case, I can't see it being a priority since this should really be something that is rarely necessary. Few families have multiple teslas and you shouldn't need to be in a loaner so often that it becomes a big annoyance.�
Dec 26, 2013
dflye So after applying this update a few days ago, I have had problems where the "deep sleep" mode is so deep the touchscreen never wakes up, where it is ignoring the display energy saving preference and putting the car to sleep less than a minute after the fob moves away from the car (even with the driver's door open!)
Took it by service on the way home from driving around this morning, where I was making many short stops. Eventually gave up on rebooting the touchscreen, as it was becoming unresponsive within mere minutes even after a reboot, and was going into deep sleep extremely rapidly regardless of energy saving preference.
The final straw was when the instrument cluster display refused to wake from sleep (thankfully on my last stop of the morning.) While I'd already gotten used to having to wait for the instrument cluster to allow me to put the car in gear, it was a bit more of a pain driving with both touchscreen and instrument cluster displays dark! The behavior of time from entering the car to being able to shift into drive remained the same (about 15-30 seconds), but was a bit disconcerting to drive the 20+ miles with two dark screens from where I was to the service center (which thankfully is only a few miles from home)
At the Raleigh service center, they confirmed this wasn't something they'd seen or heard of, so hopefully it is just something specific to my older touchscreen not fully accepting the update, rather than an indication of some broader issue. While using the steering wheel controls to reboot both displays temporarily resolved the issue, the touchscreen still locked up within minutes, so at least the service center has direct experience with the issue and doesn't think I'm merely a raving lunatic. :wink:�
Dec 26, 2013
Zythryn Sorry to hear that dflye.
No such issue for us with an older touchscreen (VIN 116).
Hopefully it is a unique issue and they can quickly resolve it.�
Dec 26, 2013
dflye Since the car is drivable enough as far as I'm concerned and they had a queue of other cars to work on, the service manager and I decided that I'll keep driving the car around until they can get someone from the engineering side in CA in the next few days to troubleshoot before they jump straight away into something like a touchscreen replacement.�
Dec 26, 2013
Bugeater Dflye, I had something like this happen to our MS (vin 2201). It doeant go to sleep that quickly, but the touch screen didn't power on once! It took several attempts to get it to reboot but it finally did. This was right when the 5.8.4 update was ready to install...�
Dec 26, 2013
dave I had problems sleeping and waking up after 5.6 came out. They ended up having to replace my instrument panel. This also wiped out all my settings and energy history, etc, which makes me think they don't have the ability to transfer profiles either.�
Dec 26, 2013
ckessel I had my center console replaced and lost all setting as well. They told me the information wasn't, at that time, transferable.�
Dec 26, 2013
Mayhemm Interesting that the settings/history are wiped when replacing the instrument cluster OR the touchscreen. You'd think the data would only be stored wherever the internal hard drive is...�
Dec 26, 2013
brianman This won't work for me for cars without Slacker. For others, it won't work if they use XM. Etc.�
Dec 26, 2013
Doug_G I also had my touchscreen replaced last February, and can confirm that I lost all settings, saved chargers, trip odometers, etc. when they did that.
Maybe they have to do a full "system restore" when changing one of the two components.�
Dec 26, 2013
AEdennis I have requested this from a loaner I used. They supposedly did it. However, my house showed up with all the stuff remembered from the last time that I had the same loaner.�
Dec 27, 2013
Andrew We had our center screen replaced a few weeks ago (they were troubleshooting a problem in the audio system, and decided proactively just to replace the screen). They managed to transfer some settings, including our Homelink programming (yay!). My husband's profile transferred fine, but mine didn't - it came through as a profile with a blank name, and it didn't keep my settings. Deleting it and recreating a new one kept the same problem - but once I rebooted all was right in the world.
So it seems they can transfer SOME settings when swapping out the screen.�
Dec 27, 2013
bob_p Shouldn't be too difficult for Tesla to upload the car's settings & profiles to owner's accounts on their servers - and then provide in the loaners the ability to "log in" and download those settings.
Tesla should seriously consider at least a short term "surge" of software resources to implement features like this - and the missing features in their onboard software (navigation, entertainment, smartphone integration, ...).�
Dec 27, 2013
ElectricRed Does anyone know if 5.8.4 will give you a history of when it had to reduce the charging current? It'd be beneficial to know that reduction happened so I can get the wiring checked if necessary.�
Dec 27, 2013
dbw77 Since updating somewhere between the 5.8 ".30" and the 5.8.4, the Energy Saver (Sleep) mode, which, for the last 3 months has worked perfectly, stopped working. Seems the car now never goes to sleep and is loosing range/SOC very fast. Nothing else has changed, and I have tired all the usual stuff, togging the ON/Off on the new energy saver setting, rebooting etc.
Has anyone has similar experiences? I have an email into ownership, but no news yet.
Thanks!�

Zextraterrestrial Try using visible Tesla. I just started using it a couple of days ago and saw when my charge dropped 40A to 30A last night.�

swegman My sleep mode is not functioning correctly since the 5.8 update. I was losing 2-3 miles per day with version 5.6. Now I am back to losing about 8-10 miles per day. I have not reported it to Tesla.
Update: Telephoned Tesla to report this issue. Was told the issue will b e passed on to the engineers.�

AnOutsider Not sure if its related to the update, but I woke up early this morning and, remembering we were going to be driving a lot today, I popped into the app to get the car charging in range mode. I kept hitting "start charging" and nothing happened. Then I noticed my SOC was 213 miles and realized it had stopped charging before full (I go to 230-235).
Head downstairs and sure enough there's a red ring on the charge port. Dash reported error charging call tesla and another error saying error charging unplug and try again,
Unplugged and put the cable back in and all seems well, but the last time this happened I ended up needing a new battery :/�

AmpedRealtor Doesn't using VisibleTesla to monitor your car prevent the car from going to sleep?�

Oyvind.H This is how the Tesla UMC works i Norway. In other words - seemingly noone in Norway can restart charging from the app when using Tesla UMC. Scheduled charge doesn`t work either.
But this is related to crappy european UMC, not firmware though.�

dbw77 Got a call from Tesla yesterday stating that the field support techs had reset something in my car, after looking at the data they had, and now the sleep mode is working as expected.�
Dec 28, 2013
Mario Kadastik I think in Norway it's your bizarre power system that is odd in comparison to rest of Europe. My UMC has worked flawlessly for scheduled charging when I used it.�

mknox I have found this too, but also discovered a workaround. Turn on your HVAC from the app first, then start the charge cycle. Once charging has started, you can turn off the HVAC. This has been working for me.�

tezco I like to charge mid-day when my PV system is providing carbon-free electricity, but sleep mode seems to place the S in a deep slumber from which it can't awaken. If I open the door charging starts, but if I'm not home it's a bit of a pain to remember to call up the car. Glad I'm not away on a long vacation with the battery drifting lower and lower....�

Doug_G Here's a minor glitch I encountered today. The media controls on the steering wheel would not operate. You could change modes on the left side console screen, but you couldn't pause, forward, etc. Rebooting the touchscreen fixed it.�
Dec 29, 2013
AnOutsider Well what's odd is that it stopped charging before full during the night, so don't think it was solely that�

kendallpb Yuck! Sorry to hear that - hope they can resolve this quickly. I'm not surprised they want their engineers to look into it a bit, but sometimes they seem to replace the main screen pretty quickly for other folks, so I hope they don't take long to decide/figure out...that sounds like a very frustrating problem.�

napabill Made my annual trek from Napa to Tucson over the past couple of days. Have updated to .57 firmware. At the Shadow Hills RV Resort in Indio, CA, I had reserved a 14-50 spot for the night. When I plugged in got the warning message and couldn't get more than 30 amps. It was only showing 199v which I suspect is the problem. But it was a nasty surprise as I couldn't do a range charge. When I arrived at our place in Tucson and plugged into my 14-30 plug, that I used all of last season at 30 amps, would now only allow me 24 amps. No warning this time, just locked the amp slider. I'm thinking this firmware update may be a bit of an overreaction. Hopefully TM will modify the firmware to be a little less severe.�

mitch672 napabill, 24A is the maximum allowed on a 30A dryer circuit, that's normal. It's always %20 less than the rated amperage because of the continuous load rules.�
Dec 29, 2013
gg_got_a_tesla Right, I'm limited to 24A from my 14-30 outlet at home as it should be. This had been the case pre-5.8.x as well.�
Dec 29, 2013
Mayhemm I think Bill's real issue is that he could only get 30A from the 50A outlet at the hotel (which should allow 40A). I agree that the performance of the 30A outlet is normal.
If Tesla doesn't do some serious tweaking, it sounds like the power-limiting function could end up being a serious headache when road-tripping. I can't see many proprietors responding with "Your car says my wiring is bad? I'll get right on that!". The realistic result is travelers will just see a 25% reduction in charge rate at many sites. Not something I would tolerate for long. IMHO, this should be prioritized over even the air suspension fix as it has much greater real-world consequences.�

napabill The lady that showed men to my $60 14-50 plug and space was astounded that Tess had an issue with there wiring. She claimed they regularly have an electrician inspect the circuits. Who knows, but I can say most of the occupants there spent an amount equal to or greater than what we paid for the Tesla. Admittedly, once a SC is installed in Cabzon/Indio, RV parks will be in my past.�

zax123 My anecdote:
I often charge on a 6-50 at 40amps at my mom's who has a welding plug in her garage. I use a 30+ foot extension cord from the 6-50, and then plug in the UMC. Until 5.8.4, I was getting 40amps and 240V no problem. When I plugged in on Xmas day, it dropped down to 30A... I doubt there were "fluctuations" in the power feed, I'm guessing it somehow detects the resistance formed by the extra long extension?
In any case, it's a bummer. Losing that 10 or 12 km/h in charge rate hurts a bit. I didn't try to manually bump it back up to 40A. I was inside and it was REALLY cold that day. Would be nice to be able to adjust charging amperage from the remote app (or Visible Tesla)...�

qwk Tesla needs to take responsibility for their underengineered adapter end of the UMC. Lowering charging 25% when somebody paid for the full 40A is not too cool.�
Dec 29, 2013
jcaspar What gauge is your extension cord? 6/4 SOOW?
�
Dec 30, 2013
mknox Yeah, I have found that too. I have also found the car will sometimes charge in fits and starts as opposed to continuous current.�
Dec 30, 2013
Theshadows 199 volts is too low. They probably used the 3% rule. So anything less than 201v on a 208v circuit and 232v on a 240v circuit will get you a derated charge.�
