I am manually changing the reserve based on time of day. I plan to automate it once I get a better understanding. Also waiting for new utility rate feature with multiple peaks to roll out to see if it will match what I want to do. Time-based control is not working correctly since recent...

Self-Powered with reserve set to 100% is not equivalent to old Backup mode. One difference I have noticed is that if I change the reserve back to 100%, the batteries are not getting 100% of solar production sometimes. I am not sure if Tesla has some forecast in terms of how much solar production...

I noticed that the green light in the app is the SOC battery level, and it decreases as battery energy is depleted. So it does serve some purpose, and I haven't confirmed this but I think the light on the powerwall does not indicate the battery level as it does in the new app.

I was able to use the key card to unlock or lock from the driver door. You have about a minute to push the break pedal to drive the car before you need to unlock again.

Tesla has documented the utility rate plan on their website: Utility Rate Plans | Tesla Support From the pictures, it seems that it will be possible to edit them in the app. It also mentions that this requires Powerwall firmware 21.39.

Tesla added instructions on their website on how to setup this new rate utility plan: Utility Rate Plans | Tesla Support. I still don't see the 'Utility Rate Plan' under Settings on my app though. Probably this will be rolled out soon.

I just got 4.2.0 app on iOS. It says Powerwall Time-Based Control supports multiple peaks. I could not configure more than one though. Gateway is on 2021.35.0.

I have version 21.35.0 since Oct 1, and so far here are my observations: 1) I don't see the trickle charges anymore. They used to show as blue spikes (grid) in powerwall graph. 2) Battery degradation as seen in total_pack_enegery API field is now back. With 21.31.0, the degradation stopped...

Do you have PW2 with Gateway 1? I also had a total pack energy bump when I got upgraded to 21.31.0. From 11,416 kWh to 11,539 kWh. The degradation also stalled compared to before. I used to see this number go down almost every day.

Darn. I am still waiting for an update as well but I am on Gateway 1. I had a service request through the app, but I never heard back from Tesla, and the ticket is gone and I cannot see it anymore in the app. Not sure why they have added service requests in the app if it cannot be reliable...

Good point, doing this now for good measure. The app was not showing same day backup history when storm Ida was passing through our area. And it was not possible to refresh the backup history. So hopefully this trick of deleting app and reinstalling it would fix those issues. The functionality...

I noticed that the app does not show data at times (zero flat lines), but if you pull down on the graph it triggers a refresh, and the data is then updated.

Thanks for the heads-up. I will keep an eye for this update. I had created a service ticket using the app 1 week ago, and so far I haven't heard back from them. I thought I would give this method of requesting support a try since I didn't think my issue was urgent, and I didn't want to wait...

In my case, the module was not responding to any phone or key card registered with the car. The only way I was able to start the car was using the key card with the external reader by the driver door. Anyway, I was able to get the module replaced in my second attempt. I made sure not to install...

There was a software update being pushed at the time, so I changed the setting to get the update earlier (advanced). This is a link that describes this: Software Updates Tesla did not replace the module after it failed and I installed the software. You might want to schedule a service and have...

Go Off-Grid is now showing on my Tesla app (initially it was not there. It shows under Settings). I haven’t tried it yet, but it requires pairing Powerwall with phone first. Documentation online says this feature could be useful to simulate power outages without disconnecting main panel.

The oversight is specific to the charging behavior. Back in May 2019, I was experimenting with using Powerwalls for backup only but keeping the SOC at less than 100%. I used Time of Use and set peak time to coincide with solar production, so in effect battery stayed at the reserve level. I...

Since the post on new app has been moved to another post, the reason I posted on new app initially was because it revealed that Tesla has removed Backup-only mode as a powerwall setting, and it is now replaced with Self-Powered with 100% reserve. Tesla support website also reflects this change...

Same here. It is harder to see the numbers now, and from what it seems, there is no way to overlay the graphs from different sources.

Tesla app v4.0.0 has been released, and one of the changes is there is no backup only mode anymore. I had my PW on backup only and now in new app version it shows it as self powered with 100% reserve. So my guess is that the new Powerwall gateway version removed backup only mode and now this new...

I am still in Storm Watch, but it also seems to have changed behavior and now trickle charging to keep it at 100%. Not sure if this is temporary after software upgrade while battery re-calibrates or it will be a permanent change.

This morning, my powerwall gateway was upgraded to v21.31.0, in the middle of a Storm Watch (Hurricane Henri)!

I rescheduled a service appointment for my car, and this time made sure not to install the software before the service appointment. After tesla service confirmed that the module was not working correctly, they replaced it with a new one. So hopefully this is the end of it :) The cost was covered...

I tried changing the wheels, and the MCU was rebooted, but still NFC reader is still not connecting to my phone. The reboot from changing the wheel configuration seems similar reboot as when pushing the two scroll buttons on the wheel. Tesla FAQ says you can power off the car in two ways...

100% SoC is mainly a concern for those who leave the powerwall in Backup-Only. This mode is used when utility doesn't have peak and off-peak rates, and therefore there is no incentive to use the battery on a daily basis, and 100% of the energy is preserved for power outages. So there is no ROI...

I left it this morning for 1.5 hours after Power Off from touchscreen and without phone access, and still NFC reader is not getting reset. I wish there was a way to do a deep reset similar to a software update, because that fixed the issue last time.

Since the Tesla software update fixed the phone key issue last time, it is back shy of two months. @jjrandorin , I tried Power Off with door open, and it didn't make a difference. I don't think the Power Off does anything but turn off the car the same way if you exit the car and close the door...

I stumbled on this thread because I wanted to find out if there is a difference between Backup-only mode versus 100% self-powered mode. My observations for Backup-Only mode is that the battery is charged from solar when it dips below 97.0%, and it will charge it up to 99.0%. And for 100%...

So I went to service center today and spent about a total of two hours in driving, to be told that there is nothing wrong. I guess next time this issue happens again, I will avoid a software update, and wait for the appointment.

I also tried power off but sitting in the car, and only waited 2 minutes, because it felt like forever. I will keep these instructions in mind for next time I need to do this. Thanks.

Makes sense. The software installation might have done something more than the reboot I did with the two buttons and brake pedal. I will try to find out from the tech at service center if I would have been able to reset it in another way.

I had 2021.4.15.10 before. The new version I got is 2021.4.18.

My 2 year model 3 suddenly lost recognition of my phone as a key as well as my card key. I no longer was able to start the car with phone, nor by tapping the key card behind cup holder. My wife's phone and key card also had same issue. The phone was still unlocking and locking the car. I tried...

I have it in Backup mode, so reserve is 100%. But Powerwall has different algorithm when demand response is active, and the reserve for that event is not exposed in app. Once the event is over, Powerwall reverts back to the mode set in the app.

I signed up with Tesla. I think someone on this forum tried to sign up directly by submitting an application to Eversource, but Eversource sent it to Tesla.

I have given Connectedsolutions a try last year, and it was total failure. I had to opt out of the program before the end of the summer season. The program claims that they do not use the batteries during severe weather conditions, but 2 times, my batteries were draining during a Storm Watch. I...

It might be better not to participate until they improve the program. Part of the contract could make you ineligible to subscribe in the future if you withdraw from the program. I replaced the email address from contract with XXX. 9. Customer Termination: Once You are accepted as a participant...

I totally agree with you @wjgjr. I do believe that this program is important a a whole. Right now, there are some serious flaws that need to be addressed seriously before it is sold to customers. There are people I know who are looking at buying Solar + storage from Tesla, and Tesla website...

Part of the agreement for demand response is that no discharge occurs if there is any extreme weather such as what we had yesterday. But the way this has been implemented has turned me into one unhappy customer, and I have sent an email to unenroll from this program entirely, and forgo any...

Yeah, this goes back to the scenario I discovered in last outage. If a power outage occurs, and the batteries are off, the gateway would loose power I think and I wouldn't be able to start it up. I only need to wait until 7pm, so another 35min, and then the event is over and will be able to...

That's what I ended up doing, I flipped the main breaker when my battery reached 50%. I guess A/C is now a secondary concern :)

There is a severe thunderstorm warning in my area, and it just reached us. But the Powerwall is not in Storm Watch mode. I am talking to a second person at Tesla and she is escalating it to Tier 2 and trying to get someone to stop this event. I am definitely not going to go through this again...

One of the unfortunate discoveries is that if I shut down the gateway during an outage, the power is not restored after I bring the system back up. So if I shut down the gateway and power goes out, I am not sure if it will start powering the house.

I might do that if I get no where. I already hang up with the first Tesla customer service who had no clue what Grid Services is about. Wasted about 30 minutes. His recommendation was to switch to Self Powered mode for 10minutes and then to Backup mode. I have A/C that it is not connected to...

I am on the phone with Tesla because even though there is a Severe Storm in our area, and people are loosing power already, my Powerwalls are draining at 6.8 kW and is at 73%. I have no way to stop it. And Tesla customer service doesn't seem to have an idea what to do. I am most likely going to...

You can contact Tesla at [email protected]

Eversource NH has Tesla listed. https://www.eversource.com/content/nh/residential/save-money-energy/manage-energy-costs-usage/demand-response/battery-storage-demand-response

We also got power outage for 5 days. If the storm is known ahead of time like the one we got from TS Isais, Storm Watch is enabled, and no discharge occurs. On Aug 4, we lost power around 2PM, so the event had not started yet. But before that, there were two Storm Watches during the event, and...

Out of curiosity, how much power does this ground-source heat pump use when it is running? Is it the same whether it is heating or cooling?

Did you get the paperwork from Tesla or did you do it directly with Eversource? My contract with Tesla says this about payment: "Your Powerwall’s performance will be calculated by your utility at the end of each season (Summer and Winter). Tesla will collect money from your utility and pay you...
