Charge By Solar Not Showing

[h2ofun]

Rebooted my model 3 computer (again) and now have both sliders in the charge screen in the phone app (for only the model 3). So apparently after the firmware updates, you need to wait for CoS to appear in the phone app and then reboot the car computer to get everything enabled.

I did not have to reboot my car to have it "work".

Rebooted model Y and it's working in that one now too. It was a cloudy day and Powerwall didn't quite make it to 100% before peak rates at 4pm. I got the notice in the app that "charge on solar paused for Powerwall priority". At 4pm, all solar is being exported to grid and Powerwall is powering the house. So far, things are working the way I'd hoped.

I need it to work having my Powerwalls charged first to the level I want, which for me would be 100%

I don't see any explicit options to choose a priority so assume it's just based on Powerwall mode and however you have your tou rate structure set. I have sell price set to 3c less than buy to approximate the NBC losses.

I did ask if my gateways could be updated to .11

I can confirm I am on .11

I am on .10

And I have multiple Powerwalls (not as many as h20fun) but only 1 gateway.

I logged out and back in, and the solar option came back up

Thanks. It never showed up in my app until I signed out and back in.

Just on the phone with tesla PW support and she told me she has never heard let alone seen an option for the powerwall setting before car charge.
Does anyone else have the option, and how did you get to show?

Never had an option for powerwall priority in the Tesla app. Just saw the two messages indicating that either PW was prioritized, or CoS was paused for PW.

ChargeHQ (3rd party, for pay app) does have the ability to select a priority of either EV or ESS (PW) for excess solar. But it doesn’t have the option to have a any source charge limit daily followed by a solar excess limit.

You can set an Always Charge schedule in ChargeHQ to maintain a set limit regardless of excess solar.

I now have CoS on my 3 and Y as of today. I can configure it in the Android app but both cars charged to the upper limit this evening from grid. Neither in car charge screen indicates the CoS settings so perhaps I need to wait another day before it's fully active.

 

[Kerbonaut]

I got it in the app first but I had to reset my Y computer for it to show up in the car. Once I did that, I had the CoS option both places for ~3hr. Now, however, if I disable CoS in the app, the menu disappears entirely until I reactivate it in the car. Am I just missing something? CoS settings (when visible in the app at all) now appear under the "Schedule" menu in the app.
PW: 23.12.10
Car: 2023.26.6
App: 4.23.6-1844

IMO,nothing you would want to use yet

I think in my circumstances it will be possibly beneficial. Home a lot in day, have free power 9p-9a but no net metering which works with pw grid charging enabled. usual use is zero grid 9a-9p. The principle of not giving away free solar power in day is what i am looking for.

 

[h2ofun]

I have received two types of messages indicating powerwall priority…

I’m also using ChargeHQ now too, so unsure if that’s what is prioritizing the PW. But clearly that wouldn’t create either of the messages below.

For those people just getting the FW on their cars, it seems you need to wait ~24hrs after the install for it to appear in the app. It seems to do something with a “key” and then you confirm your home address and there appears to be a handshake with the powerwall.

Lastly, it appears the settings for CoS moved into the … menu. Only when I click that can I now set the CoS limits.

Hoping they add support for multiple cars soon!

what is your gateway version?

I just have my car plugged in, watch my PW charge level, and when 100%, just hit charge car in the app.

what is your gateway version?

23.12.11. But as said earlier, there’s nothing in settings about prioritizing powerwall, just the two messages. The only thing with something settable is ChargeHQ app.

Is having a PowerWall+ or newer a requirement for this functionality. I am interested in this feature, but don't see it anywhere in the app or the cars. How does the system know a car is plugged in to the WallConnector?

M3 #1 at 2023.7.20
M3 #2 at 2023.12.11
PW (gateway) at 23.12.11

So, looks like I might have misread the post. So those last two screen shots are NOT Cos, but ChargeHQ? Was not clear to me. Opps

The cars need to be on at least 2023.26.x. Your gateway version is already good to go. Non "+" PW work too. Once the cars have the proper FW, it knows where it's charging. It knows it's associated with an account that is also associated with a PW. There is an explicit pairing process as well ... presumably for accounts with multiple gateways or multiple PW enabled locations.
