Please remove Tesla powerwall from the HA integration. No longer works. It’s a waste of time trying to get it work. This should be a big red banner.
It is still working perfectly fine for local access to my Powerwall 2.
And the HA devs can be a long time removing non-working core integrations.
I have reported the Rejseplanen when it shut down its API and became nonfunct and have kept reporting it for several years now, so dont expect any actions on such things.
Outdated and not the future (pw3, pw4, etc) . It should be deprecated at best.
Posting it here is like hollering into the dark.
The only place to report this stuff is: home-assistant · Discussions · GitHub
In general, these gauntlets are picked up by volunteers, so if you want to fix it, go up there and fish around a bit and ask what you can do to help.
Please do NOT remove Tesla powerwall from Integration
My setup works fine and a lot of my automations depend on it.
It doesn’t work at all.
If you call Tesla support you’ll find out the same thing. If you look at github you’ll find out the same thing. Powerwall 3 needs to be removed from the integration completely it doesn’t work, it can’t work. It’s not even a limitation. The powerwall 3 sold on 2025-2026 does not work. 
You can leave it there for a powerwall 2 but that’s it.
Rename the integration at best.
For now I’ve signed up for the Tesla fleet API. I’ll see how it works I just feel bad I can’t poll as much as I want. Stupid Elon Musk ruining everything great to make $10/month from me.
I’m really happy it works for you. Do you have a powerwall3 or 2?
It may not work for you, that doesn’t mean it’s not working for others. If you have issues with your device, provide logs and screenshots in an issue on GitHub.
I have two PW2
A quick search on GIT will reveal it’s common with PW3. No need to open a issue or provide logs for a known issue
