I’ve been using HA for ~5 years and had Tesla Fleet API integration since November 2024 when I got solar panels installed. Starting about a month ago (mid-January) I noticed the data stops coming in and when I check HA I see “Authentication expired for ” for the Tesla API. I have to then re-auth with Tesla and it starts working again. Wondering if anyone else is experiencing this. It was working fine for over a year and then just started being very annoying.
HA version (docker):
- image: linuxserver/homeassistant:latest
- Core 2026.2.3
- Frontend 20260128.6

I have been noticing this too and think this has to do something with the Home Assistant Core package that was released in January.

Same here. Found that reloading the integration fixes it without going through the authentication on tesla dev site. I’ve not determined the frequency since i’ve been doing a lot of rebooting/reconfig on home assistant lately.

Just happened to me again today at ~17:30. Looking in the log:
2026-03-04 17:32:13.028 ERROR (MainThread) [homeassistant.components.tesla_fleet] Authentication failed while fetching Tesla Fleet Energy Site Live data: The OAuth token has expired.
I just tried bouncing HA container (without doing explicit tesla reauth) and it seems like that’s pulling data back in. Wonder if I can just load an older container tag without corrupting some database.
