I got some devices (8286…) that work perfectly well, even the addon refuses to start. I got a popup saying “Unknown error, see supervisor”. Love it, almost Windows blue screen silly message haha.
Sorry just joking.
I’m on HA Supervised on Debian 11, virtualized on HyperV, Windows Server 2019. Yeah, quite not the simplest install, but everything works seemlessly but that strange issue.
Python is 3.9 (I’ve read some issues about that), and ESPH is 2021.9.3.
Core and Supervisor run latest releases, Docker is 2.10.8.
I have had the same issue but only after downgrading to core-2021.9.7
I found a older post where they just reinstalled esphome remove it and install again it worked for me also
Was bit scared cause i dint whant to loose my devices but my trough i can always do another full restore
Just google that error or on the forum i had the exact same issue
I have resolved it by reinstalled i am not sure about the risk but my trough was i can always do a full restore
Thank you a hundred times. I’ll first make a backup through Samba/Windows, because it appears, as in the tread you mention, that ESPHOME can’t backup. But it shoul be no risk as a lot of people seem to have solve this like you with no damage.
