I bought a Home Assistant Yellow from the Home Assistant people so it would just work. It came with an old software version and demanded an update. 9.x to 10.x went fine. It demanded another update. 10.x to 11.0 and it’s bricked. No HTTP. No SSH. No factory reset.
This is disappointing. At least I didn’t even have a chance to set anything up, so things work just as well with it dead.
I had previously run HA on a Raspberry Pi with Z-Wave, Sonoff, and some Hue, years and years ago. After searching for a Zigbee (since that seems to be the current standard and I’m starting over) adaptor that was HA compatible, I saw they offered their own hardware. After 18 months of waiting, I figured it would “just work.” Anyway, I reimaged over USB-C and it’s working. I’ll definitely do a backup before doing my first software update now that I have something to lose.
