The reflash with konnected firmware didn’t solve the instability issue so I’ll take it to konnected support.
fwiw I’m pretty sure the problem I had with updating from the ESPHome add-on in homeassistant was from the “pin reuse” thing described here. So my hunch is once you got around that you would be able to ecit ESPHome configs on the konnected board from the ESPHome add-on…
