ESP2866 sometimes disconnects from API after toggling

[RonnieLast (Last of the Ronnies)]

On the basis of “[api.connection:159]: Home Assistant 2022.3.5 (192.168.0.63) requested disconnected”, that means it’s HA doing the disconnecting. Are there any logs from HA in relation to this?

Device keeps disconnecting from Home Assistant if too many entities

You might want add a WiFi signal sensor A weak WiFi connection is often breaking ota capabilities.

I’d suggest that you test this with the coffee machine very close to the WiFi and see if you still have issues, or try pinging the ESP for a period while the issue happens and see if you get latency jumps which might indicate WiFi issues.
