I just flashed an ESP32 relay board with ESPHome and it all works fine - I can see the entities on the dashboard and interact with the device; I can update the firmware wirelessly from ESPHome – yet the ESPHome home page in HA insists that it is “offline”.
I have a straightforward WiFi setup. It makes no difference whether I log on over the local WiFi or over Nabu Casa.
Software is all latest versions as of today…
Home Assistant 2022.12.6
Supervisor 2022.11.2
Operating System 9.4
Frontend 20221213.0 - latest
ESPHome 2022.12.1
Thanks for the reply. I will try the solution you suggest when I return home in January.
‘BTW’ I did search but did not find this solution. I only go to the trouble of posting after I have searched the internet and tried all the solutions I could find as well as any possibilities I can think of. Perhaps there should be a way of adding searchable keywords to solved issues? The problem with searches now is that you have to wade through a lot of irrelevant issues and those that have no solution’ so I guess it is easy to miss one.
