Revert to local control, e.g. RC310, if connection to home automation fails

[airhead1234]

I use EMS-ESP32 to control some elements of my heating and hot water by Home Assistant and this works great.

Very rarely, Home Assistant crashes, Home Assistant loses network connection or EMS-ESP loses network connection. In these cases, heating and hot water may remain in settings that are not good because EMS-ESP32 cannot receive updates from Home Assistant anymore. As an example, Home Assistant provides the temperature of a virtual room sensor to EMS-ESP. If Home Assistant fails this temperature would not reflect the actual temperature any more and maybe heating would not be turned on even though it has gotten colder.

To mitigate this potential issue, I am wondering if EMS-ESP32 could regularily execute a healthcheck on Home Assistant and, if this healthcheck fails, set the values of several entities to predefined values. As an example for the situation described above, EMS-ESP32 could change the temperature monitoring from the virtual sensor to the local RC310 if Home Assistant is not available any more.

Do you think this feature could be of value to people other than me and that it could be implemented?

Thank you for your consideration.

I'm still thinking about how to do this!

Was this your intention?

No, this is a bug. Fixed now in my dev.

I have tested the new dev version and the bug is gone. Thank you!

[proddy]

thanks, which version did you check it on?

[airhead1234]

I used Michael's dev 10 from https://github.com/MichaelDvP/EMS-ESP32/releases/download/latest/EMS-ESP-3_7_0-dev_10-ESP32_S3.bin.

Happy to try another one if you want me to.

ah thanks. That's also in the official dev 10 and 11 now so we can close this
