[FR] Update MQTT reporting on change of state, mode, beerSet or fridgeSet

[denisfrench]

I have successfully setup capture of BrewPiLess data within Home Assistant via MQTT.

Control via MQTT is also working, but I have found the lack of immediate feedback makes programmatic MQTT control problematic.

Please consider updating MQTT reporting on change of mode, beerSet or fridgeSet, to complement the MQTT remote control functionality. Update of state upon change would also be useful for monitoring purposes, as it often changes within the Publish Period timeframe.

Likely this is relevant to MQTT control through other approaches, such as NodeRed, Python etc.

Thanks for your work on this 🙂

I have used your example from #432 and got brewpiless via MQTT into Home Assistant. The only control I can make work is to set the brew mode but I cannot set the temperature for fridge or beer constant.

EDIT - Actually I can only change mode to any setting except Beer Constant.

Got any tips?

Second edit - worked it out.

Are you certain it is not working? The key issue is that feedback via MQTT is delayed, therefore you will not see it update in HA until the next Publish Period. Check the BrewPiLess webif directly for real-time updates.

For this reason I have given up on control from HA, hence raising this FR.

The YAML from #432 (comment) was otherwise working fine for me. Probalby also check you have the full topic (ie it does not automatically include Base Path) in your "MQTT Remote Control" settings (#432 (comment)), which had me stumped for a while.

Concievably we could reduce Publish Period to 5 or 15 seconds and it would probalby work, but I would rather not spam my MQTT server, and wonder about the load on my BrewPiLess which already spontaniously resets occaisionally.
