Hello everybody!
I managed to set up home assistant and zigbee2mqtt on a raspberry pi. I bought some Zigbee capable TRVs (Thermostatic radiator valves) and managed to make them work with home assistant.
I found out how to set up weekly schedules for different temperatures etc. Now everything works.
But sometimes, some TRVs don’t get new temperature values. When I force a retransmit, it works.
Now I have some questions:
- is it guaranteed that HA always triggers a set temperature when it is performed as an ‘action’? Or is it known that sometimes actions are lost?
- is it a zigbee transmission issue? If I trigger a set temperature once, is there a kind of handshake? E. g. does HA read back the value to ensure that it is properly set?
- I solved the issue somehow by setting the temperature not directly but store it in a ‘input_number’ and use an automation which triggers once every five minutes and compares the input_numbers value to the TRVs value. If they deviate, a set temperature at the TRV is triggered.
Thank you for reading this…
