Is this a problem in my setup, or is this a HA bug?
Everything done with a freshly paired Danfoss Ally TRV. The Z2M log at the end of the question.
I have paired my TRV with Z2M and named it trv.uf_office. In the Z2M map it shows properly connected with a high LQI:
In the developer tools it represents like this:
In the dashboard I have got a Entities Card with the climate.trv_uf_office (values here allready after update, details below):
Assume the TRV was set to 18 degrees. When I change the occupied_heating_setpoint of the TRV in the Lovelace dashboard to e.g. 23 now, then shows 23 for some seconds and then the occupied_heating_setpoint in the dashboard jumps back to 18.
But the TRV is set to 23 degrees and starts to heat after some seconds. When I check the Z2M logs, I clearly see the correct MQTT messages sent.
When I go to the Z2M Devices page, open up the view of the TRV → Exposes it shows all the values N/A or Null.
When I press the load value buttons (circulating arrows) for occupied_heating_setpoint and local_temperature then it sends the get MQTT messages and updates the vallues in the Z2M expose page and also the Lovelace dashboard.
But I would expect this to happen automatically when I change the temperature in the dashboard, and also when an autmation changes them.
To me it sounds like HA should send out the Received MQTT message on 'zigbee2mqtt/trv.uf_office/get' with data '{"occupied_heating_setpoint":""}' message whenever a change in the dashboard entitiy happens. This shouldn’t have to be done manually.
Is this a bug? Or just a PITA?
