Description

I currently have 6 BT-instances with single TRVs installed. All with the same devices:

  • Bosch Thermostat II as TRV
  • Sonoff SNZB-02D as external Temp.-Sensors
  • [SNZB-04] as Window Detection Sensor

4 of 6 BT-Instances work perfect but two of them get the target temperature set to another value (always the same values for each entity). The strange set to another target temperature value only takes place if the target room temperature has been reached and the heating is stopped by BT. So without correcting the target values in the UI, the origin target temperature will not be reached / heated to again.

Playing with child look, removing external outdoor temp sensor, removing and reinstalling entitiy and devices, playing with any settings didn't fix anything.

One entitiy is setting always back to 15,5°C, the other one to 5°C.

Steps to Reproduce

  1. Set desired target temperature (e.g. 20°C) and activate heating
  2. Wait until room temperature has reached 20°C -> Heat off / heating PI demand 0%
  3. Target temperature changes itself to static (always the same) value (e.g. 5°C)

Expected behavior:

Turn heat off and maintain target temperature for each entitiy.

Actual behavior:

Target temperature is set to some static value after reaching setpoint (-> heat turning off).

Versions

HA 2024.9.2 BT 1.6.0 Zigbee2Mqtt 1.40.2

Additional Information

Debuggin the BT Integration shows some strange function called "trigger_trv_change test" which seems to be responsible for the change of target temperature.

Im not really into the code of BT, but a function called "test" at the end doesnt seem promising. What does this function do in detail? Have look at the line
