### Zigbee2MQTT version
1.41.0
### Comments
I bought one TRV from the page, and it was _TZE204_rtrmfadk - working great. So I bought some more from the same seller, and all are _TZE204_qyr2m29i. They look absolutely same, but does NOT work with the same converter. The best I could find is this.

### What does/doesn't work with the external definition?
**Works**:
Child lock state
Current heating setpoint (but only in 1C step, not 0.5C)
Local temperature
**NOT WORK**
System mode (does something, but completely wrong)
Running state (empty)
Local temperature calibration (works, but indicates step 1C, actually changes in step of 0.1C, and is limited to -0.9..0.9
Missing:
manual mode
Position
battery %
MAX/MIN temperature
Window detection
Preset
System mode
Mode (comfort/eco)
