I have multiple Sonoff TRVZB devices and most of them are working except one.
The device is connected to my network and I receive status updates e.g. if I set the temperature at the device directly by turning the wheel the target temperature is updated in HA. But when I set the temperature in HA I get an error, not only when setting the temperature, no matter what I try:
error 2025-02-09 15:41:34z2m: Publish 'set' 'local_temperature_calibration' to 'Thermo Bathroom' failed: 'Error: ZCL command 0x44e2f8fffe0c6d96/1 hvacThermostat.write({"localTemperatureCalibration":22}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":true,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (Delivery failed for '53362'.)'

All the other devices work great. I already removed it from the network and did the interview again, the firmware is up to date. It worked before, but no I can’t change the status and google search or in this forum didn’t help me either.
I’m on HA 2025.2.1 on a Raspberry 5 8GB with Home Assistant OS 14.2.
I use Zigbee2MQTT 2.1.1-1 and Mosquito Broker 6.5.0.
Finally my devices are connected with a Sonoff Zigbee USB 3.0 Dongle E Plus V2 with firmware EmberZNet 7.4.4.
I also tried different firmware versions but the behavior is the same among them all. The only difference is more stability general and OTA working well witht his version (except one other TRVZB that always makes the network crash when trying the OTA update).
Any hints and pointers are welcome, I’m fairly new to Home Assistant and Smart Homes in general.
If any additional logs and info are needed I’ll gladly provide them.
