device_temperature_calibration offset is ignored

[Suchtaaa]

What happened?

Yesterday I completed my setup with an sonoff ZigBee dongle version p, zigbee2mqtt on a raspberry pi 4.

Everything works like it should. My three thermostats (Aqara SRTS-A01) are connected an can be controlled. The only thing which didn't work is the temperature offset (device_temperature_calibration).

I've tried to set it with the "ui" and also direct in the configuration.yaml. I read that it can take some time to take action on the device, but 12 hours should be enough.
The last thing I've tried was to restart the z2mqtt service.

But nothing changed.

Here is my configuration.yaml:
permit_join: true mqtt: base_topic: zigbee2mqtt server: mqtt://192.168.178.24:41883 user: Admin password: ********** keepalive: 60 reject_unauthorized: true version: 4 serial: port: /dev/ttyUSB0 advanced: network_key: - *** - *** - *** - 9 - 137 - 219 - 35 - 138 - 170 - 191 - ** - *** - *** - *** - ** - ** homeassistant_legacy_entity_attributes: false legacy_api: false legacy_availability_payload: false frontend: port: 8080 device_options: legacy: false devices: '0x54ef441000e15***': friendly_name: Thermostat_Livingroom thermostat_unit: celsius homeassistant: name: Wohnzimmerheizung optimistic: false device_temperature_calibration: -10 '0x54ef441000b83***': friendly_name: Thermostat_Kitchen device_temperature_calibration: -5 thermostat_unit: celsius '0x54ef441000b83***': friendly_name: Thermostat_Bathroom thermostat_unit: celsius homeassistant: discovery_topic: homeassistant legacy_entity_attributes: true status_topic: hass/status legacy_triggers: true

The Aqara SRTS-A01 does not have such a parameter as temperature offset.
For what purposes do you want to use it ?
p.s. Device temperature calibration appeared in the latest update, the purpose of the application is unknown.

Oh yes, youre right.. sorry my fault. I thought it was the offset for the measured temperature.
But curious that it doesnt work directly with the radiator.

I did some tests and saw, that the temperature sensor measures a bit (0,7°C) to high.. but next week I get some external sensors, so the problem should be "solved" :)
