This blueprint uses an external temperature sensor to calibrate a Zigbee TS0601 which is connected to Zigbee2MQTT. It is slightly different from the ones previous found in the Blueprint section of the Home Assistant forum, since those expect the "local_temperature_calibration" attribute to be part of the TS0601 entity itself.
When in Zigbee2MQTT the "Home Assistant legacy entity attributes" is disabled, when disabled Zigbee2MQTT will NOT add state attributes to each entity, therefore there is no 'local_temperature_calibration' attribute in the TS0601 entity.
Using this Blueprint the following entities have to be provided;
- TS0601 radiator valve with thermostat
- External temperature sensor
- local_temperature_calibration entity (of the TS0601 element)
