    # Automation especially for the Bosch Thermostat II ([BTH-RA](https://www.zigbee2mqtt.io/devices/BTH-RA.html#bosch-bth-ra))

    ## Core Features

    - Switch the TRV on/off depending on a window sensor

    - Sync the value of the temperature sensor to the TRV's internal `remote_temperature` entity (there's no need to calibrate it manually via `local_temperature_calibration`)

    - Based on a weather entity and a winter temperature the TRV will be switched off to avoid heating in the summer

    ## Notes

    - Maybe this blueprint works also for other TRVs. The required entity of the TRV: `remote_temperature`
