  name: Aqara TRV E1 External Temperature Control
  description: >
    This automation allows the Aqara TRV E1 Smart Radiator Thermostat to use temperature readings from an external sensor rather than its internal sensor. Whenever the temperature sensor reports a new value, it is sent to the TRV for more accurate climate control.
