Overview Shelly TRV WIFI thermostat

The Shelly TRV is a radiator thermostat with WLAN. The function block can either set the valve position directly or hand a temperature setpoint to the thermostat and let it control on its own. Which of the two modes applies is set with the type parameter.

Inputs

ST Temperature setpoint Setpoint for the room temperature in °C. Only effective with the setting temperature control.

Outputs
SV Valve setpoint % status Feedback of the present valve position in percent.
ST Temperature setpoint status Feedback of the setpoint set in the thermostat.

BA Battery State of charge of the battery in percent.

Parameters

MQTT topic Topic of the device. Devices of the first generation automatically prepend shellies/, this part has to be entered here as well. Example: shellies/shellytrv-AABBCCDDEEFF

Type
  • Valve control: The setpoint for the valve is set. For this option the automatic control has to be disabled at the thermostat.
  • Temperature control: The temperature setpoint is set and the thermostat controls the valve itself. For this option the automatic control has to be enabled at the thermostat.
  • Display only: Neither valve nor setpoint are controlled, the values are only read.
In addition to the outputs listed, the command generate addresses creates an address named timeout. It is set to 1 when the device has not sent a message for a longer period of time.
