Radio Thermostat (3M Filtrete) Thermostat


The radiotherm climate platform let you control a thermostat from Radio Thermostat or 3M Filtrete. Your thermostat must have the Wi-Fi module installed and connected to your network.

The underlying library supports:

  • CT30 v1.75
  • CT30 v1.92
  • CT30 v1.94
  • CT30 v1.99
  • CT50 V1.09
  • CT50 V1.88
  • CT50 V1.92
  • CT50 V1.94 (also known as Filtrete 3M50)
  • CT80 Rev B1 V1.00
  • CT80 Rev B2 V1.00
  • CT80 Rev B2 V1.03
  • CT80 Rev B2 V1.09

New models that are derivatives of the CT30 or CT80 should be detected automatically and basic functionality should work.

To set it up, add the following information to your configuration.yaml file:

# Example configuration.yaml entry
climate:
  - platform: radiotherm

Configuration Variables

host

(list)(Optional)

List of your Radiotherm thermostats. If not provided the thermostats will be auto-detected.

hold_temp

(boolean)(Optional)

Boolean to control if Home Assistant temperature adjustments hold (true) or are temporary (false).

Default value:

false

Set hold_temp: true if you want temperature settings from Home Assistant to override a thermostat schedule on the thermostat itself. Otherwise Home Assistant will perform temporary temperature changes.

Multiple thermostats can be assigned by using host: if auto-detection is not used.

climate:
  platform: radiotherm
  host:
    - 192.168.99.137
    - 192.168.99.202

Humidity is now available as the current_humidity attribute for each climate.$HOST entity. This only works for RadioThermostat devices that have a built in humidity sensor.
