The toon integration platform can be used to control your Toon thermostat. This integration adds a climate device for your Toon thermostat, sensors for power and gas consumption, sensors for solar production and several binary sensors for things like boiler burner on/off, hot tap water and boiler health status.

For the toon integration to work, you’ll need an active Toon subscription with Eneco and a Toon API developer account.

There is currently support for the following device types within Home Assistant:
