Virtual Thermostat

Create a Thermostat in Home Assistant from one or more radiators and one or more temperature sensors

Perfect in order to create automations to control the temperature during day/night/away/weather based etc.

This AppDaemon app for Home Assistant require at least one sensor to get the current temperature from and at least one switch to turn on and off the actual radiator. Currently only Heating is supported.

MQTT

NOTE: You will need to have AppDaemon configured with MQTT support in order for this app to work.

This is an example appdaemon.yaml configuration file with the MQTT plugin enabled:

appdaemon:
  latitude:  57.0
  longitude: 12.0
  elevation: 12
  time_zone: Europe/Stockholm
  plugins:
    HASS:
      type: hass
    MQTT:
      type: mqtt
      namespace: mqtt
      client_host: 192.168.1.10
      client_id: AppDaemon
      client_user: appdaemon
      client_password: !secret appdaemon_mqtt_password

Quick Examples

Here are some example configurations for the appdaemon configuration file apps.yaml. If more than one sensor has been defines, then the average temperature between the sensors will be used.

Please Note: You need to change the entities to match your setup.
