The climate platform integrates Honeywell US-based thermostats into Home Assistant, allowing control of the thermostat through the user interface. The current inside temperature, operating mode, and fan state are also displayed on the thermostat card.

All climate services are supported except set_swing_mode.

There is a “known” issue related to setting the temperature from Home Assistant with some thermostats. If your instance receives errors when setting the temperature above or below some value, go to the Honeywell web page and set the temperature to the max or min for the mode you are using, then adjust from Home Assistant.


The sensor platform integrates inside and outside temperature and humidity into Home Assistant as sensors for each device. Not every supported thermostat will support all sensors.

This integration will add Home Assistant sensors for the following:

Sensor Value
Outdoor temperature Average temperature of all Honeywell Wireless Outdoor Sensors
Outdoor humidity Average humidity of all Honeywell Wireless Outdoor Sensors
Indoor temperature Current temperature as measured at the specific thermostat
Indoor humidity Current humidity as measured at the specific thermostat
