It has 615 installs sharing analytics, works locally and was last updated October 23, 2026. Dual Smart Thermostat is a climate integration that switches a heater and an air conditioner from a temperature sensor. It extends the generic thermostat with heat only, cool only, heat and cool, heat pump and two stage heating setups. Settings cover tolerances, a minimum cycle duration, a keep alive interval and temperature limits. Optional features include a fan, humidity control with a dehumidifier, window and door sensors, floor temperature limits and presets such as Away, Eco and Sleep. It works locally and is set up in the UI. Automatic summary of the README and code of swingerman/ha-dual-smart-thermostat. Something wrong, or are you the maintainer and want your own text here?
