Stop Cooling the Neighborhood: HVAC Window Automations
There is nothing more wasteful than running your central air conditioning while a window or back door is wide open. By connecting smart window contact sensors to your smart thermostat, you can automatically pause your HVAC system whenever a window is opened, and resume it once the window is closed.
How to Set Up the Routine in Alexa
- Open the Alexa App and create a new **Routine**.
- Set the Trigger: “When [Window Sensor] is Open for 2 minutes.”
- Set the Action: “Thermostat > Set Mode to OFF.”
Create a second routine to turn the Thermostat back to “Auto” or “Cool” when the sensor status returns to “Closed.” This simple automation can save you hundreds of dollars on heating and cooling bills.
