Smart Climate Control Automations
Running a ceiling fan in an empty room is a waste of energy. To maximize comfort and efficiency, you should automate your fans to turn on only when the room is occupied and the temperature reaches a specific threshold. Here is how to build this smart automation.
Required Hardware
- A smart ceiling fan (or a standard fan connected to a smart switch).
- A smart motion sensor.
- A smart temperature sensor (like the Aqara Temp Sensor).
- A smart home hub (Alexa, Google Home, SmartThings, or Home Assistant).
The Automation Rule
Configure this rule in your smart hub app:
- Trigger: Motion detected in the room.
- Condition: Room temperature is above 74°F (23.5°C).
- Action: Turn on the ceiling fan to Medium speed.
- Safety Rule: Turn the fan off if no motion is detected for 15 minutes.
