Room sensors are small wireless devices placed in different areas of your home. They measure temperature — and in some cases occupancy — and communicate with your thermostat.
How it works:
- Place sensors in key rooms
- Sensors detect temperature and motion
- Thermostat prioritizes occupied rooms
- HVAC adjusts to balance comfort
This is why the best smart thermostat with room sensors can dramatically improve comfort compared to a standard thermostat.
