How does the Smart Room Sensor work?
FAQ , Thermostats , Troubleshooting Modified: March 19, 2026
The Lennox Smart Room Sensor helps you dial in a more perfect environment by providing accurate temperature and humidity readings to the S40 Smart Thermostat and telling it how to balance temperatures across the rooms where the sensor is placed.
The Lennox Smart Room Sensor isn't just about perfectly balanced comfort; it can also help you save energy. When a room is in use, occupancy sensors keep your set temperature. When it's not, the sensors revert to a more energy efficient temperature.
