MST07-S Additional Room Sensor for MST07

The MRCOOL® Remote Room Sensor is designed to help deliver balanced comfort throughout your entire home. As an optional add-on for the MRCOOL® MST07 Smart Thermostat, this sensor allows you to monitor temperatures in the rooms that matter most instead of relying solely on hallway readings. Whether you’re managing a drafty bedroom or a sun-filled living room, the sensor provides precise, real-time data to help reduce hot and cold spots for a more consistent indoor environment.

Integration is simple and DIY-friendly through the MRCOOL® Connect app. Connect up to 10 sensors to a single thermostat to create a comprehensive multi-room monitoring network. By giving your HVAC system a clearer picture of your home’s climate, these sensors support smart automation that reduces unnecessary runtime. The result is a more responsive, energy-efficient home focused on comfort while helping lower monthly utility costs.
