The MRCOOL® Remote Room Sensor is the key to achieving true, balanced comfort throughout your entire home. Designed to work seamlessly as an optional add-on to the MRCOOL® MST07 Smart WiFi Thermostat, this sensor allows you to move beyond basic hallway temperature readings to monitor specific areas where you spend the most time. Whether you’re dealing with a drafty bedroom or a sun-drenched living room, these sensors provide the precise, real-time data needed to eliminate hot and cold spots for a more consistent indoor environment. Integration is effortless and entirely DIY-friendly, mirroring the intuitive setup of the MRCOOL® Connect app. You can expand your system’s intelligence by connecting up to 10 sensors to a single thermostat, creating a comprehensive multi-room monitoring network. By providing your HVAC system with a clearer picture of your home’s climate, these sensors help drive smart automation that reduces unnecessary runtime. The result is a more responsive, energy-efficient home that prioritizes your comfort while actively helping to lower your monthly utility costs.
