Product Identity

The Meross MTS215 is a Matter smart thermostat built for 120 to 240 VAC electric baseboard, convector and fan-forced heaters. It targets homeowners who want voice and app control of high-voltage heating without ecosystem lock-in.

Voltage Compatibility

This unit only works with 100 to 240 V line-voltage systems and is not compatible with 24 V HVAC, heat pump, air-conditioning or electric underfloor heating. The casing dimensions of 118 x 75 x 43 mm suit North American junction boxes.

Sustained Operation

Energy monitoring reports real-time electricity use and historical trends in the Meross app. Open-window detection pauses heating automatically when a draft is sensed, preventing waste during long periods of ventilation.

Questions about this item

What does the 120-240 VAC rating mean for my electric baseboard heater?

The thermostat connects directly to high-line voltage wiring used by baseboard, convector, and fan-forced heaters, so no separate low-voltage transformer is required.

How does Matter support work across Alexa, Apple Home and Google Home at the same time?

The device joins your Wi-Fi network and exposes a single Matter accessory that each platform can control simultaneously without extra bridges.

Will the 1.7 in x 2.9 in x 4.6 in casing fit a standard North American junction box?

The dimensions correspond to 118 x 75 x 43 mm and are designed for North American wall boxes used with 100-240 V electric heating systems.
