Meross / 6 models
Last checked
Meross thermostats use Matter: the MTS300MA for heating and cooling systems with a C wire, the MTS215MA for electric heating and the MTS215BMA for boilers.
The MTS215MA is sold as a US model for line-voltage baseboard heaters and an EU model for electric underfloor heating. The MTS155 is a radiator valve that uses Matter over Thread. The MCA100 adds a C wire for thermostats that need one.
