# SONOFF thermostats and radiator valves

*SONOFF / 3 models*

> SONOFF's heating range is two Zigbee radiator valves and one Zigbee wall thermostat. All three need a Zigbee hub or gateway and are listed for Zigbee 3.0. The TRVZB and the TRV Gen2 (TRV-ZBT) both fit M30 x 1.5 mm valves, and the TRV Gen2 adds a rotating colour display. The Thermostat Core (TP-WGZBA) switches a hydronic actuator or signals a boiler through a dry contact, and it is not rated for direct electric underfloor heating.
