SONOFF TRVZB 4-Pack - Thermostatic Radiator Valve

The SONOFF TRVZB Zigbee Smart Thermostatic Radiator Valve, 4-Pack is a set of four thermostatic radiator valves for controlling water-based radiators. Each valve uses Zigbee 3.0 and can be adjusted via a smartphone or tablet app, voice commands, or directly on the valve itself. Amazon Alexa and Google Assistant are supported, and Apple Home integration is available through a Matter Bridge. A PID control algorithm regulates each valve to maintain the selected room temperature. The valves can be managed independently for separate radiators, rather than treating the pack as a single heating control.

Each unit has a PC housing and attaches to the radiator with an M30 × 1.5 mm threaded connection. Because the installation uses the existing valve fitting, it is important to check the thread size for compatibility. The product is listed as compatible with standard M30 × 1.5 mm radiator valves. Its wireless connection is Zigbee, with no Wi-Fi or Bluetooth connectivity specified. The four-valve pack is intended for controlling multiple radiators in the same home or property.

Key Features:

• Three 1.5 V AA batteries per valve power the unit.
• Weekly schedules automate heating periods for different routines.
• Open-window detection, frost protection and a child lock are included.
• Home Assistant and ioBroker compatibility allows integration with those smart-home systems.
• Dimensions of 59.4 × 59.4 × 95 mm should be checked to ensure adequate clearance around the radiator valve.
