Sonoff Smart Radiator Valve Review. Install on Danfoss TRV

Published at : 23 Dec 2025

In this video I review the Sonoff Thermostatic Radiator Valve Smart TRV. I unbox it, install it on a Danfoss radiator. I remove the Danfoss TRV and install the Sonoff TRV. Then get it working in the ewelink app via a Sonoff Zigbee Bridge. I also show it working with Home Assistant using Zigbee2MQTT via a Sonoff USB Dongle and in the Alexa App.
