SONOFF Zigbee TRV

Hello,

Anyone using sonoff zigbee trv (TRVZB) ? I would need to buy about 10 pcs for my radiators and any feedback regarding integration in HA and operation would be very appreciate it !

Thank you !

Hi, no one is using this TRV ? Thank you !

I have had six of them running for about five months. I use Z2M and the integration seems solid enough with all options passed through to HA. I also run the Better Thermostat HACs which seems to work reasonably well too now but earlier versions were buggy. 1.5.0 beta 7 works for me, yet to try the full 1.5.0 release.

I also had an problem when updating the TRV firmware over Z2M. See post here: Sonoff TRVZB, zigbee2MQTT and BetterThermostat - #3 by danieljclark

Otherwise, they look nice, are cost effective and do the job. Battery life has been good, haven’t replaced any yet. Only major negative to me is the noise. I had seen a youtube review saying they were almost silent and mine certainly aren’t. About the same as an Aqara unit I have. Therefore I have to set a schedule to avoid adjustments in bedrooms at night to avoid waking people.

Sorry for very late reply, only just saw your question.

Features

This integration brings some smartness to your connected radiator thermostats setup:

  • Uses a temperature sensor far away from the radiators to measure the real room temperature
  • Makes your TRVs fully compatible with Google Home
  • Let your windows disable your heating (avoid programming this via an automation)
  • Your weather forecast provider will turn your heat on/off
  • Or an outside air temperature sensor can do this as well
  • Does some valve maintenance automatically, to avoid them getting stuck closed over the summer
  • Group multiple TRVs to one (e.g. for a room with multiple radiators)
  • Enhance the default TRV Algorithm with some smartness to reduce energy consumption.

TLDR, adds some extra features. In my view being able to use a climate entity that is situated closer to where you sit in the room and more accurate is the most impactful.

Hi Daniel, i intalled many of them and configured via better thermostat. Is all good !
Indeed, i think the main advantage is using the external sensor for a more accurate temperature
