Tuya TRV , Domoticz

Good afternoon complete newbie so please bear with me

I have the attached TRV connect to my Conbee2 stick

Couple of queries

  1. the Temperature on my vale reports about 2 Degrees more than the temp sensor in the room

  2. I Cannot see the valve in my phonscon app but I get the below in Domoticz Devices

  • Temperature
  • off/Boost/Auto select switch
  • valve set point

I cannot see see window open switch or valve % position

Any ideas how I can get the trv to report the correct temp and obtain valve position

Thanks in advance


Hello, for the 2°C issue, I think it’s the same problem than here https://github.com/dresden-elektronik/deconz-rest-plugin/issues/5394

The correctif is already done and in waiting list. You can compile it if you want to try it ? https://github.com/dresden-elektronik/deconz-rest-plugin/issues/5394#issuecomment-947827955

For the % valve, not all device have it, so I m not using it in domoticz (but can add it if needed). Can you give me the manufacture name of the device ? Something like _TZE200_XXXXX to check if it s a deconz/tuya/domoticz issue.


Thank you for quick response and help much appreciated my

My TRVs is as follows


Would you also be able to send me a link guide to upload the fix imegion I have to move to beta version ?

Attached is my current version

Thanks in advance

I can be wrong (There is a new tuya trv every week) but if I m right it’s this one ? TuYa TS0601_thermostat control via MQTT | Zigbee2MQTT

And on Z2m description I don’t see the valve state return, there is a setting “valve_detection” but I don’t see what is it for …
Haven’t found a json sample on deconz for this device.

On domoticz / custom / deconz / sensor you will have all setting, you can just take a look if you have “null” or if the value is moving for the valve state to be sure if the code support it.

Would you also be able to send me a link guide to upload the fix imegion I have to move to beta version ?

I think yes, you can compile the code on stable branch, but unfortunately I think the deconz-dev package is too old on this branch. The PR is still in waiting list, so not available in beta yet, so need to compile the lib.

If you are on standard OS (no docker)
Here you have the way to switch beta <> stable ConBee II Installation
And here the command to use to compile the PR https://github.com/dresden-elektronik/deconz-rest-plugin/issues/5394#issuecomment-947827955

You don’t need to re-include the device or update the firwmare.
