Hi folks,

Unfortunately, I have once again purchased a device that is probably not supported. :-(

It is listed at Zigbee2MQTT so I thougt, that it's also already supported in this adapter.

Here a Screenshot of my ioBroker:

Give it time. We are battling a number of critical errors. Once those are gone we can up the zigbee-herdsman-converters used to include the support for this device.

I'll give it the time you need. I only wanted to know if I have to buy any other thermostats ...
If I can help you with any data let me know. :)

I have hope to be able to give you at least a temporary version by 1.11. If the device is properly integrated into zigbee2mqtt.io, chances are good that it will just work once we use the same library version

Today i updated to 1.13 and the TRV is now supported.
But I still have problems with the settings.

The TRV doesn't take the temperatures I set in the scheudule. No matter what I put as temperature it sets the antifreeze temperature:

Also the chance of the min_temperature doesn't update every time I change it. At the moment I don't know when it reads the new values.

Just a little contribution on the identification of the Tuya TRV602Z device.
Mine is reporting Zigbee Manufacturer "_TZE204_ltwbm23f" in Z2M, and this is visually the same model as the picture in the first message of this issue.
Moreover, it's written "Model: TRV602Z" on the device itself.
I bought it here https://fr.aliexpress.com/item/1005004733341777.html?
And it's advertised as a "TRV602Z" from the vendor.

The schedule is not working also for me.

I did a simple test. Factory default schedule is "06:00/20.0 08:00/15.0 12:00/20.0 14:00/15.0 18:00/20.0 22:00/15.0" for all days. I just changed the schedule for one day to "06:00/19.0 08:00/17.0 12:00/19.0 14:00/17.0 18:00/19.0 22:00/17.0" (without touching hours, just the target temperatures to be sure that I was not wrong on the time periods syntax).

For the day where I changed the schedule, the TRV displays the antifreeze icon and target temperature is 5°C. For other untouched days, it's OK, it works according to schedules.

Also, the motor thrust setting is not working.

Here is an update. After migration to v2 where an improvement on this TRV is mentioned, I still have the same problems:
When I change the schedule, the TRV displays the antifreeze icon and target temperature is 5°C.
Motor thrust setting is not working (no effect if I change it).
