[Device Support Request] TS0601 _TZE200_hue3yfsn / TV02 Zigbee TRV

Is your feature request related to a problem? Please describe. I bought this thermostat from AliExpress. It’s possible to pair with ZHA, but no entities are exposed.

Describe the solution you’d like Ideally, I’d like to control all settings these Tuya based thermostats have. I know that Zigbee2MQTT seems to be able to do that (Source)

Additional context The thermostat has no branding whatsoever (neither the device itself, nor the packaging material), I can’t tell who is the actual manufacturer. In the included manual it’s refered to as TV02 Zigbee Thermostat Radiator Valve I bought it from this link: AliExpress

Great new guys I’ve finally cracked the online mode! Now I’m are able to set the device into online mode, where it for ca. 1 minute constantly publishes all values including current temperature.

The code will follow in short.

EDIT code is here you can test it. I’ve created a third on/off switch, because we cannot use HA button entity, which is shame. To better distinguish this on from the others, it has reverse polarity. It’s constantly in ON-State and by switching it to OFF-State you’ll actually activate the online mode. Then, after few seconds, the switch goes back to ON-State, so you can active the online mode again. You can also keep the device in online mode, just keep turning the switch to OFF-State, you cannot deactivate the online mode in TRV. It will expire automatically 1 minute after last online command was sent.

NOTE this will consume your battery, so use it only from time to time.

I was able to implement: - heating operation off/heat - present manual/schedule/holiday - opened window detection - child lock - fault (not able to test) - temperature offset

Probably this TRV will be needing its own class because I can’t test it with original ZONNSMART. The behaviour like ability to turn it off is missing on most devices like SITERWELL or LIDL.

Unique behaviour of this TRV:

###Off You can turn this TRV off, by setting ZONNSMART_HEATING_STOPPING = 0x016B to 1. On the TRV will be show HS (heating stopped) and you can’t do anything till you deactivate it.

###Present Manual and Schedule works like expected but holiday mode cannot be started by selecting the mode. It only shows the holiday mode temperature and after 5sec it switches back to schedule mode. (FYI holiday mode is activated automatically by setting begin and end timestamp = not implemented)

###Frost Protection (not implemeted) I don’t know how to implement this one, because it’s like one of those Present Modes. After setting ZONNSMART_FROST_PROTECT_ATTR = 0x010a attribute, on TRV will be shown AF (antifreeze), it sets temperature to 8 degrees and you cannot do anything until you disable this.

###Don’t publishes room temperature This TRV never publishes room temperature, it has to be manually requested. Currently the only way is to set temperature offset (even with 0), after that the room temperature will be published.

If someone will test it, here is the quirk: valve.zip but for presets to work, you have to add to /components/zha/climate.py following lines:

    channel_names=CHANNEL_THERMOSTAT,
