Zigbee POPP Z701721 thermostatic radiator valve (TRV) – exposing all available items

The POPP Z701721 is a Zigbee TRV, which is also sold as white label under the Danfoss brand.

According to the data sheet (PDF) and to the Zigbee2MQTT entry for this device, it supports more channels than are currently exposed by the OpenHAB 3 Zigbee binding, namely:

  • Battery level
  • Battery alarm
  • Local temperature
  • Battery voltage
  • Occupied heating setpoint
  • System mode

I find that a number of the non-exposed items would be of interest, such as:

This TRV currently appears as a “Generic ZigBee Device”.

If it matters, I am running a POPP ZB-stick coordinator (Ember NCP, firmware 6.10.0.0).

What would be required to expose those extra items in OpenHAB?

Not sure if this might help (I don’t know the first thing about Zigbee, I’m basically just copying and pasting from Add support for SONOFF SNZB-02ZigBee Temperature & Humidity Sensor · Issue #638 · openhab/org.openhab.binding.zigbee · GitHub):

Any idea how I can add some of those missing items (clusters? Is that the right term?) to OpenHAB?

PS: If your browser truncates the dump horizontally, here’s the raw listing (expires on 2022-05-23): https://pastebin.com/raw/62y5QUBR

Also the Zigbee cluster specifications from the white-label Danfoss Ally version. As far as I can tell so far this is exactly the same product:

Sadly, I seem to be hitting a snag if I try to read a manufacturer-specific attribute (in this case, 0x4031 – “Heat Supply Request”, ref. the PDF above):

openhab> zigbee read 9040/1 0x0201 0x4031
Reading endpoint 2350/1, cluster server cluster Thermostat (0201), attributes Attribute 16433
Response for cluster 0x0201
Attribute 16433  Error UNSUPPORTED_ATTRIBUTE

This post from @chris suggests that there is a way to add those manufacturer-specific attributes to the Zigbee binding, though I’m still trying to figure out how.

This error comes from the device, so it means that the device doesn’t support this attribute. It may be that the request needs another flag which isn’t set here - I need to check this.

Thank you @chris. Is there anything I can do from my side to help out?
