Hi, I have a Zen Thermostat that I'd like to have supported by DeConz.
Here are the node and cluster info screenshots.

Hi, I was just looking for a thermostat to use in HomeAssistant. Either through Wifi or ZigBee. This Zen one has a really nice design. Are you planning on adding this to REST API?

Have a nice day :)

Hi, I wonder if the Zen thermostat is fully supported. Google searches suggest that is not the case since I haven't seen anybody posting a successful implementation.
While I am able to join the network with the Zen thermostat, the device is not visible in the Phoscon app. From there I plan to use it in Homeseer but at the moment this is not possible.
Can anybody comment, please?

For anyone who is reviewing this ticket to confirm support, I can confirm full ZEN thermostat compatibility for temperature reporting and control & mode reporting and control. It's rock solid, and vastly superior to the MQTT implementation 👍

Reviewing your previous comment @ggg22 , the ZEN doesn't appear in Phoscon UI for me either, however I think that's unnecessary as it is fully supported by the Deconz REST API so should work just fine with downstream integrations. For example I'm using Home assistant and the device is exposed with full compatibility out of the box now.

Two FYIs

  • Full device support was implemented in the most recent Deconz beta version 2.05.79
  • There is a configuration issue in 2.05.79 beta (which I suspect will be fixed in stable) whereby temperature isn't reported from device to HA by default, however it's simply resolved by updating Thermostat Cluster attribute 0x001C 'System Mode' as follows (via VNC interface)
    -- Min Report Interval = 1
    -- Max Report Interval = 600
