Thermostat recognized as a light

Configuration Z-Wave
1

Hi folks

I’m in the process of switching from my dying 14 year old Vera 1 to some other Zwave controller. Tried Hubitat, but it’s unstable (hangs every few days).

So now trying Home Assistant with ZST39 and Zwave JS UI.

Tried adding my dinosaur Wayne Dalton thermostat:

It was recognized as a light switch :frowning:
Perhaps not surprisingly, since it’s quite an old device.

Now, Hubitat had the same problem, but gave me an option of treating it as a “generic thermostat” and that worked. Most of the commands I needed to control it (switch cool/heat mode, set cool/heat point, etc) worked.

I was wondering if there is a similar “override” mechanism in HA?

Thank you in advance

It should appear as a climate entity. Post the device diagnostic file, available from the Device page → … menu.

In this current state the device cannot be used in HA. Z-Wave JS is not providing the information necessary to use it. I would do the following:

  1. Turn on driver debug logging (debug level and driver, not application). See https://zwave-js.github.io/zwave-js-ui/#/troubleshooting/generating-logs?id=driver-logs
  2. Re-interview the device. Either this will fix the problem, or you’ll generate logs that can help to fix it.
  3. If after the re-interview see if you now have a climate entity. If you don’t, report a new issue at node-zwave-js.

If you have to submit an issue, you should include the driver log with the re-interview. You could also include the device diagnostic.

The problem is either a failed interview, or the device is old or buggy and doesn’t report it’s capabilities correctly. For the latter case that needs to be fixed by Z-Wave JS in order to be usable in HA. You can see in the OpenHAB database that it supposedly supports the necessary command classes (COMMAND_CLASS_THERMOSTAT_MODE_V3, etc), which are missing from your diagnostic.

Thank you. Created

Looking at the logs, the node reports supporting all these commands:

But reports version 0 for each command and driver interprets it as unsupported?
