Appdaemon: how to observe a zwave config parameters?

I have some innovelli light switches that include zwave config parameters. I can see the config parameters in the zwave device page on Home Assistant, but there does not seem to be any associated states for them. I cannot seem to figure out how to read off the config parameters from appdaemeon.

As a partial help, supposedly a trigger can be set up on zwave_js.value_updated to at least see state changes as an event. Alas, I don’t see how to translate this into an appdaemon observable event either.
