Understanding RazBerry "Dimmer Endpoint" virtual devices

Post by willimur » 29 Oct 2018 22:00

In my z-wave network, my RaZberry seems to advertise that it has 16 "Dimmer Endpoint" instances. I can see it if I use my SmartThings controller UI...

...as well as if I look at the "Expert Commands" tab of the Z-way-server Expert UI configuration screen.

But if I try to access any of these instances, it appears they do not respond to any API calls. If I try to execute something apparently simple like calling SwitchBinary.Get() I get an error: "Error: Method not implemented devices[15].instances[0].commandClasses[37].Get()"

I'm just trying to understand what these 16 instances are, and how they are meant to enable a developer/experimenter to expand the RazBerry's functionality. Looking around, I have a feeling that these are defined in the z-way-server/config/Defaults.xml file under the <Channels> section.

A few questions:
  • Does anyone use this functionality? Is it commonly used in the downloadable/installable "Apps" as ways to expose their functionality to the rest of the z-wave network?
  • If I wanted to expose a sensor reading that my Raspberry Pi captured (e.g. via an attached sensor) would I create some custom user module in z-way-server/automation/userModules and somehow "bind" to the appropriate device[#].instance[#].commandClass[#].Get API endpoint? If so, are there any examples of how to do that?
Or am I just completely misinterpreting how this stuff works?

What device does your SmartThings hub discover your Raspberry Pi?

The quick answer to your question is "go look up multi-instance and multi-association". When I get a chance I will write up a longer reply.

RaZberry indeed to have multiple channels and SwitchMultilevel and SwitchBinary on them. This is for support if old devices.

But you can use this to export data to SmartThings: use
devices[15].instances[0].commandClasses[37].data.level=... to set it and SmartThings can request those values.

devices[15].instances[0].commandClasses[37].Get() is not working because it is strange for the controller to request itself ;)
