I bought a Zipato Bulb 2. The datasheet and user's manual are very minimalist with no comprehensive description of the available commands. I looked into the XML description of OpenZWave but it is also incomplete.
So I asked Zipato directly, but the contact I made is not on the technical side and he doesn't know what I am talking about.
How am I supposed to interact with Z-Wave products if I don't know the command they provide?
I'm not sure if you've seen this information, but here's a link to the user manual for the Zipato Bulb 2. It covers the command classes that the bulb uses. It should be the same as the OpenZWave XML file.
The devices don't usually come with much more documentation than that. Is there something you still don't understand after having read it?
