Unfortunately I don't have an answer to this. The specs can vary from device to device, and when SEQUEmatic retrieves the list of devices it also gets the specifications for the different properties. This is normally displayed under the value field when you're creating the step.
I noticed for scene_data_v2 this wasn't displaying so I've checked the logs and confirmed that the Tuya API isn't returning anything for this either. I'll have a look online for some more documentation, but the best I can suggest right now is to Google further (unless someone else can share some insights here).
