Scenes, Robots, and Thermostats are incompatible with "device" interface #74
Description
The "Device" interface implies that an API entity will have the following units which thermostats, robots, and scenes do not reliably have:
- unit (for sensor reading)
- state (particularly for Scenes)
- device manufacturer (We may be able to fall back to "Wink". for this)
- device model name
It may be possible to extract a more simplified interface for these objects.
