Howdy.
A common query on here is "How can I determine if I switched a light on manually rather than by Indigo (say by motion detector)?
I've just pushed beta 1.0.34 of my Scene Controller plugin to Github
This adds support for On/Off devices (specifically Basic Set and Binary Switch classes) to the ZWave Scene Controller ecosystem, and thus allows you to trigger on an incoming ZWave On/Off command rather than on the traditional "Device State Change : On/Off" route. If you receive an incoming ZWave command, you know it's from a manual switch activation as Indigo sending a command wouldn't (normally) trigger an Incoming command back to Indigo.
If anyone is able to test it and report back findings or suggestions on usage, it would be appreciated.
