If I use indigo.devices.subscribeToChanges(), in the callback deviceUpdated() a plugin receives two objects, the original (pre-change) Device and the new (post-change) Device. This is fine. However, the objects do not indicate whether Indigo originated (sent) or received the triggering event. I assume that this is because indigo.devices.subscribeToChanges() is triggered by an update to Indigo's database.

Would it be possible to include information in the objects sent to deviceUpdated to indicate whether Indigo had originated or received the change?

I realize this could be a giant can of worms since one INSTEON command sent could result in several received (links, etc.) and of course, now that we have plugin devices it is even more complex. But, I thought I'd ask anyway.

BTW, the reason for wanting to know this information is to allow a plugin the option of only triggering on received events (I.e. I might want to know when the actual switch was operated, not just when the light was turned on). I realize I can subscribe to incoming events (indigo.insteon.subscribeToIncoming()) as well. But, if it is necessary to also track sent changes, then subscribing to and managing both streams could be a real pain.

Having a changeOriginator type of argument is a good idea. However, the changes required to implement it are pretty significant given how many places states can change. But we'll keep it in mind the next time we are working in those areas.
