Any way to know what triggered a state change?

There is already a feature request here:

Awesome Switch triggered_by Attribute For Happy Automations!

Removed your name from the quote. As a part of the trigger object would certainly work for me. I am not that familiar with the HA codebase, but adding a source to the trigger object doesn’t seem like a lot of work. Of course it wouldn’t prevent collisions between automations, but you’d be a step closer to detect those. Which other system are you using that supports this kind of stuff? Maybe we can learn something of that platform.

And someone in there mentioned that is already in the To-Do list of home assistant.
