Event Bus Question

[zisco (Markus)]

Sorry for my possibly stupid question, but can I also transfer the status change of an item (e.g. bulb off) triggered by an external app (e.g. google home) to the openHAB event
bus to react on it? And if yes, are there examples on how to do that?

Item state changes automatically appear on the OH event bus.

@zisco

to react on it?

Use a rule trigger like

when
   myItem changed

I think there must be more to your question. Is there actually an Item state change involved here?

If I understand the question, then this should happen already. Either the binding will see that the light turned off (from what ever means) and update the OH Item accordingly, or you’ve integrated OH with Google Home in which case Google Home is commanding your openHAB Item, not the light itself directly.

Thanks - it works now (it’s good to use the right item…)
