I'm a new user - Is it possible to create a flow with When / OR?

Example use case:

When:
Protect sensor
OR:
Aqara camera
detects movement
OR:
Meross sensor detects presence

Then:

What is the best way to achieve this?

Or is this only achieved by choosing the “Zone became active” card?

I assume the zone cards are the best choice because they account for any/all sensors, and if individual components change, the flow will not break.

You are not asking an OR in a condition as that is possible but Multiple Triggers

there is a lot to read (I think everything is already written about that…)

When you want free choice: Only possible with advanced flow
Just connect all triggers to the next card. Either trigger will start the next card:

And yes, some standard /advanced flow cards are to be considered “Any” or “Or” triggers, like “zone becomes active”, which can be activated by different movement/contact sensors in that (sub)zone, or
these cards:

However, these are “all or nothing” like cards.
They’re not available on zone level :man_shrugging:

Yes, that’s a big advantage of zone activity cards.
