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