@xCite86 Ah, that’s the way ruling works. A rule get’s only triggered when item in the IF clause changes (trigger) where I thought they were evaluated in a loop again and again.
In that case it should not be possible that my original rule evaluates twice on just one PIR activation as I noticed: two emails in 5 seconds where the PIR was still on from the original detection. This means in my situation I should not need a check on double emails on one PIR activation.
Something else is wrong then.
Thanks for clearing this for me.
