Rule based on Motion Sensors - working intermittently

Hi

I have two motion sensors in my attic office. I am trying to set up a rule that if both of them don't detect motion, the rule waits 3 minutes, rechecks that both sensors are still inactive (no motion) and then runs a series of instructions to switch things off. I have built the rule pictured below but sometimes it doesn't fire. Any ideas why? Or is there a better way of writing this rule?

Thanks

Before I work out why you may be seeing issues in the rule, you may want to look at the Zone Motion built-in app, allowing you to combine motion from 2 or more sensors into one "device".

Separate to Zone Motion, I think you want to:

  • Remove the predicate
  • Trigger on sensor a "changed" OR sensor B "changed" (two separate triggers)
  • Actions: Add an action to Cancel Delayed Actions for this Rule
    Leave the Existing IF Condition (Sensor A inactive and Sensor B inactive)
    Make the 10 second Delay "Cancellable", maybe even remove the delay and change the Off action to be delayed by 10 seconds... Cancellable...

Awesome - set up a zone and changed the rule as shown below. So far it has worked every time.
