Hi all,
I have an automation scenario i want to implement. It looks fairly simple, but i cannot find a way to do it (i have rule machine installed, btw).
Let’s say i have two motion sensors, A and B.
I want to trigger an action if A detects motion only if B has not detected motion for the last x seconds.
Is there a way to achieve this?
Thank you all in advance.
I think it’s called a conditional trigger in RM terminology.
It sounds like you are trying to aggregate two motion sensors together, @Mike_Maxwell has a zone motion device type just for that.
Zone motion manager can detect this, it’s noticed as a false motion event within the false motion reduction zone type, however it doesn’t emit this an an event.
You could easily track down the location of this log message, add a line to send an alarm event to the modified virtual motion detector, and off you go from there.
Thanks a lot for getting back. Problem is, I am not a dev. 
I will try to look into it.
