Two motion sensors to trigger switch?

[JDRoberts]

@TheModernShane

I’m looking for a way to have a switch trigger based on two motion sensors needing to show motion to reduce false negatives. How can I accomplish this?

Yep, Mike maxwell’s excellent zone manager smartapp is designed for exactly this purpose:

Smart Zone motion detector (Zone Motion Manager) [Deprecated -- no longer supported]

I built this to solve a number of motion related issues. –Reduction of false motion events in exterior applications (False Motion Reduction) –Represent a group of detectors with a single virtual detector (Motion Aggregation) –Enable a Motion Aggregation zone from various devices, switches, contacts ect (Triggered Activation) This is a parent/child application (like Smart Lighting) where the motion zones are created and edited from the parent application. When a new virtual zone is created, a virtual motion sensor is created for that zone. This virtual motion detector represents the states of the physical motion detectors that you configured for that zone. You can then use that virtual zone device in any applications that accept motion devices. [image] [image] [image] Three co…
