Multiple Motion Sensors to control one light switch?

[slamam]

I have a long hallway which needs several (3) motion sensors to cover, but the lights are controlled by just one switch.

I would like for the lights to turn on when motion is sensed by any of the sensors, and turn off when there is no motion on all of the sensors.

The smart lights app will allow me to turn the light on using all three sensors, but does execute the turn off function as I would like. The turn off function is only determined by the switch that turned on the light. For example, if I enter the hallway and trigger ‘motion sensor 1’ to turn on the light, then walk down the hall (and remain by ‘motion sensor 2’), the light will turn off when no motion is sensed by ‘motion sensor 1’ (even though ‘motion sensor 2’ still detects me).

Any help or recommendations would be greatly appreciated.

Thanks

Try this…

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…

Works really well

If you haven’t used custom code before, it’s pretty straightforward. Basically you will copy the author’s code and paste it into your own account. Here’s the FAQ for that process:

FAQ: An Overview of Using Custom Code in SmartThings (SmartThings Classic, Groovy Code)

So you’re new to SmartThings, you asked a question, and someone suggested “custom code” as an answer. Or you were browsing the forums, and you found something that sounded like it would be perfect for what you wanted, but again, “uses custom code.” What does that mean, how hard is it to do, and what’s the difference between a “SmartApp” and a “Device Type Handler”? (Note: the official terminology has changed a couple of times. “device type handler,” “device handler,” “DTH,” and “device type” all mean the same thing, and you will find all these terms used in the forums.) SECTION I: SMARTAPPS AND DEVICE HANDLERS: WHAT THEY ARE SmartAPPS: Tiny Programs to decide what a specific device should do when, or to collect the information from a specific device SmartApps, including the various f…

Any help or recommendations would be greatly appreciated.

It’s all about WebCoRE! That’s what you need and once you do you will never go back to using Routines or Smart Lighting

Your requirements were similar to mine , so here’s a Piston I previously created for two motion sensors and one light / smart plug. Once you install and get everything up and running, you can restore this Piston with the 4 digit code and replace it with your own motion sensors and light. Then of course qualifications can be changed as I only have mine work between Sunset and Sunrise.

Also a new video was just created to walk users through installing webCoRE

Thank you so much for the help! The Zone motion manager is exactly what I was looking for!

Well almost exactly what I needed.

The lowest value for Motion Aggregation was one minute, so I changed line 308 to give a 1 second update interval.

This works perfectly, my light turns on when any sensor is triggered (through the native ST app) and turns off when all sensors are inactive (via Zone Motion Manager).

WB70, thanks for your advice on WebCoRE. I have heard about WebCoRE, but have no coding experience and am still trying to keep things simple. Once I have the basics down, I may expand my horizons and try out some pistons.

Thanks again!
