Smartthings motion sensor "no motion"

I have a simple automation that turns a light on with movement and then after 10 minutes of “no motion” turns it off. What I have found is that if there is “motion” during the 10 minutes the the 10 minute timer is not reset and the light goes off 10 minutes after the initial " no motion" ,I have other types of sensors that will give a 10 minute period of " no motion" from the last no motion action , is there anything I can do to the Smartthings sensor to get it to work like this.

Hello, @Graham2306

It depends - how did you create the automation?



Hello AlecM,
I created the automation in the Smarthings app.

Hello - I’m assuming you mean ‘Automations’ in the “new” SmartThings app. (Icon is a circle surrounded by 5 other circles).

I just tested an automation with my Samsung Motion Sensor (bought last year - so recent generation) to turn off a light after two minutes no motion - and it worked perfectly. I kept setting off motion again and again - and then stayed away for two minutes and then the light went off. (So Motion sensor: No motion for 2 minutes).

That’s how yours should be working… sorry, that’s not particularly helpful. Maybe take a look at its Activity istory (go to the sensor, and look at “Activity history” ) and see if it’s actually resetting to “No motion” when you expect it to? Good luck!

Yes that is how I would expect it to work , I have looked at the history and the “motion detected” and “no motion” times are as expected.

Try creating your automation using the Smart Lighting SmartApp. I use that scenario in my garage and it works perfectly.

If you created the rule in the Automation section of the new V3 app the timer DOES NOT reset. It is just that, a timer that counts down to zero. As @HalD said, smart lighting is where you want to create this rule.


Dunno @oldcomputerwiz - I created one and it absolutely resets when another motion happens. Fires exactly x minutes after last reset to no motion, only if no other motion has happened. I tried it a few times (using Automations in new app).

Could it be

  • because I have a V2 hub though using new app? So different behavior on V3 (Though that seems weird).
  • sensor version - mine’s about a year old, though it’s the “new” type - maybe newest version works differently?

Just guessing here.

Anyhow, agree with trying Smart Lighting. Good luck!

Hello, @Graham2306,

Here you’ll find an example of the exact action you want to execute using the Rules API.

Hope this information helps you,

I can get it to work as I want by using an Alexa routine or Smart lighting to turn lights OFF so it must be a bug in v3 Smartthings app.

I’m running into this at a 2nd home of mine so tested it at my home. Only difference is the motion sensor here is a ST. The one at the 2nd is another brand that I pulled over from a wink hub. I’d hazard to guess it’s more an issue with the device handler of the other sensor.
