I have such a problem with fibaro motion sensors. A very simple flow is created. If the sensor detects movement, it is the right time then turn on the lamp at 50% and after 2 minutes turn it off. And in general, the flow works, but after several dozen launches, a strange situation occurs and the lamp turns off after a dozen or so seconds. As if the sensor detected movement and after a while, when it detects movement, because it flashes green again, the lamp turns off. ![Opera Zrzut ekranu_2023-01-13_2153301_my.homey.app](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/5/b594563787aae670e4d0fcbb70aac5b19d3353bd.png) ![Opera Zrzut ekranu_2023-01-13_215251_my.homey.app](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/6/c66305d58d0389208359a812fd18faa8c27921dd.png) ---

This is not gonna work as you want probably: You cannot cancel the 2 minute delay. So when the motion is re-activated, it will still disable the light after the first motion-deactivation. You will need a timer which you can cancel. Take a look at this (importable) flow: > [@The Flow Exchange(r) - Exchange Your Flows with Others!](https://community.homey.app/t/the-flow-exchange-r-exchange-your-flows-with-others/68981/24): > > Motion activated Light/Device, off after a certain time of no motion This flow uses a motion sensor to turn a device (light) on and after 5 minutes (can be adjusted) if no motion, it turns the device off.

Okay: Motion is detected: light is turned on and a delay starts to turn it off. You walk out of motion. Within a minute, you walk into the motion again. The lamp will be turned on (thus: stays on) and another delay is started to turn it off. But after a few seconds, the first delay to turn the light off, will still be executed. A delay cannot be stopped, thats why you need a timer app. So you can cancel a turn-off-“delay” when motion is again detected. ---

Your flow will only do what you want if you walk into a room and out of it immediately. Because everytime the motion is triggered, you will turn the light on and after 2 minutes off, no matter what happens further. And you LOG shows that you tested the motion within those 2 minutes. ---

As Arie said, the flow is restarted with each movement and then the lamp is turned off after 2 minutes each time.

As already mentioned before, the timer will **not reset** or **stop** at all, it will **keep running** no matter if the flow is triggered again. If the flow is triggered, and you trigger it a second or even third time, on the 1 minute en 50 second mark to have your responds as example, it will **turn off** the light because the first flow’s time is **still running** , and thus turn off the light 10 seconds after it was turned on thanks to the 2nd flow trigger. Flow trigger 1 [16:50:00]: Turn on light, start delay Flow trigger 2 [16:51:50]: Turn on light (/stay on), start delay Flow trigger 1 [16:52:00]: Delay runs out: Turn off light Flow trigger 3 [16:53:40]: Turn on light, start delay Flow trigger 2 [16:53:50]: Delay runs out: Turn off light Flow trigger 3 [16:54:40]: Delay runs out: Turn off light (/stay off) ---

Think about using “Zone activation” instead. Use two flows, one for turning on the light when the zone becomes active (sensor senses movement and time is…). Second flow to turn off the light when the zone has been inactive for x time. Works perfect for me. I also use luminance in the mix so that the light only goes on when it is dark enough. ---

And if you want to use timers per se, turn the light on when the motion is detected, and start the timer for turning off the light when the motion is no longer detected. ---

@Damian_Surma I realize that I’m reviving an old post, but I was wondering if you already figured it out, and if you are still having issues with your flows. If so, I recently created a tutorial that should do exactly what you want. see: > [@\[HOW TO\] Gain full control over Zone Activity using Motion Sensors (PIR) and Virtual Motion Triggers](https://community.homey.app/t/how-to-gain-full-control-over-zone-activity-using-motion-sensors-pir-and-virtual-motion-triggers/144082): > > Introduction This is not a guide on how to implement a specific use case, but rather a framework that will give you full control over zone activity. Many flows like turning on/off lights could be done much simpler. However, when my personal flows became more complex, I ran into a lot of caveats and quirks that caused me to rethink how I work with motion sensors. I came up with this system which allowed me to solve all the bugs I ran into and I would like to share it with all of you. The problem…
