Hi i have a few simple flows that control my lights, but they have a life of their own. Some times they work - some times they dont. And i cant see why. The flows i like this. if there is motion and the time i between 23-06 then dim lights to 20% else dim to 100% and set at timer to 360 sec - after this a different flow turns off the lights when the timer hits 0. I have been using Hue sensors (3 units) and hue bulps. On the sensor i can see the led indicating motion lights up but the lights does not turn on - other times it does. I have added a card that animates the led ring on Homey to see i the flow is running - it is not always the case. So the problem must be with the sensors it seems, so i have gotten new Xiaomi Aqara sensors and replaced my Hue sensors - sadly the result is the same. The new sensors register motion but the flow is not activated. As of now the hue sensors i back together with the Xiaomi to see if a greater number of sensors can force Homey to react - it does not seem to be the case… I use two flows to control the lights in this part of my house because of the layout - one sensor can not cover i all. So sensor 1 activates flow 1, and sensor 2 activates flow 2 - the flows are the same. Distance to the sensors i between 15 cm to 3 meters so range cant be an issue can anyone tell med what is going on before i go crazy ? ---

Could you share the flow and post it here? ---

It seems to be OK. Try to look in insights how are the Homey resources used. Another option is to put some delays on each of the bulb. ---

but how will a delay help when Homey does not runs the flow even when motion is shown on “properties” tab on the sensors. I dont quite know what to look for in insights, but Homey only uses 511 mb of memory and almost no power ---

It should work as you made it, but maybe there is a problem with the card that you use and the way you use it: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/a/9a33e8198975c13b5236f353de1bb25713224e23.png) Can you try to change it into “The time is between 06:00 and 22:40”, should do the same but there is no “day-crossing”. Think it’s worth trying. ---

Try making [this flows](https://community.homey.app/t/simple-lights-turning-on-off-based-on-motion/10889) and see what happens. ---

I have tried with "The time is between 06:00 and 22:40 " and even with leaving it out completely. It still does not work everytime
