**When…**  
– The motion alarm turned on (IKEA Motion Sensor)  
**And…**  
– Logic card: Brightness (Tag) is less than 20  
**Then…**

How to use _ **Tags** _ in a flow, I suggest to follow [this](https://community.homey.app/t/how-to-use-tags-in-a-flow/9285) tutorial.

To ensure that the light goes off after a certain time, I suggest following [this](https://community.homey.app/t/simple-lights-turning-on-off-based-on-motion/10889) tutorial.
