Hi All I am looking for a motion sensor which only triggers when i am crossing it. In my current setup i have installed hue motion sensor right inside my bedroom. The problem is that this sensor triggers also if i walk by outside the room. I would only need some sort of horizontal laserline that triggers alarm when i cross it. Do you guys know some gadgets that works this way? Any help is appreciated šŸ˜Š Cheers, Elijas ---

Try to find other location for sensor. E.g. stick it above the door from inside of the room. ---

Thanks a lot for the link, looks very Interesting. I tried to change the sensorā€˜s position but it triggers too much movement inside the room in that case. ---

Is this unit supported by the homematic app? (Its not listed) ---

For a second time, I apologize. This sensor came to my mind spontaneously during I heard the problem, I did not look into the Homematic-App. I myself have no Homematic devices in use. ---

Maybe some modification to be made to sensor - build shades/walls around a sensor so it detects only movement within visible area? Didnā€™t try this one, but it should workā€¦ ---

Years ago, Fibaro promoted the idea of using 2 motion sensors to achieve a kind of passage control (of course without modifying the sensors). This could not be realized until today. Would be great if someone would get it realized. šŸ‘šŸ¼
