Review on 🏠 Samsung SmartThings GP-U999SJVLBAA Magnetic Motion Sensor (White) - Advanced Home Security Device, Hygienic Design - 1 Count (Pack of 1) by Kody Bradley

These sensors are good. They're small, the range is good, and they also sense temperature. The best thing about the "magnetic mounting system" is that the magnet is in the sensor, not the base. I was able to install them by finding a drywall screw that was close enough to the surface. The magnet in the device fixes it well to the drywall screw! No tape, no glue, no drilling holes. And I can easily move it if I want! For anyone having connection issues, chances are you have a weekly ZigBee mesh. ZigBee operates at 2.4 GHz and will be interfered with by your WiFi, microwave, etc. - For battery-powered devices, the range is not as advertised. Especially through walls etc. - Battery operated devices do not function as mains repeaters, only mains operated devices. You Don't Expect Your WiFi Signal If you drive 10 million miles, why do you need ZigBee (or Z-Wave) signals? To have problems with. The key is to have enough equipment to create a strong mesh.
