I bought two of these sensors. sadly one of them wasn't working. I assume that the reed contact isn't working. lucky me after contacting them and sending a video, I will get a resend. As you can see on the attached pictures these sensors are very small. The Installation is very easy. You can fix the sensor with the included screws or more easily with the also attached double-sided adhesive tape. I'm using these sensor with my FHEM (http://www.fhem.de/) running on a Raspberry Pi 3 Model B and Razberry 2. The inclusion was very easy. After removing the protection "paper" from the battery (which is also included) and turning my home automation system in inclusion mode, the sensor was immediately recognized. The sensor is working fast.
