Review: Excellent sensor! - Installed along side a Shelly Gen4 smartswitch to report status of garage door. Works perfectly. Shelly automation products are great quality and app is excellent albeit a bit complicated at first.
Review: Works Great for Me - Using this little bluetooth contact sensor in the mechanical room of my basement, on the lid of my washing machine. It's part of an automation on Home Assistant that ends a "nag" if I haven't removed my wet laundry after a cycle. If the lid is open for greater than 20 seconds, the nag turns off. The lid closes, the nag is reset for the next load. This was very easy to install and it's quite small. In my case, it melds in quite well with my washing machine. Because I have bluetooth proxies everywhere, I have zero connection issues. It was definitely a good value for the money, and enables me to use a non-Zigbee device in a location that sometimes gets Zigbee-cranky.

### ⭐ Defective Sensors
*by M***O on September 13, 2025*

I ordered two door/windows sensors and they both arrived with dead batteries. After replacing the batteries and trying to configure them for over an hour I finally gave up. No help from their costumer service at all. I do not recommend these sensors.
