Review: Small but very capable door and window sensor for smart home setups - I added this to a smart home setup and it has worked really well so far. It is a compact Bluetooth door and window sensor that detects when something opens or closes and can trigger notifications or automation scenes. Installation was simple. It mounts with adhesive and the sensor and magnet align easily on a door or window frame. Once installed it disappears pretty well visually because the device is small and lightweight. One thing I like about this sensor is that it does more than just detect open and close. It also measures tilt angle and light levels, which opens up some additional automation possibilities depending on how you are using it. Battery life is rated up to around five years using a coin cell battery, which is nice because it means you are not constantly swapping batteries like some sensors. Overall this is a solid little sensor if you are building out a smart home or security setup. It is easy to install, integrates with automation platforms, and gives you reliable notifications whenever a door or window is opened.
Review: Perfect for monitoring Garage Door status in Home Assistant - This little gem is AMAZING! This particular model operates with BLE and instantly integrates with the Bluetooth proxy on home assistant. It has replaced all previous attempts at getting a reliable garage door status (into HA). Now not only do I have an open and close reporting but I also have the door angle showing in dashboard. I never even tried to connect to the shelly app/cloud. It claims to have an encryption option but I don't care about that. Device came with battery pull tab and a fresh battery as shown to be 100% in HA. I don't understand why all the negative reviews. This thing is solid! FWIW, I got the white model.

### ⭐ 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.
