## Description

Xiaomi Capteur Intelligent Mi Door and Window Sensor 2 OB02751 Noir : desertcart.co.uk: Computers & Accessories

Review: Small and excellent addition to home assistant - I was surprised by the size of the device when I received it, it is a lot smaller than expected. First device I received appeared to have a connection problem with the battery, but the replacement I received worked straight away. I use this to monitor door openings via home assistant, and it was very easy to set up. It has both light detection (albeit quite rudamentary, it won't do lux readings but says simply light or dim) and contact sensor. Signal is good from it, it is able to hit my bluetooth gateway without a problem.
Review: A good companion for my Home Assistant system - Work well with my Home Assistant system.

### ⭐⭐⭐⭐⭐ Review
*by D***R on 30 April 2023*

Die Sensoren funktionieren ohne Probleme. Einziger Nachteil für manche könnte sein, dass sie nur Bluetooth können. Da ich auch Shelly in Verwendung habe, lasse ich die Shelly als Bluetooth Gateway laufen und habe diese Sensoren darüber in meine Home Assistant Installation eingebunden. Sensoren machen ansonsten was sie sollen. Sehr gutes Produkt, relativ klein und unauffällig.
