Review on Aqara Water Leak Sensor: Wireless Mini Flood Detector for Alarm System & Smart Home Automation - Works with IFTTT by va Molnr ᠌

The sensor's contacts are in the form of bolts. After unscrewing them and adding plates with wires, I discovered that although there was only one sensor, it had two trigger locations. In order to illustrate my second argument, I will use the example of a point light bulb. The actual cottage can be found below, hidden entirely behind the kitchen set. This area is referred to as the lower level. If you connect it directly, then all you need is a wall between the sensor and the hub, three cabinets of a kitchen set, and another wall, and everything will work!
