is not suitable for a smart home, if there is an agar gateway you can buy. Alert works on agar. At night, wake up with a flood)))

Pros below: Small and invisible. Battery up to 2 years. You can extend the contacts with a wire and bring them anywhere. Different cons: Does not enter pairing mode. As soon as you release the button it stops blinking.

I did not immediately connect to mijia gateway 3 due to the fact that the application uses the 2022 region. But the hack helps with connecting not through the application, but by pressing the button on the gateway itself. Sometimes it is necessary to reboot the gateway before connecting such a sensor. Different pros: Works correctly, works quickly enough when water appears under the contacts Cons below: A weak signal, when placed in sanitary niches and boxes, may lose contact with the gateway…

Got pros: As part of the AQARA system, the sensor works. I had to install an additional smart socket in the basement of the house to amplify the signal. Cons below: Small size. You can easily roll it under the bathtub due to inaccuracy, since the sensor lies on the floor.

I made my own (local) smart home, without Chinese servers. Like the rest of the Xiaomi smart home sensors, it works great.

Mi Home does not see this sensor and you can connect only using a special mode manually, alternately holding the buttons on the station and the sensor. At the same time, if you overdo it, you can reboot the station itself) It is possible that Akara will connect to the Hub immediately and regularly, but it does not connect with Xiaomi without witchcraft) Otherwise, after connecting, everything works well. I hope it will not come in handy, but God saves the safe!

For the experiment, I ordered the CN version, although in the reviews they wrote that it works in the 2022 region . As a result, we have - Aqara Home sees the device and even adds the CN version to the 2022 region without problems. Automatically appears in UDYA. In Home Assistant, it also pulls up automatically. The test for operation with water passes perfectly.

I will explain how to quickly connect the sensor for those who use the Aqara (HomeKit) smart home. To connect, you need to open the box and place the sensor in the room where you plan to use it (although the room and location of the sensor can be changed later in the DOM application). Perform 5 quick button presses on your hub (I have Aqara-hub-M1S) to put it into search mode. After the hub “gurgles” (after 5 seconds) about searching for devices, go to the leakage sensor, press the “droplet” on

We have these sensors in the bathroom and in the kitchen (we have a washing machine there). Of course, we sometimes check them, they work quickly. These days they cost a penny and at the same time there were no difficulties during installation, even tools were not needed. In addition, we connected Aqara Hub to the base (we also have sweethearts and switches from them), as it is much more convenient.

We have a "smart home" system installed in our apartment, we connect the smart devices we need to the Akara Hub base. A water leak sensor was installed about a month ago. Immediately during the repair, they did not think about it, and during the breakdown of the washing machine, the neighbors from below were flooded. Now, in the event of a flood, we will be instantly informed and will be able to respond promptly. A very useful thing.

Has pros: It works 100%, connected to the Geteway 3 Xiaomi gateway in the gateway menu itself in third-party devices. Works great in Mi home smart home environment. Cons: It was not possible to connect the first time, but figured it out after reading the reviews.
