Probably the Xiaomi engineers looked at my review of the sensor's opening in the water leak sensor and decided to make a separate sensor. Let's take a closer look at it.
On the reverse side, the technical characteristics are traditionally specified, from which it is necessary to allocate the basic-size 50 mm in diameter and 15 mm in height, the protocol ZigBee-Naturally, power CR2032 and work at temperatures-10 + 55 C and humidity from 0 to 100%.
Let's go to the content. Externally, the sensor is most reminiscent of the Xiaomi wireless switch
-only with a drop at the back are two pins-to determine the flooding and battery compartment
The CR2032 battery is hidden behind the screw cap, with a rubberized cap. Software
Connection is a standard method, through the gateway management plug-in, the Device tab. The sensor is not only outwardly resembles a button-it contains it, just under the droplet. This is the pairing button, which should be pressed for 5 seconds until the blue led flashes, which is not visible under the top layer.
A separate plug-in sensor does not have-there is only a page management with tabbed list of scripts and log positives. In the upper right corner there is a button with...-Additional settings. There you can turn on and off the option Tandem Gateway Alarm-the same is available and the smoke detector, if it is active, when the water sensor is triggered alarm on the gateway, which controls it. General Setting-Standard options for renaming, location and adding icons to the desktop.
In scenarios, a sensor can serve as a condition and has two options for action — in Chinese. The first is leak detection, and the second is fixed.
As a test-I set the first condition-the inclusion of a light bulb RGBW-red color and notification on the phone, and the second condition-the inclusion of a light bulb in green color. Test
For the test I put the water sensor
in the tank with water-the time of the script is almost instantaneous, you can see in my video review, which will be at the end of the text. After getting into the water-the light bulb was turned on in red light mode, and the phone came push notification. By default, the Tandem gateway Alarm option is enabled, and the gateway is activated in siren mode.
After the sensor is removed from the water and wiped-the second scenario-the elimination of leakage-in my example-turns on the light bulb in green mode. Output
Comparing with my self-made, this sensor does not need to be refined, it is not afraid of pouring water, no wires. At the price-the usual price of it is more expensive, but the sale can be caught in principle for the same money.
As for its usefulness-it is, in time to learn about the leak-will help you to save a great cost of repair, and installing managed taps for water input-and avoid it at all.
