Xiaomi Mijia MCCGQ02HL Review

New smart Door Window Sensor 2 from Xiaomi.

Today we will consider a new sensor for opening doors and windows Xiaomi MCCGQ02HL Window Door Sensor 2. It will be connected to the smart home system using a Bluetooth gateway, for example Xiaomi Mijia Gateway, which supports Bluetooth, Zigbee, Wi-Fi, or any other gateway which can be for example, a smart camera, or a socket with a Bluetooth gateway, or a ceiling lamp. Thus, in order to have access to this opening sensor using an application from anywhere in the world and to work in smart home automation and perform various scenarios, any of the above Bluetooth gateways is required.

A gateway is needed to connect the sensor to your Wi-Fi network and vice versa, this, in turn, is needed to implement remote control of smart home systems via Mi Home and receive notifications on a smartphone about various changes in sensor trigger positions.


In the box

The sensor comes in a small white box with the Xiaomi logo. There is also an image of the sensor itself on the front.


On the back of the box are the characteristics of the device as usual. They did not forget about the indication of the ZigBee protocol, with the help of which the device is interfaced with the gateway.

In the kit, on a small spacer, there are two contact sensors operating on the principle of electromechanical commutation, that is, from the presence and absence of a magnetic field in the closed circuit.

Also included is a slightly informative instruction in Chinese and an additional double-sided 3M tape.

Design and construction

The main body of the sensor now has a button, rather than a paper clip hole, and an integrated light sensor. At the same time, it is convenient to press and hold the button during pairing due to its sufficient size, compared to a similar Aqara sensor. On the lower edge there is a hole for opening the sensor. A CR2032 battery is installed under the cover.


On one of the sides of the main part there is a mark for alignment with the contact part, which also has a risk on one of the sides. However, since the magnetic field propagates in a circle on the contact, this risk part is advisory and it can be placed in any position relative to the main part.


On the front, on the main part of the sensor, you can see the light sensor indicator, which turns on and off when it is not paired with the counterpart of the sensor. The surfaces of the main and contact parts in front are completely flat, this advantageously allows them to be placed in any position in relation to each other without combining at risk. The sensors are practically rectangular in shape with the exception of small rounded corners.



In use

Let's proceed to configuring the sensor and pairing it with the gateway. Download and open the Mi Home application, go to the gateway device, within the gateway plugin, go to the Devise tab, then click on "+" Add Subdevice.


In the window that opens, we see all the sensors that can be connected to the gateway, scroll down and click on the “Mi Door and Window Sensor 2” sensor. After that, the pairing window will appear, where it will be indicated that to pair the sensor, you need to hold down the button on the sensor for three seconds until the blue indicator blinks.

Then a window will appear where you need to select the room of its location and what the opening sensor is installed on (door, window, other) and click on the next step. After that, several pictures will appear, which show under what installation conditions the sensor will not work. We skip this window and find ourselves in the devices tab with the sensor that appears in it. Next, you can customize the scripts.

The following options are available in the sensor setup menu. The first point is detecting darkness or light. The second point is timeout detection - when you opened a door or window and then did not close it again, after a certain specified period of time, a notification will come. In the alert settings, you can set a timeout for any time up to five minutes.


Now let's try to go into automation and see what events are available for our sensor. There are 5 events available: dark, light, open, closed and open timeout.

For example, if it gets dark, then turn on the light bulb in the hallway. Then you can add one more event and simultaneously fulfill 2 conditions: if it is dark and the opening sensor is triggered at the same time, then turn on the light. Let's say you open the door to the hallway when it's dark. At the same time, 2 events happened and the automation worked - the light in the hallway turned on. In this case, the notification rate is less than two seconds.


Another variant of the event, let's say you opened the door and forgot to close, then a notification will come to your phone. you can configure that you forgot to close the door or window when the timeout was reached.



Conclusion

The advantage of the updated version of the opening sensor MCCGQ02HL in comparison with the previous versions of the opening sensors is the presence of a built-in light sensor. that is, there is no need to separately install a light sensor or a motion sensor with a built-in light module, but you can flexibly configure automation with just one new opening sensor.
