室内空气质量监测仪，可测 CO2、温度和湿度，支持 Wi-Fi 上的 Matter

I have been using the device for two weeks. Great item. Quiet and thoughtful. There is a multi-colored LED that indicates the air quality. Can be programmed to turn off at night, brightness can be adjusted. There is calibration for temperature and humidity readings. There is a sound siren, which can be switched to silent mode. If you blow on it, the readings suddenly drop by 2k for CO2. It also works fine via WiFi, but it's a pity that only its proprietary protocol and its own app are supported. The disadvantages include the LCD screen and the fact that there is no built-in battery, although the latter is debatable. The battery gives an error to the sensors when charging. I would like to see it on electronic ink for better readability. In general, this is not a fly-by-night operation. This is a really high-quality and well-designed device. The cable is almost three meters long; I have never seen such long cables with any piece of equipment. I recommend it.

I didn't show up in SmartLife app so I downloaded eWelink and all features are working fine. I think the temperatue runs slightly higher than it actually is but there is a calibration feature that a lets you add a contant value to the reading (positive or negative constant). I am still figuring out if the CO2 sensor is off or not, because it never gets down to the 400s, which is what I expect the air outside to be, even after hours with the windows opened. So I still need to bring it to more places and compare. Unfortunately it doesn't have a battery, so it turns off everytime you need to take it some where else.

The sensor seems to work quite accurately; just blow into its openings for a second and the counter jumps above 2500. When I close the windows for a long time, it rises to around 1000, and when I open them again, the counter starts to decrease. It stabilizes at around 550 when I'm in the room, and around 450 when I've been in the room for some time (with the windows open). It works perfectly with Home Assistant, and can be configured in both EWeLink and Home Assistant simultaneously.

A great air quality sensor at an excellent price, delivered in 2 weeks. Can be connected via Matter to different ecosystems, or simply via Wi-Fi in the Ewelink app. The data is displayed accurately. It's convenient that there is multi-connectivity to different ecosystems without resetting the sensor. It's a pity that it doesn't show other air metrics besides CO2, humidity, and temperature, but then the sensor would be more expensive, so no complaints.)

Excellent station. I used it for CO2 monitoring and automation for the greenhouse. The CO2 measurement seems to be direct rather than mathematical. It integrates correctly with Alice via the Matter protocol, with the ability to create scenarios. An interesting feature is that I was able to integrate this monitor with either the official Sonoff EWelink app or Alice via Matter. It cannot work in two programs simultaneously.

Excellent sensor. The Yandex station mini 3 pro connected via Metter. Purchased for the automation of supply and exhaust ventilation in Turkov. CO2 scenarios are working. Not a very successful design with a fold-out stand and no option to mount it on the wall due to the location of the air circulation holes.
