Hugely impressive !
Goods don't cost that kind of money. The readings are kind of normal, but despite the applications for work with Mi Home, this product is not supported in the Xiaomi smart home system. No way. I was never able to start it on the devices, not on the list, not on the search, not on the QR code. It will not be possible to connect it to the ecosystem and configure the scenarios accordingly. And that was the main reason I bought this sensor. So watch yourself. Personally, I'm upset, Yu's going to lose a pretty big amount of money to get just a sensor that you could buy and it's a lot cheaper.
Instructions only in Chinese. However, with English language settings of the device largely self-explanatory. In case of an emergency, use the instructions in YouTube. Thank you
PM2.5 and CO2 sensors show very real values, reacting very quickly to air changes. The device works quickly, has a lot of configuration options, downloads the successful automatically, does not download aqi for our zone, nor does the weather forecast. The screen is readable, the touch works quickly and precisely. It works well with Xiaomi Home and Cleargrass Air applications, enabling automation to be controlled by read data. Looks good, battery's good. hour, I use constantly connected to the USB charger.
