Qingping Air Quality Monitor Lite with Wi-Fi, Supports HomeKit, Detects PM2.5, PM10, CO2, Temperature and Humidity, Tests Indoor Air Pollution with Accurate Measurement

Dyson tp09 and this gives almost the same reading.

Amazingi have connected it to type c cable it shows me aqi of my room

The device looks sleek, and its PM2.5 / PM10 readings broadly matches nearby public air-quality measurements. Unfortunately, that’s where the positives end. Both the humidity and temperature readings are grossly off when cross-checked against other devices and online data sources. Even more disappointing is the software: for a product at this price point, it’s surprisingly buggy and lacks basic functionality such as displaying historical data. Customer support is slow: it's taking days to respond and provides only generic suggestions like “please restart your device,” none of which resolved my issues. Clearly not recommended!

Does not show pm2.5 or pm 10 No catalog available Poor quality product Do not recommend at all Product details are misleading

I got it after long research, Qingping were recommended for precision back then, I am happy with it. Easy to setup and use. Only works around 20-30 minutes unplugged but long enough to calibrate it outside.

Lo stiamo testasndo da un paio di settimane per tenere sotto controllo l'inquinamento in casa, e sembra funzioni. L'estetica è piacevole e bella e la ricarica USB molto semplice.

I was in the market for something HomeKit compatible to replace the two different devices I was using to monitor air quality and to consolidate them into one .I was a little bit hesitant to order because the reviews were a bit mixed but the moment I opened the package I was very very happy. The initial impression is very good and when I plugged it in, it started working right away and within a short time the values were reasonably consistent with other similar devices I have. At first, it wouldn’t pair with HomeKit but I followed the instructions to reset the network settings and the pairing went perfectly the second time. Since then, it has worked flawlessly. I love the Homekit integration and the ability to use Siri to query for the different values. The only thing I think which could be improved is the native app for the device. It works fine but it’s a bit bare-bones and not very visually appealing. Other than that, I am thrilled with the purchase.

Funciona perfecto y se configura en 1 minuto ademas tiene batería, aunque creo que esta diseñado para estar conectado.

EDIT 11 months after purchase: About 10 days ago you can see the temps slowly starting to rise. It became warm to the touch, and it seems obvious that the internal fan has failed. I've set a temp offset of -10 degrees to correct the reading, but the warmth worries me and it's not trivial to disassemble and fix according to the teardowns online. A shame - otherwise a very nice little gizmo. It's small, quiet, and seems quite accurate - comparing to Ambient Weather AQIN and Hydrofarm APCEM2 Autopilot, CO2 readings are consistent. Setup was easy (iOS and Apple Home), and it's just a delightful little gizmo, so cute! Small annoyances: No Alexa or Google Home integration (yet, I hope! QingPing, make this thing work with Alexa and it would be perfect!), and "screen saver" display is a little too much motion for something that sits on your desk, it's a little distracting. I've positioned it behind a monitor in a way so that I have to move my head a little to see it. Overall I'm very pleased with this purchase.
