qingping Air Monitor Lite, Indoor Wi-Fi Air Quality Meter Compatible with Apple Homekit Detects Co2, Pm2.5, Pm10, Temperature and Humidity at Home

Pros: Sleek device design, minimalistic dashboards, well built product., works well overall Cons: Rarely loses sync and it is practical to have constantly on power since battery won't last more than a day

It is a high-quality product. It doesn't work with the Xiaomi app—unless you change your location setting to China—but I installed the Qingping app, and it works very well. It’s a well-made device; the sensors provide accurate readings. I also have an Inkbird IAM-T2, and the CO2 readings match, but this unit features a small built-in fan that draws in air, allowing for much more precise measurements—including for PM 2.5 and PM 10. One drawback—though I was already aware of it—is that it must remain plugged in (it uses USB-C); I’m not sure how long the battery lasts, but there is a setting that puts the device into sleep mode if it’s unplugged. I highly recommend it for its build quality and finish. While the Qingping app isn't as versatile as the Xiaomi one, it still gets the job done.

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.

It connected easily to my Apple home. And it gives a good flow of data. But you need to use the app to get historical data. The battery life is completely negligible… It may help you get a single reading in a remote situation unless you have a battery pack but using it indoors plugged in it’s great especially to monitor the CO2 levels in my tiny apartment.

If Apple made Air Quality monitor, this would be it. It's really pretty, looks great in the room, it's easy to read with large, bright display and easy to understand thanks to LED indicator light which goes from blue through green, orange, red and purple. Display and HomeKit data refresh every second. It may not seem like much of importance, but presumably you need this to monitor air in your home and to help you develop good habits, like opening a window once in a while etc. Well there's nothing more satisfying like watching CO2 level going down in a real time after doing so. Device has build-in battery but only for about 6 hours of operation, so it's not really a 100% wireless device, you de facto want to keep it plugged in. It has a little fan inside to suck air in and out for sampling, which is quite rare in similar devices. Fan is extremely quiet and I can't hear it, even though I have one of those devices right next to my bed. The QingPing+ app is easy to use, looks good and shows data for the past 24 hours in 15-minute blocks as well as max and min values for each of the last 30 days. You can also download 15-minute data for the past 60 days within the app. It would be nice if the device allowed for more than one value to be displayed at the time (I was told by the developer that this is in works) as well as to allow for LED indicator to display different metric from the main display (for example light to indicate CO2 levels, but display to show temperature). I also noticed slight discrepancy in temperature and humidity readings with another similar devices, but can't really tell with 100% which one is more accurate. Would be nice to have offset option for those readings. CO2 levels seem to be on pair within small margin with Netatmo air monitor, so I believe they're being accurate. Good: - looks great - HomeKit compatible - frequent data read Bad - only single metric on the screen at the time - no way to calibrate/offset temperature or humidity - LED indicator shows level of metric displayed on the screen: there's no way to separate the two to indicate different metrics - temperature threshold somewhat surprising: anything below 23 C is considered "slightly low".

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.
