Qingping Air Monitor Lite, Apple HomeKit Compatible Wi-Fi Indoor Air Quality Meter Detects Home CO2, PM2.5, PM10, Temperature, and Humidity

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.

Overall, I am pretty happy with this air quality sensor. I cannot speak to how precisely calibrated it is, but it has still been very useful in practice. I have been able to get my room down to zero PM2.5, and having visibility into particulate levels has been reassuring. The CO2 and humidity tracking have been especially helpful. I noticed my clothes were not drying properly, which I probably would have ignored in the past, but the sensor showed humidity around 80 percent, which explained the issue immediately. I was also surprised by how high CO2 levels were getting in my room. I had been focused on air quality but not really thinking about CO2 buildup. With the door closed overnight, I saw CO2 levels climbing close to 2,000 ppm. When my girlfriend is in the room as well, it has gone over 3,000 ppm, which is clearly not ideal. That insight alone has changed my behavior. I now keep the window cracked open two to three inches instead of just a tiny gap, even when it is cold, and it has made a noticeable difference. My only real complaint is charging reliability. Occasionally it seems like it is not charging and will turn off. Unplugging and plugging it back in usually fixes the issue, and it does show that it is charging afterward. I am hoping this is just a minor quirk or user error, but it is something to be aware of. Despite that, this sensor has been very helpful in understanding my indoor environment and making practical changes to improve air quality and ventilation.

Even though the device looks nice and has nice screen, but readings are not accurate. Temperature readings are not accurate at all, and I wonder if other readings are way off too. You cannot change device settings (screen saver, C/F, etc) unless you connect the device to your Wi-Fi network (potentially providing manufacturer your Wi-Fi credentials), you need to download their app, and create an account!!! Also device constantly sends some data to Chinese servers, and if you disconnect the device from the network and remove it from the app - all settings will be restored to default settings. So they basically are forcing you to have an account and keep device connected to the network, so they can harvest your data (and who knows what exactly they are harvesting??) and send it to China.

Great product. Does the work done

I purchased three of these for use in different rooms. Two of the three had visibly been opened despite being sold as new by the Qingping store. There were a couple of hairs under the protective temporary film for one of them, and two were missing the smaller of the two pieces of temporary protective film that covers the back of the unit. Two were also already configured for somebody else's wi-fi network. The idea of a multi-sensor HomeKit appliance with a big OLED display sounds so good. But the execution is flawed. 1. It fails at its most important task: Providing accurate readings. The humidity reading is consistently off compared to the three other humidity meters I have. I can line them all up and the QingPing always has anomalous readings by as much as 15%. The temperature reading is off, but only by a couple of degrees. I don't know how to assess the CO2 accuracy, but I have seen it as low as 418, which is about the ambient CO2 level in all rural areas. 2. The display is wasted. It has different views, but nothing that shows all readings at once. You have to cycle through manually, or configure it for automatic cycling. There's enough display density that it could have shown everything. With single readings, a boxy, thin, LCD-like font is used that makes it difficult to view at a distance despite the bright display. 3. The HomeKit integration is half-baked. Enabling HomeKit mode disables all of the configuration options. For example, the display cannot be changed from Celsius to Fahrenheit. Notifications can't be enabled. The app can't even show graph results. To take advantage of the app features, the device must be reset and configured for QingPing's proprietary mode, which disables HomeKit. 4. The app support is confusing. It links to two different apps in the manual, the first of which doesn't appear to link with the device in the USA. The second is flakey, routinely forgetting about registered devices, or not finding them on the network. Unfortunately, I don't know of another product that claims to have all of these sensors along with HomeKit compatibility. For now, the alternative is having at least two other devices, or going without either the CO2 or the PM2.5 and PM5 readings.

I've bought two of these units recently to place in my living room and bedroom. Both units required calibration for RH, and after CO2 calibration one was reading 8% higher than the other. But after adjusting the calibration offset in the app, both are giving the same readings consistently. I like that all of the sensors can be calibrated to known sources, and the CO2 sensor can be manually or automatically calibrated. You can also do firmware updates and customize just about every possible setting and configuration in the app, as well as track trends and get notifications for sensor data if you'd like. The only thing I wish could be more customized is maybe the screen saver so I could choose which data it rotates through rather than having to choose between all of the data or just one data point. Overall I am really liking this unit. It's small and easily placed just about anywhere, the app is great once you play around with it a bit, and being able to look in on your monitors when you're away from home is great. Keep up the great work Qingping!

I really love having this around, but it’s very bright at night and there’s no way to control the screen display state in HomeKit = 3 stars for me. I would rate it 1 or 2 stars bc I'm upset at the lack of basic controls for the built-in display, but I am trying to balance the pros and cons in my reviews, and, overall, I would say I am actually pretty happy with the little device. Knowing the air quality and CO2 levels has been a game changer in my bedroom. I recently discovered that if I leave my bedroom’s door closed for an hour with my house’s AC off and windows closed, the CO2 level rises to almost 1500 within an hour! It’s such a quality of life improvement to know if my tiredness is just because I’m tired or because I haven’t opened my window in too long. It just feels so much better to know. Super worth it purchase for that peace of mind alone. That being said, you can buy other CO2 monitors for much cheaper, so let’s talk about the standout feature here: HomeKit. How does it interface and what can you control? Setting it up was pretty nice. I didn't have to download a 3rd party app or anything, just went straight into the Home app on iOS. (I did eventually download their app though, because it has some nice features actually, and when I did, the sensor was automatically detected. Didn't have to re-add it to the app or anything). Each sensor feeds data to my room's status. HomeKit doesn't give exact values for everything, so be aware of that. Right now, I see: Temperature: 70°, Humidity: 46%, Air Quality: Excellent (if you tap to expand the menu for Air Quality, it shows you the actual readings from the PM2.5 & PM10 sensors in μg/m^3), and Carbon Dioxide: Sensor (idk why, but it literally just says "Sensor" under the Carbon Dioxide status in HomeKit. Likely an Apple thing). If you open the CO2 sensor page, it will show you the reading in ppm though as well as a "detected" status, which I presume activates over a certain reading. In each of the menus associated with the sensor, it also shows you the Battery Level, Charging (status), and Status Active. SO, it has lots of outputs feeding to HomeKit, but what are its HomeKit smart home inputs? Can you use HomeKit to change which reading is displaying on the sensor's built-in display? Can you use HomeKit to turn off the display (for example with an automantion that activates when you leave your house or turn off all your lights)? Can you change the brightness of the display? Turn the device on or off?.... No. You can't control anything on the device from HomeKit. It's only an output machine. I would be totally fine with that if there was ANY way to adjust the built-in display's brightness, but you cannot (not even in their QingPing app). It's super bright at night, which is pretty annoying. It is possible to use the QingPing+ app to program a time range to turn off the display, so I have it turn off just before my usual bed time and just before I wake up. But I don't go to sleep or wake up at the exact same minute every day, so I find myself frequently both 1) checking a black display bc it's off AND 2) being woken up at 6 am on the weekends to a bright display. That being said, these are all things that SHOULD be possible to implement with a software update, so if any of these features get added, I'll definitely come back here and change my review right away. (if you are the developer, PLEASE implement these features!) I have no comments on it’s accuracy because I have no way to double check it’s readings, but to me it doesn’t matter too much as long as it’s giving me generally useful information. So, in summary, it's great to have the data & HomeKit integration, but the display needs to have more controls.

--UPDATE: For some reason it is working again, so something was temporarily wrong, and I upped the stars. Aside from that glitch, the device is good, and gives good readings. Well reviewed by those who tested its accuracy. I bought this just 4 months ago, and it suddenly could not connect to wifi for the app to work. it may be the app or the hardware, but others have complained about this. If you cannot connect, you are prompted to update firmware, restart, restart phone. Nothing works, so it may be that the wifi on the device is faulty. It does work and gives good information. But if you want detailed graphs you need the app. I would avoid.

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.

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".

Sensitive, decent mobile phone app. Bought it as we have two wood stoves in our 1875 farm house. Don't bother using it on battery except for quite tests in other rooms, you need USB power. Easy to setup on home wifi through mobile app. Very sensitive, and was glad to discover the air quality despite the stoves is on average well within Canadian government standards.

リモートワークをしているので、集中できる環境づくりの一環として購入しました。 普段は600代で、ガスコンロを使い出すと1000を超えてきました。ガスを消すと自然に落ち着いてきます。換気扇をつけても二酸化炭素濃度にはあまり影響がなさそうです。 このようなことが分かるようになったので、少し高いですが買って損はないと思っています。

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