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

The media could not be loaded. 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.

It's super compact so great for travel and moving around with to test air quality. One of my minor problems with it is that it currently lists the temperature in celsius instead of fahrenheit. It's not that big of an issue, we lived abroad so I got used to the temperature being in celsius. But now that we're back in the states, it might be easier to just see what it currently says in fahrenheit.There may be a fix for it that I haven't found yet, or tried. But a simple 'hack' I learned that gives you pretty accurate C --> F conversion was to just double the C and then add 30. So if it's 30 C, double it is 60, then add 30, so it's about 90F.

I bought a couple of these and would have bought more if they were able to connect to my Apple Home system but both monitors refuse to do anything but fail to connect using a current iPhone and iPad.I have 84 devices in my Apple Home system but these won't join. You shouldn't have to give up your phone number and email to get a product to work.They are nice stand alone monitors but the display is pretty small.

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!

Two Stars for Two Years. This worked perfectly for two years. I had it connected to HomeKit and it sent me readings everyday. Now it won’t connect to HomeKit and the fan inside makes noise.

I have a small home office that doesn't get great airflow and was concerned about the CO2. This device is super responsive and now I can easily monitor CO2, temp, humidity and AirQuality. I like the looks and with HomeKit I set up automations to automatically turn on a vent fan if CO2 gets too high. I also have it setup to turn off my space heater when the room warms up. USB C is great for keeping it charged. I'm thinking of getting a few more to replace battery operated temp/humidity sensors in my house.

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.
