Temtop M10+ Air Quality Monitor Indoor, 6-in-1 CO2, PM2.5, VOC Detection, Smart Temperature & Humidity Sensor, with App Connectivity for Home Air Quality Testing & Analysis

Okay, this this is very easy to use, bluetooth came online and set the time for me, and all readings were available without connecting to my phone, so no need to worry about yet another app to deal with if you don't want to go that route.I'm kind of psyched to have an air quality monitor on my desk, I want to know principally whether my room has too much CO2 in it. I'm under the impression that smaller offices need to be aired out more often than I previously thought, and I'd like to measure that. So far so good! My office has a higher CO2 reading than anything else and my suspicions are thus far justified.Something I'm a little concerned about though is the temp reading on this. I need to get another thermometer to check it, but I think the temperature reading is a little high, which causes me to question some of the other readings as well; I would have thought that the temperature would the be easiest of the four to get right, and if they can't nail that one, what are they really doing?That said however, you can calibrate the temp to another reading if you have that. My thermostat on the wall is all over the place, but I can set the thermometer on the device to match my thermostat very easily with in-app calibration. So if you do know that yours is off for some reason, you can fix that in a heartbeat.Overall, very, very impressed. This thing is incredibly slick and I'm hoping it keeps me just a little more present when I'm in my office huffing my own fumes.

The tech is very impressive. It uses E-ink tech, not a screen, so it can be hard to read under dim lights but otherwise is super cool. It not only can tell air quality, temp, and humidity but it also has a clock as well.Easy to set up and worked right out the box. Took around 10 minutes to calibrate. However if you move it to a new room, it can take 1-2 hours to re-calibrate depending on the temperature difference. It calibrates very slowly. For example I moved it from a very hot upstairs (31C) to an A/C'd room (23.5C) and it took almost 2 hours to slowly get to the right temp.As far as accuracy goes, it seems fairly accurate. I put it next to my Ecobee unit and it was off by 0.4C. The humidity was off by about 8% though. You can manually fix this on the phone app if the difference is too big. The only big error was the CO2 reading....it was in the red and showed over 1,500 but I asked it to re-calibrate on the phone app and it fixed itself.It does not display TVOC, CO2, AQI, PM2.5 all at once. It will only display a single air quality results at a time. You can choose to have your preferred air quality test always displayed or cycle through each one. You don't need the app to do this.The graphs that come with the app is neat, showing you the changes throughout the day.The battery life is very long (30 days) and easily rechargeable via usb-C.So despite it's impressive tech, it's hard to recommend for the following reasons:- Very pricey for a temp/air quality device. For over $200, you can get a air purifier that can do all the readings as well as filter the air. Or off-line devices that has all the same readings for less than half the price.- It only has bluetooth. You cannot remote monitor with this as there is no wifi/internet connectivity. The bluetooth automatically turns off when not in use (Most likely to save battery). Each time you open the app, you will need to manually turn the bluetooth on by pressing the bluetooth button on the device.- You are required to make an account to use the app. And it is not a "create with G+/FB/etc.", you need to manually make an account and password.- An account is required for a fair amount of features. This includes changing from Fahrenheit (default) to Celsius. Re-calibrating, turning off sound alarms, manual adjustments to calibrations, etc.- This is currently the most expensive model from the seller but it is also oddly missing features from cheaper models. For example, the cheaper models have HCHO monitoring and WiFi for remote access. Yet this is significantly more expensive but does not have those features.Overall it is a neat and great device. It is hard for me to justify based on the price. If you just need temp/humidity monitoring, there are basic devices for around $10-$20 and works about the same. If you need air quality monitor, there are air purifiers that can do it (Albeit takes more space). Chances are if you need a small device to monitor the air quality, you would want something with WiFi so you can remote monitor which this doesn't have.The features to price ratio for this makes it hard to recommend for most people unfortunately despite the impressive tech. At this price, remote monitoring is absolutely needed to make it worth it. There are offline models for less than half this price, you would essentially be paying $100+ extra for just the graphing features on the app which is not worth it imo.

I don't have a way to confirm the accuracy of the CO2, PM2.5 or VOC readings. However, they do seem reasonable, and I have confirmed that temperature and humidity are fairly accurate.When I first turned it on, I was surprised at how high the CO2 level was! Our house had been closed up due to it being hot outside. I opened the windows and the CO2 level dropped quite rapidly. I hadn't realized how high it gets, now I know and have a way to keep an eye on it.We sometimes have really nasty forest fires and the air can get pretty gross during the spring and summer. Fortunately, there are not many fires this year, but that does mean I can't really see how well the PM2.5 sensor works.The VOC levels are overall low in my house, but when I moved it to my office I found that the levels climbed into the caution zone. I opened the window (cool rainy day this time) and the levels started dropping. Handy to be able to see these things that you wouldn't otherwise be aware of.So, this may be one of those tools that I didn't know I needed - having seen both VOC and CO2 levels that are higher than I would like but didn't otherwise notice, it is good that I have a meter now that can detect those things.On a year when we do have a lot of active fires, this will be handy to monitor the indoor air and let me know when to turn on the air filters to lower the particulate PM2.5 levels.The device seems to be pretty low current draw. I charge it up a few days ago, and it has been merrily running and constantly displaying data (Bluetooth off) and is still showing full battery. I did briefly turn on the Bluetooth and download the app on a device I rarely use (for security purposes - I tend to distrust many apps out there) - the app works fine and mirrors what the screen displays, I mainly downloaded the app so I could get the clock set (no other way that I can find to set the clock). Now that it is done I probably will go back to just using the screen display. I often prefer to use Smart devices in their less-smart mode when possible just because I think the alternative is unwise from a security standpoint - way too many people out there trying to steal my identity and otherwise hack my devices, no reason to make life easier for them.So, from what I can see so far, this is going to be a very useful tool for ensuring my indoor air quality is good. It would be nice if it monitored radon levels as well, but otherwise it keeps tabs on a number of important indoor air quality parameters.

The Temtop Indoor Air Quality Monitor tracks PM2.5, VOCs, CO2, temperature, and humidity. The app connectivity is very convenient, providing real-time updates and historical data.Pros:Comprehensive monitoringEasy-to-use appEasy to setupTemperature, Humidity, CO2 detection, VOC, and Air Quality MonitoringCons:ExpensiveOnly Bluetooth is supported, WIFI is not supportedFrequent charging neededOccasional sensor variancesOverall, a valuable tool for maintaining indoor air quality.

The clear display and coloring bar make it easy to understand the air quality in my home at a glance. It's reassuring to have such detailed information to help maintain a healthier living environment.The real-time updates are incredibly useful. I can monitor my home's air quality from anywhere, which is particularly handy when I'm not at homeSetting up the monitor was easy. I simply downloaded the app, followed the straightforward instructions, and it was ready to go. The notifications on my smartphone alert me so I know when I should be closing my windows!
