Amazon Smart Air Quality Monitor – Know your air, Works with Alexa

This is a nice little device. First you will never have two or more of these devices next to each other providing the same reading. I’m not sure why some reviews do this to imply this device is inaccurate when the test environment has unaccounted variables. So the device next to another device will give a different result and also why temperature and humidity always seem more accurate. I test this device against a calibrated analog hygrometer. Calibration is done but place the meter in a sealed bag with a small dish of salt and water mixture-so it’s like wet sand. The meter stays in the bag (a controlled environment) for 4-6 hours and the meter should read 75% when evaporation is equal to absorption. This meter is right within the standard deviation. There’s no way to offset the values but I haven’t found it necessary or inaccurate. Like others, I feel it’s a bummer this doesn’t have a screen but if you have an old phone you can link it up and it will give live updates. To keep the phone from overheating I use a smart plug that charges and waits in an infinite loop so the phone is not charging all the time, avoiding the battery issue-then you have an active display. Perfect use of the old phone in your drawer or any cheap device will run the Alexa app. You can turn off the led indicator in the app, no need to cover it with paper if you don’t like it. It’s sensitive enough and picked up the oven turning on. Link up a smart fan or use a smart plug to increase fan speed, turn on air clearers, etc. to any value you choose.

I've been searching for an affordable air quality monitor for awhile now - they're all cheap junk or too expensive. This Amazon one is amazing - takes the best feature of higher end monitors and takes it to an affordable price point. The app is good, and I like the air quality light feature (which allows you to turn it off and it will only turn on to red when low quality). Super well designed and thought out. It does require to be plugged in so there is no battery option, but I've been able to connect to it with no issues and don't have to worry about swapping batteries. Also can be accessed remotely, not like some monitors that are Bluetooth range only or require some crazy subscription. Sensor is accurate and fluctuates correctly based on surroundings!

It works very well and is insanely easy to set up. So far as I've been able to find, it's the only sensor that can trigger a routine based on temperature (or other environmental factors) without involving IFTTT or a Zigby device with a hub. Yes, it's more expensive than most but it just WORKS and that makes me happy.I use this to trigger the fan speeds on my window AC. Above a certain temp it kicks it into high. Below, it kicks it to low. The ECO setting on most window AC units, including mine, rely on the temperature sensor that is right up against the unit. I've found there is generally a 3-4 degree difference between that and the actual room temperature. This means that it often doesn't work properly for me. I tried a few other sensors and discovered that while they worked and showed up in Alexa, you couldn't actually DO anything with them except get Alexa to tell you the interior temperature. This device solved that problem.Now for the bad stuff. First, the light. I was happy to see that you can turn it off. I was unhappy to find that even if it's off, if the temperature, humidity, CO2 level, etc., gets too high it turns on a red light you CAN'T turn off. It's very bright and very annoying. I mean, yay for looking out for me but maybe the alarm on my phone is better suited as a warning...? The red light is just annoying.Next we have the Alexa integration. Like I said before, it sets up super easy and that's awesome. But after a bit I noticed a few things that started to annoy me. Once working, you have to constantly find the icon/button for the device. You cannot add it to favorites or anything like that. Once you're in it gives you a number that is an overall air quality score. Cool. However, the icon/button also has this score so it feels repetitive. It would be great if you could select which number you want the icon to show so you don't need to open it to find the temperature or whatever is most important to you.That brings me to another point. You HAVE to use the Alexa app. There's no widget or anything. Now, I realize that I wanted it to work with Alexa and I'm glad it's so seamless but the Alexa app is kinda clunky and a PITA if all you want is to know what the temperature in the room is. Sure, I could just ask Alexa but then I have to turn the volume up or something in order to hear it, assuming it understands what I ask for and doesn't try to play me "Temperature" by Sean Paul for the billionth time... and if you have your volume up, leads to loud music suddenly and a whole bunch of attempts to get it to shut up, etc.. So yeah, it'd be nice if I could just look at the Echo Show screen (you think they'd find a way to use it) or at my phone quickly since it doesn't have a screen on the device.For me, the worst thing is that you can't turn any of it off or tell what information it may be collecting and to whom it may be sending it. There's no information readily available about it. Now, maybe that's because it doesn't actually collect anything but it's be nice if they would just say that. As to the turning parts off, I'm a smoker so every time I smoke a cigarette, it lets me know that my Particulate Matter score is getting bad. After a while I feel like it's just mothering me. Yes, you can turn off the notifications but that turns off ALL the notifications. See the problem? There's also the issue of does it know how much I smoke? Is it keeping track? Who might get that information? Can it tell what the individual particulates or VOCs are?! (Volatile Organic Compounds-glues, pesticides, fruits, scented candles, cleaning supplies, paints, etc.)This lack of information and/or transparency is either a serious oversight or purposeful obfuscation. To be clear, I'm not that paranoid but I know people who are and it feels like something Amazon should get out in front of before someone does it first. Honestly, if Amazon knows what I'm doing, the worst I think will happen is I'll get more ads for snack cakes and other junk food.I'm going to keep using this and hope they make some changes. To be fair, this is a pretty new device so I'm sure they'll be looking at making some updates to it. And it really DOES work very well. Most importantly, you can trigger routines based on the temperature, humidity, CO2, PM and VOC information without having to become an expert in home automation.

I’ve used the Amazon Smart Air Quality Monitor for over a year now, and here’s what you really need to know.The hardware is solid — compact, well-built, USB-powered (which I appreciate), and it collects a ton of air quality data. That’s really its main selling point — and at this price, it should be.But then things get weird.There’s no dedicated app, no display on the device itself, and even no widget. The only way to check your air quality is by opening the Amazon Alexa app, navigating to the monitor tab, and then reading the data there. It’s clunky and far from user-friendly.Even worse — my Ecobee thermostat can’t integrate with it (and I’m not sure any thermostat can). That’s a huge missed opportunity. Imagine if the thermostat could use real-time air data to activate the fan, ventilation, or cooling in a specific zone — it would make this monitor genuinely smart.The frustrating part? Amazon clearly has the resources to build this out — the hardware is already there. But it feels like the product was launched… and then abandoned.If you want raw data and don’t mind digging for it, this might still be worth it. But if you’re hoping for smart home synergy out of the box — temper your expectations.
