AmazonSmart Air Quality Monitor – Know your air, Works with Alexa

Ordered the device and had it the next day.I ordered this device to get a handle on our indoor air quality. The motivator of this purchase is the current wildfire pollution effecting many areas of the country and knowing the impact of the winter heating season on air quality. The measured parameters are perfect for this assessment. Carbon monoxide (CO) in particular is a dangerous. As stated by the product description, this device is no substitute for a CO monitor/alarm. What I find interesting is the error some make in not understanding the difference between CO2 carbon dioxide and CO carbon monoxide. CO2 is not a life threatening gas, but CO is! CO2 is produced by the human body as a end product of body metabolism whereas CO is an end product of combustion. Bottom line, elevated CO can kill you within a matter of hours based on how it arrests the carrying capacity of oxygen in the blood. Every home should have a CO alarm! The other misunderstanding is about radon. You measure for it once in your home, if it is high, you install a system to eliminate it. Done.This little device is just what you need to make sure the air you breathe is safe, no more, no less. Newer homes that are built tight for heating and cooling efficiency need a ventilation system to introduce fresh air and eliminate stale air utilizing filtration. An older home such as ours (built 1956) tends to allow air infiltration so there is an element of air exchange at the expense of efficiency. Either way, an air quality monitor such as this device can give you peace of mind.Installation took less than 10 minutes having multiple Alexa devices. Got my 1st report and a green light on the monitor within minutes. I really like the report on the Alexa app and Echo Show. I can access it from my phone as well. Nicely done Amazon. Recommended.Update: 8-2-23Had this for a few days, very impressed with the overall sensitivity of the monitoring. Examples; 1) was sanding a piece of furniture in the basement one level below the monitor. Within minutes the monitor displayed a yellow light and the monitor readings indicated a moderate elevation in the pm, particulates. This resolved back to a green light, good air quality level, within an hour after I stopped sanding. 2) had our home cleaning service in to do a complete deep cleaning, within minutes of their use of cleaning products (strong smell), the monitor went from yellow to red indicated a high level VOC’s in the air. This too reversed within several hours after the home cleaning was completed. If anything this demonstrates that knowing about changes in air quality in the home can be valuable to help with selection of safer home products and better control of hobbies or habits that create environmental dusts. For me and my health this is a valuable tool to manage home air quality.Update: 8/8/23Spouse used denatured alcohol in the basement to clean wood table surface. Within minutes of using the chemical, the monitor responded with elevated VOC’s. I noticed the red light on the monitor an hour after use and checked the parameters from the Alexa app. The air quality was poor! VOC’s were in the 90’s. Opened windows on the 1st floor and basement. Within 20 minutes the poor air quality began to reverse. VOC’s were now in the 30’s with moderate air quality and a yellow light. Next time no use of denatured alcohol in the house.Final update/comment08/20/2023Overall, very pleased with this device. I’ve read other comments and find some that (I believe) have unrealistic expectations. This is a simple air quality monitor not a laboratory grade instrument. There are established ranges of accuracy but for what you pay this thing is great. As far as it’s integration with Alexa, I find it easy to use, gives me a quick account of air quality, and provides historical information. Graphics are good when using my phone or iPad. If you have concerns about indoor air quality and you use Alexa devices, I don’t see how you can go wrong. Highly recommended.

Monitoring:This device monitors IAQ, temperature, humidity, particulate matter, carbon monoxide, and VOCs. I’ve compared the readings to other devices, and they are all pretty accurate. This device can control Air Purifiers, Humidifiers, Dehumidifiers, and Thermostats. It refreshes frequently and gives you lots of graphs with the data. Also, it saves your data for comparison over long periods of time.Routines/Automation:You are able to write Routines for both Events and Actions. I included some pictures of what the these screens look like. You are only able to write those routines/automations in Alexa, although I’m not sure if they will work with Home Assistant or not.Pros/Cons:The device actually has a little, quiet fan on the inside that sucks in the air to run over its bank of sensors. This provides quick, accurate, ambient readings. However, none of the sensors are replaceable. So, when the sensors get compromised by dust, etc, you will just have to throw this device away and get a new Air Quality Monitor. Most Air Quality Monitors at least make the particulate matter sensor replaceable.This Air Quality Monitor is one of few that actually comes with a tripod mount. I really like to see this because you can position the bank of sensors in the air and off the ground. Unfortunately, unlike 99% of all Air Quality Monitors, this one has no display. Even the cheapest ones will have a little display showing the temperature and humidity. It will also only work with Alexa, although I’m not sure if it works with Home Assistant or not.

I’ve only had this product for two days, and it was showing all good readings on my air quality. I noticed after cooking dinner on my gas stove, the LED light had changed. I checked the app to see my air quality tanked! Now I know I need to open a window or have the vent on when I’m cooking. Really cool, and excited to improve the air quality in my home.

Great so far after 2 weeks. Bought it since our home was smoked out after the Eaton wildfires here in Southern California. Our home has been declared unlivable and even after 3 months, the he VOC's are real high and the Particular Matter is too. Good to know and might help keep out insurance adjusters on their toes instead of falling asleep on the phone as they sometimes do...

Works perfectly as a temperature based trigger for Alexa routines. Even does carbon monoxide ones as well. There's no flashy display and it uses USB micro for power but you should've known that before you bought it. It's not intrusive and you can even turn off the LED light on the device via the Alexa app.Update: This device has become unresponsive twice so far and it hasn't been able to recover by itself. Once it was plugged back in it took avery long time for it to recalibrate. I'm not impressed with two manual interventions in under a week Amazon.
