Qingping Air Monitor

Dont those already work via Bluetooth? My Air Monitor Lite at least do.

I have an Eve Room and I quite like it. The little e-ink display is incredibly easy to read in most lighting conditions (i.e. any condition where there's some light), and the battery life is really fantastic. I also have an air monitor from Qingping[0] which I got from Amazon, and I quite like that as well. Instead of VOCs, it reports pm2.5 and pm10 particulate, which was important for us (in Vancouver) because of the advent of 'wildfire season' in the past few years. I think I would prefer to have the pm2.5/pm10 sensors in the living room and bedrooms (which have windows and where people spent the most time) and the VOC sensors in the kitchen (where cooking/burning happens) and bathroom (where cleaning products are used but ventilation is poor) but I haven't gotten around to buying more of everything yet.

For PM2.5, the Qingping Air Monitor (or the Lite version if you prefer that) is good. The review I've read found it has decent accuracy, and, though I haven't tested it rigorously myself, the readings seem reasonable in my experience. The main reason I recommend it, though, is that the UI is great: it keeps graphs of past values that are easy to access, both on the screen and in the app. On the topic of allergens, I wasn't able to find any device that can measure that.

I've had similarly bad results with CO2, PM2.5, and PM10 concentrations when I use my gas stove. If anyone is curious I have a Qingping Air Monitor Lite which I love. It's probably sucking up my data but I don't mind too much because it has a great physical interface, natively connects to HomeKit so I can see the current status and trigger events when levels get too high, and has a decent app that shows charts over time. It's nice to be able to remotely see that particulate levels are rising and turn on my air filter for a bit so everything's back to normal by the time I get home.

I chose the Qingping Air Monitor Lite ($100) specifically because it can connect to HomeKit, but it doesn’t require it and you can use it totally fine without ever connecting it to the network! Though you might need to connect it once if you want to modify default settings like changing it to Fahrenheit. I actually find the device to have a really responsive offline interface that you can use by swiping the top of it. To give you an idea of why I wanted a “smart” one because I know on HN it’s a polarizing topic: I can include it in my HomeKit dashboard and see it from the other room or when I’m not home, get alerts when it reaches a certain level, record data automatically, and trigger automations like turning on my air filter.

I have a qingping air monitor lite, which was around $70. It also measures PM10 and PM2,5 which helped me show that my wood furnace is indeed leaking something sometimes when I noticed it smelling weird.

Qingping Air Monitor Lite is decent and costs even less than the Awair. It doesn't measure VOCs though.
