I've seen a few different people post about different air quality monitors they're using and integrating into HE:
@Digital_BG - Awair - [Release] AwAir Elements Driver - co2 air quality monitor
@pedro.f.andrade - Awair - Awair Air Quality
@Inpier - Foobot - Foobot Air Quality Monitor
@storageanarchy - PurpleAir - [RELEASE] Free Device Driver for the PurpleAir Air Quality Station - Now with Hubitat support!
@LostJen - AirThings - [RELEASE] Air Things Wave Plus support + HM3301 laser PM2.5 (using Grove I2C)
I'm just curious as to what people think are the best for monitoring indoor air quality and integrating with HE for automations (e.g., turn on the HVAC fan, send an alert). I have plenty of sensors that monitor for temp and humidity, so I'm not so concerned about that. And I live in a high-rise condo, so radon isn't really of any concern for me either. However, carbon dioxide, VOCs, and dusts (PM2. 5) are definitely of concern. Especially with us all spending most of our time at home with COVID-19, I'd just love to be able to monitor the air quality a bit more and be able to setup some automations in Rule Machine to help control the air quality inside a bit more.
Awair seems like it monitors/reports most of what I'd be interested in, but I've read some reviews that are giving me some pause regarding the company and them backing their product/customer service issues. I like the look of Airthings, but am surprised they don't have a PM2.5 sensor... I see @LostJen was able to use a separate sensor to monitor for that though, so that's an option. Any feedback would be much appreciated!
