Airthings just launched a new product.
You can use batteries and main power.
The View reports every 5 minutes and it looks nice.
It would be a great device for monitoring air quality and set temp for systems like z-water.
With metrics for Air quality we can make ventilation or air cleaning systems smarter.
Please wote this up if you need it:
