Yes! Finally got my Air Quality kit.
I know what I'm doing tonight 😎
It is fascination to see what is going on with my room air CO2, especially with per-second resolution.

Had some issues with wildly inaccurate and fluctuating Co2 measurements from my Senseair S8 sensor.
So I put it next to an open window, added a Start Calibration button in ESPhome, and I am now trying to get it manually calibrated enough to be usefull again.

Received my #airgradient air quality monitor and set up #esphome. Took me a while to realize that the USB-C connector at the back of the monitor is only for power and that I need to plug straight into the board. A whole world just opened up to me with esphome and custom ROMs.
It works! I guess I can still solder.

Sometimes you do have to recalibrate #Aranet4HOME. This one is about 3 months old, and after several hours outside, it hovered above 500 ppm. Should be ~420 to 440. Recalibrated and all is well. My #CO2Click and the Aranet4 are getting along quite well now.
Can't wait to compare both to the DIY #AirGradient arriving soon...
