Achim from AirGradient here. I fully understand your frustration. Maybe a bit of background information to put this into perspective. Until around a year ago, the open-source DIY kits where a seperate 'side project' as we focused on our (now retired) closed source air quality monitors. However last year we decided to go fully open-source hardware and started to merge the closed source features into the open-source firmware. Because we needed a much better code base, a complete re-write was required (also supporting two different MCUs). So the last 6 months was really a transition period and things were a bit messy but I believe we have a much better onboarding and instructions [1] now available on the website and are continuing to work on it.
