What Hacker News says

6 sources
With our latest firmware we now natively support Home Assistant and the monitors are auto discovered. So no need to flash ESPHome anymore. We also expose a local API that makes it very easy to make GET requests to the monitor within your local network and basically gives you all possibilities for easy integration.

In Air Quality Monitors Compared: AirGradient One vs. Airthings
Hi Achim, thanks for the response! Would it be possible for you to document somewhere how to flash from source? The website currently kind of explains it under "Flashing Of The AirGradient Firmware," but step two is to flash the "ONE_V9.ino" file, but there's no explanation of where to get that file. I know it used to exist on AirGradient's Github[0], but now I don't see it anywhere after the v3 rewrite. [0] https://github.com/airgradienthq/arduino/blob/2.4.15/example...
In Ask HN: What indoor CO2 monitor do you recommend?
I also own an indoor AirGradient, and I like supporting open-source, open hardware, but I've been pretty disappointed with the product. There were no instructions in the box, and I had to dig around a while until I found this PDF from three years ago.[0] I normally can figure out a gadget without reading instructions, but this wasn't self-explanatory, as there are no inputs on the device itself, and I had to figure out how to connect it to my WiFi. It's open-source, but there are no official instructions for re-flashing the device. I had to piece the process together from third-party blog posts. The code itself is pretty low quality. They use tons of globals that could trivially be local variables, and they throw away precision of floats by casting them to ints. I fixed a bunch of bugs in my fork[1] and started contributing them upstream,

and the maintainer told me that they just did a giant rewrite, so I'd have to re-do all my changes.[2] I get that it happens, but I would have preferred they announce in the README that the code is deprecated and not to work on it until this rewrite is complete. I still think it's fine overall and I'd probably buy it again for other rooms in my house, but I hope they get their act together a bit more.
