I like how this quietly documents a process that’s been lost under “content creation.” No talking heads, no affiliate links, just the build, the notes, and iteration until it works. It’s what blogs used to be before they all turned into SEO farms.
The title undersells it, it retreated. We open sourced the visible parts and then built a surveillance and firmware monoculture underneath. Every “smart” thing is a dumb terminal for code we can’t audit. The GPL didn’t fail, we just stopped applying it where it mattered most.
Every time someone does a project like this, it exposes how trivial “IoT” really is once you strip away vendor lock in and buzzwords. A $3 sensor, a 10 line script, and a 40 year old ham protocol outperform half the commercial weather APIs out there.
