Built for me,
Useful to everyone.

Most of this started as something I needed at home — a sensor that didn’t exist, an API nobody had bothered to wrap, a number I wanted on a dashboard. Then I cleaned it up, documented it and released it as open source.

It’s the same work I do on the websites, pointed at a different problem: read the protocol, handle the failures, ship something that keeps running when nobody’s watching it. No API keys to beg for, no telemetry, no maintenance debt dumped on the user. If you want to know how I build them, the code is public.
