I don’t want to hear about your Plex, your NPM, your notes application or science forbid, your budgeting application. I want to hear the most exotic thing you setup to selfhost, that probably only you and a hand full of people around the world actually use or even need. A problem that you solved in a way, that makes people go WTF. Go!
I’ll start: I live in the mountains, and there is snow, lots of snow. I often tell people “We had 3m of snow last year”, but is that really true? So, I thought to myself: Can you measure snowfall? It seems you can, so I setup a USH-9 ultra sound measuring device, connected it via IC2 to my Home Assistant and now I can tell people with confidence, that we had a total of 3.45m of snowfall last season, with max snow height of 60cm on January 5th.
Future project: I have chickens. They lay eggs. I have cameras. I want to know which hen lays how many eggs. Solution? AI image recognition of the hens (who is who) and if they have laid an egg. Any inputs welcome.
Love the stuff from the comments here.
For me, not so WTF but still a little overkill. My Parents have a sauna in the Garden which we occasionally use. But in the winter it’s cold and you don’t want to check outside for the temperature of the sauna until you go in. So my cousin and be build a little WebUI and Python script which allows us to monitor the temperature and control the state of the sauna remotely. 10m from living room garden sauna saved 😅
