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.
Mkay, I don’t know how crazy this is going to sound but here you go:
Back 3 years ago, I was still crypto mining with a bunch of good old RX470s that had been running since 2017. I had like 8 rigs in the basement. I also had solar power on the roof, but not enough to make the mining “free” since I didn’t have batteries either so I had to do something to get the power bill down.
So…since my inverter was connected to the network with a simple web page where I could get information like the actual output, I set forth to code an automation to turn my rigs on or off depending on the output of my solar panels. I used a php script running in a cronjob on a linux machine, nsclient on the windows miners and some zwave plugs to automate the on/off procedure.
Worked great for like 2 years until I decommissioned it all.
