Our water boiler doesn't have a way of monitoring the temperature in the hot water tank, so I'm gonna solve that myself with a temperature prob and a small Linux box.
I'd like to take a temperature reading every so often (haven't decided on what frequency yet) and have the results displayed in a graph viewable over http from the comp.
Any suggestions for showing that in the simplest way possible?
@fatedfox I had seen this when searching but I've found docker to be pretty confusing/my brain can't parse it well, so had discounted it. I'll keep it in mind though, thank you! :)
@fatedfox @renbymon skimming the page quickly I'm not sure there's a need for docker other than they didn't want to tell you how to set up Prometheus and Grafana from scratch. If youe more comfortable installing them both directly on the Pi from the respective project documentation it can't anticipate anything docker is bringing to the table here

@renbymon Maybe munin?
@darac I think that's exactly what I'm looking for, thank you! :D
@renbymon Nice work! It's probably not far off the temperature of the water, to be fair. After all, the tank is metal.
Jeez this took an age to get working but it's done!
A DS18B20 1-wire temperature probe connected to a RPi 3A+, monitoring the temperature of the water in the hot water tank (as best it can; it's just touching the outside of the tank).
Data collection and display is being done by Munin (thanks @darac for the suggestion!) node on the Pi, master on my home server.
