I’m already hosting pihole, but i know there’s so much great stuff out there! I want to find some useful things that I can get my hands on. Thanks!
Edit: Thanks all! I’ve got a lil homelab setup going now with Pihole, Jellyfin, Paperless ngx, Yacht and YT-DL. Going to be looking into it more tomorrow, this is so much fun!
Hey that sounds amazing, may I ask what moisture sensors you are using?
Edit: also automating sensor power draw sounds like something fun to work on. I’d love to test if having them power on just before or shortly before taking a reading and power off is feasible. Or if they need more time to get an accurate reading, finding the most optimal power cycle schedule to prolong sensor life while being able to take measurements at sensible times.
They’re just resistive electrodes with an analog sense of the conductivity of the soil, which is linearly correlated with moisture. It does this by applying a voltage to one side and sensing the current load to the other probe. This is exactly the same as electroplating, so if you keep them on 100% of the time, one will essentially dissolve in the dirt.
Instead, I run their power through a relay. I turn one relay on, it turns on all three of my sensors, I wait a few seconds, take three reads off each, one second apart, take the avg of each sensor, and record that. You can the save that to a timeseries database and host that locally too. Then plot that with Graphana.
Now that you have logs, you can check moisture levels before activating your irrigation.
The next step is I have a set of float sensors in the rain barrel, towards the bottom. If the bottom one indicates empty it activates a solenoid to refill from the tap until the top one indicates full. They’re about two inches apart.
