What can the 'average Joe' start hosting, that will change their life? - eviltoast

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!

    I have a PiHole, my own EdgeRouter that is behind the Verizon router, a UPS, a wired switch, a SiliconDust HD HomeRun to convert my cable to a stream, my Hue controller, my Camera DVR, and a Pi4 hosting network storage.

    It all fits neatly in a 6U closet rack. I use the EdgeRouter to host a VPN I can connect into to manage things for the house, and also use it to dial out to a VPN, so I can connect the TVs in the house to a VPN abroad.

    I also have a Smart Garden powered by a raspberry pi, connected to a rain barrel, a water pump, some solenoids, and some moisture sensors.

      Smart garden sounds amazing! My girlfriend would love that… Maybe I’ll set that up with her!

        Yes I actually have two of them. My backyard has three outdoor moisture sensors, so it can know if it’s moist enough. It has a drop irrigation system connected to regular plastic pressure for tubing. It has two zones that can be controlled with two solenoids. It also has a 12V pump. All of that is powered by a 12V power supply and controlled by a four zone relay board. Remember to turn the power off to your outdoor sensors so that they don’t destroy themselves when you’re not sensing. You can also add a flow sensor to measure your water consumption.

            If you can do python and you can wire one part to one part, one part at a time, it’s not hard, at least to me. Get the analog sensor, connect it to the analog to digital converter, connect all of their power to a relay, connect the relay and the converter to the pi, connect that to power. Then use Python to check the value in a loop, forever.

          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.

            ACEIRMC 2set Soil Moisture… https://www.amazon.com/dp/B09JSND12L?ref=ppx_pop_mob_ap_share

            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.

            To read the analog values, I use this: HiLetgo 3pcs ADS1115 16 Bit 16… https://www.amazon.com/dp/B07VPFLSMX?ref=ppx_pop_mob_ap_share

            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.

          I was considering a smart garden setup as well. I ended up going with a dumb version that has no dependency on any electrical power: Blumat. They’re from Austria, if i recall correctly. They feed water as the plants consume it.

          The Blumat “carrots” are porous and as the soil dries, pressure becomes negative and opens up the switch that controls the feed water line, which then drips water onto the soil until its reached the calibrated moisture level which closes the switch.

          Not “self-hosted” in the traditional sense but definitely hosted in the primitive sense.

            Those sound really useful. I like the no power aspect that just works.

            My larger system is entirely 12V power and is connected directly into a 2-panel 24V solar system with battery.

            But entirely mechanical without external input like power is a really good idea.
