Yes these. Essentially anything that an unidentified user could push data to that would land me in regulatory trouble. I would want to host these things, but I don’t want to become a distributor of anything that would get me a search warrant.

This was not a helpful response. I also don’t know what it is.

This is an old Stack Overflow approach. Don’t say that you can’t figure out how to do something in Linux, say that Linux can’t do it. You’ll get examples.

I don’t understand it, can you share more about what it is?

Relatedly, some long structures that seek entirely straight have different lengths depending on the altitude you measure them. For example, an oft repeated tidbit is that the Lake Ponchartrain causeway is two inches longer when measured at the deck than at water level due to the earths curvature.

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.

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.

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.

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.

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.

My view for a short forever. I still have it available in the hopes that they either reverse course or refeature it to target a different platform

That won’t happen though. Still trying to get into Tildes where he went, hoping for the same app experience.

I like wefwef. It feels familiar, but there’s nuances. It’s a bit of struggle to transition to this new interface. Reply and upvote and downvote are behind a menu, not right at the bottom. Clicking the message collapses it instead of opening options. But it’s fine, I like it so far.
