Helper script (2nd link) is easier to use. simple AF (first link) is fully open source, but requires you to use another bed leveling probe - no open source „driver” for prtouch- the built in one (which is slow and not terribly accurate anyway).

Every Pokémon game has their current console in your room.

I don’t think so. I haven’t built mine yet. JSN comes with a pretty long cable, so you could but just the probe in your well and keep ESP above ground to have Wi-Fi. You could battery power the ESP32 and use deep sleep to conserve battery (you don’t need to have probe reading every second or minute, right?). You could even try to use solar power to charge the battery. Possibilities are endless.

I’m going to try to mount a probe in a sewage tank - I have a few cables left leading to it. That means I don’t have to worry about power or Wi-Fi - Esp32 i going to be at home, the probe and its control board inter sewage tank.
