Pond monitoring system idea

It has more connectors than I need, but it would be expandable. I want to have some flexibility to make changes to the system if I need to, without it being too much of a hassle. When I built my pond filter a few years ago, I had to revise it before it worked how I wanted it to.
 
I still haven't ordered parts, but I'm glad I waited, since the Raspberry Pi 4 was just released. I'm going to order that when it is back in stock.
 
Ugh, apparently the USB-C port on the Pi 4 has an issue where it won't work with some charging cables, because two CC Pins on the USB-C port should have each gotten their own 5.1kΩ resistors, but instead, they share a single resistor. I guess it's not too big of a deal, but I wish it would have been implemented correctly. I still haven't ordered anything yet, I'm lazy.

Yeah, that's what DH said. IMO, lazy engineering, lol.
