Slight update on my build. Still waiting on USPS to deliver the last item so I can hook up the ph probes... built a custom wire harness to clean things up and a power and ground distribution hub (picture was before I fixed a couple solders). Also for the ds18b20 probes, the wires were 28 guage. Most common wire strippers don't go that low.

Additionally, I am looking for usb powerbank with a pass through to act as a UPS. Any recommendations? If not, the wire harness was designed to free up the pins for a pre-built pi UPS.
