The point of this was to avoid damaging existing wiring on the flow sensor, and also to avoid requiring fine motor skills to assemble a tiny keystone. I wanted make the temperature sensor more of a plug-and-play like addon, just like the flow sensor.
Disclaimer: I bought the splitter a month ago from China, and I haven’t received it yet. When I do get it, I will post pictures and confirm whether or not it works.
I bought an RJ45 splitter from Amazon and cut an existing ethernet cable in two. It seemed much easier than punching down a keystone, since all I’m doing is twisting wires together.
flow sensor — ethernet cable---- rj45 splitter — ethernet cable— kegboard
temp sensor — ethernet cable --/
The RJ45 splitter needs to be the 8 wire to 2x8 wire, and not the 8 wire to 2x4 wire kind. They usually say that their product doesn’t allow two computers to be connected at the same time, but we’re not connecting computers in this case.
I attached the temp sensor to the ethernet cable same as everyone else:
Orange (Pin 2) to Sensor Red
Blue/White (Pin 5) to Sensor Black
Orange/White (Pin 1) to Sensor White
The major upside of this install is that if a temp sensor fails, you can just unplug its ethernet cable from the splitter, and not have to open up anything to rewire. Unfortunately if I want to add an iButton/NFC in the same plug-and-play manner, I would probably have to chain another splitter, since I can’t find a 1-3 splitter
