Ordinarily this would mean you need to buy prefabricated 3.5mm TRS cables and cut one end off to wire them up to the CT, because it's difficult or annoying to terminate your own 3.5mm TRS plug connector.
Why not some other connector choice? Maybe RJ11, or one of the typical 'green' two conductor terminal blocks socket/plug combos with latches you can get from Digikey or Mouser?
I wonder about the choice of 3.5mm TRS stereo jack for the inputs.

Earlier quoted context omitted.
Out of curiosity, do you plan to add a sensor to every output breaker in your box? I'm interested in a closed (for everyone but ME) system as well. I'm not sure I'll be able to fit much hardware in the breaker box so I'm unsure.
If this is possible, I know my breaker box has enough room, but is there any risk with all those cables with the 3.5mm end causing arcing? How do you route them out of the box? Should the wires criss-cross? Bundle them?
The future of IoT is open, hackable, and decentralized. The IoTaWatt looks like a big step in the right direction.

All these current sense coils come with 3.5mm so I think thats why they use them.

This style also has an integrated burden resistor, which makes it far safer than a plain current transformer.
For example, if you're a ComEd customer in the Chicago area, your smart meter is Zigbee-enabled and works with a handful of approved devices:

The information won't be as finely detailed since it's not sensing every circuit in the home, but for $70 and no tinkering necessary I can read my home's consumption in XML format every 10 seconds.
Just an FYI that your home may already have a grid-connected meter outside, and it may already have a wireless interface.

What do you do with this information? I can see it being useful for detecting anomalies, but for every day usage... I am not going to stop using my refrigerator to save power.
