[edit]
If it is not getting data, switch RX/TX as a first option.

Modify the pub/sub as above
restart emonhub
sudo systemctl restart emonhub.service and post the initial log.
Oh and fix SSH 
lol, I shall fix the ssh.
When you say post the initial log, I assume you are referring to the emonhub.log? I can get that from the gui?

Got it working!!!
Had to change the loop in the sketch, wants only numerical values, so no key value pairs:
/*

#include "EmonLib.h"
// Create instances for each CT channel
EnergyMonitor ct1,ct2,ct3, ct4;
unsigned long lastpost = 0;
const int nodeID = 6;
// On-board emonTx LED
const int LEDpin = 9;
void setup()
{
// Setup indicator LED
pinMode(LEDpin, OUTPUT);
digitalWrite(LEDpin, HIGH);
Serial.begin(9600);
// while (!Serial) {}
// wait for serial port to connect. Needed for Leonardo only
Serial.println("emonTX Shield CT123 Voltage Serial Only example");
Serial.println("OpenEnergyMonitor.org");
Serial.print("Node: ");
Serial.print(nodeID);
// Calibration factor = CT ratio / burden resistance = (100A / 0.05A) / 33 Ohms = 60.606
ct1.current(1, 60.606);

ct3.current(3, 60.606);

Got the info from this link:
Thatâs because you have the wrong interfacer for that format. You are now using the Serial interfacer that requires space-separated values; the EmonHubTx3e Interfacer requires key:value pairs.
The latter carries the name of the variable with it, the former means the data arrives and you need to interpret what it is.
Ah, my bad, I said to remove the wrong one 
Thanks for all the help guys.
Really appreciate it, got it all up and running.
Hopefully, this thread will help someone else at some point.

Sorry, lol. Installed it all, was running nicely, but then after a power cut, my inputs have gone to minuses. Any idea at all why that would suddenly happen?
I thought it could only do that by putting the CTâs on the wrong way around. But I definitely had positive numbers when I switched it on to test it, and havenât taken the CTâs off since then.
My initial thought is the calibration somewhere has got corrupted. I would start at the emonTx Shield and check that the outputs from that are sensible. If that looks OK, check the numbers in emonHub.conf
