@jp.vanriel yeah, I had actually originally installed CAT6 cable, and did the double pair thing, but thought it wasn't working so ended up buying the flex wire and twisted the 2 to make the twisted cable. It turned out I wasn't getting the CT reading as I hadn't switched on the grid feed. I then tested the CAT6, single pair, and got readings just fine, but reconnected the flex wire twisted cable I'd made anyway and reused the CAT6 for my RS485 link to my Home Assistant box...
