I have my Flukso V2 ready to go, and have purchased a pair of pulse-output kw/h meters which mount to the DIN rail in my electricity meter box. I have a 100 amp meter for consumption and a separate 32 amp meter for solar generation. These meters are connected in-line with the mains from the relevant breakers.
As my meter box is outside, I'm planning on using my ethernet wiring to carry the pulse feed (+5v) from the Flukso (inside the house) to a custom cable which plugs into the closest Ethernet socket, then to the server rack where that port is patched into the wires directly from the meter box.
What is the maximum distance for a pulse cable over solid core Ethernet wiring, and also would you consider it safe?
