Hey, did you make sure to connect the module to the AC? It is actually not powered by the 5V you give it from the Arduino. It uses the AC to power itself. The 5V only power the opto-couplers which isolate your Arduino form the mains....

Thx for your email.Yes Ac 230V is connected but not CT.It seams for me that there is no signal pn RX port. No Led flashing like on TX.Am 21.04.2020 14:15 schrieb Jakub Mandula <[email protected]>:

Hmm. that is strange. The CT not connected should not be causing any issues (you will just read 0 current).
Could you try this, swap the RX and TX wires. Maybe you have them the other way around
