M16v2 and SCT013-050 - SixSixOne - 06-10-2026
Dear Sir,
I have bought a M16v2 recently and try to make it work with SCT013-050 50A/1V sensors (https://www.aliexpress.com/item/1005009291075507.html?spm=a2g0o.order_list.order_list_main.162.2e061802lqJyc9) with the jumper positioned in the "V" measurement on the board.
I've used the last yaml code you provided (also attached) however it is not measuring anything.
My house has 3 phases and I have already checked all 3 phases as they are coming from teh grid as well as from a socket.
I've never received any measurement the Amperage is always 0A and the RAW measurements 0.11A, 0.12A, 0.13A
Any idea what is going on?
Tks a lot

please confirm with the CT seller, whether is 2000:1

Hello again,
It is 1800:1
RE: M16v2 and SCT013-050 - admin - 06-11-2026
you should chose 2000:1 CT sensor, suggest you buy CT sensor from KinCony online shop.

Ok this I can understand however since I have already 16 of them and the problem is that I'm not receiving at all measurements I need to figure out whether there is somewhere else the problem.
Wven with 1800:1 turn ratio the sensor should measure bigger Amperage then the 2000:1 and with the same burden resistance to give more than 1V measurement to the controller (when it measures 50Amp , the maximum possible measurement). In my case Im not receiving measurements at all... like the sensors are not operating or the controller is not logging the measurements.
Tks a lot.

take a photo , how you wire your board.
