KC868 Outputs not working

[blazej.k]

It seems that my outputs are not working (no leds, no voltage change).

I measured the voltage on the optocuplers and its ~1.1 V beetween optoupler legs (as on image):

   

I tride official firmware and esphome, both are responding to commands (on = 1.1V, off = 0.0V)

take a photo how you wire your KC868-A16 board, i think you have not connect green terminal of Vin with DC12V.

Wiring was kind of ok. The wire supplying power to output part was faulty, it seem to have almost no resistance when out of circuit, but broken in the middle. That is first time when new electrical wire (stranded) was broken.

Thanks for the tip.
