Using 12v on Digital Input - DW1 - 01-05-2025
I am using a KC898-A16 in ESPHome. I have it successfuly set it up in ESPHome/HomeAssistant. I can switch the outputs on and off and if I connect any digital input to ground (dry contact) I see it as input in ESPHome.
My issue is that if I apply 12vdc negative to the digital ground and 12vdc positive to any digital input I get no input.
I have tried setting invert = false
It is my understanding that it is possible to apply 12vdc to a digital input and get a result.

input 12v dc = logical "0" means: NOT trigger.
input 0v dc = logical "1" means: trigger
so if you want input voltage, 0V and 12V for different level.

I tried all inputs - no reaction

because you need download KCS v2 firmware. new board no firmware inside of ESP32.
set IFTTT let digital input TOGGLE output.

when download firmware, make sure removed RF433M RF receiver.
