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 connect GND directly to I1.
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.
here is KCS v2 online guide: https://www.kincony.com/esp32-kcsv2-firmware.html
