Additional GPIO

[Amaral989]

1. on the right bottom GREEN terminal, there is GPIO1 and GPIO2 port connect with ESP32 pins directly, so this can use for read pulse.
2. if you download KCS firmware, there is INPUT webpage, can invert the logical of INPUT, so that use 12v for TRUE.


Thank you for your response... 
Those GPIO are the ones i am using currently. I damaged GPIO 1 , is there another i can use except for GPIO2 , to use as a pulse. 

I'm a little confused on second answer. Im currently using ESPHOME. Am i still able to use KCS firmware as well as ESPHOME , to invert the logical INPUT. 

Thank you again.
