Dear all,
I just started with Esphome and want to integrate a 4x4 matrix keypad.
So far the ESP8266 (nodemcu V3) is connected to Esphome, but I dont see any keys pressed in the log. Dont know if it is a configuration problem or a hardware problem.
my yaml is as follow
esphome:
name: esphome-keypad
friendly_name: esphome-keypad
esp8266:

This is the keypad
I connected from the left to the right
D1 to D8
like the pad on the right
not sure if it is 100% correct, but at least is should see some output even it is the wrong key.
Any ideas ?
