Existing Alarm Keypad ESPHome

Hi All,

I have an existing wired alarm system that i have removed the original controller from,
I have all the PIR sensors and the tamper switch working with an esp8266 and ESP Home.

The last and missing piece is getting the existing wired keypad working… Does anyone have any ideas?

Cheers.

For Reference this is the inside of the panel

Going to try to revive this, does anyone have any ideas on how i may get this to work?

Thank You
