What panel to buy?

I currently have a house with motion sensor, door sensors and window sensors and a “dumb” keypad.

What I’d like to do is the following :

  • Keep my current wiring/keypad for people that don’t have a smartphone etc
  • add my sensors and alarm to HomeKit (I have a rpi running homebridge)

This is the alarm kit that is currently installed, what model should I buy if I want to use both my OG alarm system and the Konnected kit?
