Heimdall alarm keypad

Hi,

I configured Heimdall and it works pretty good. Recentelly I mounted a Ipad air on the wall to control also the system.
Does somebody know how to add a “virtual keypad” to desactivate the alarm?
Thx

Anyone? I would also like to control my Heimdall alarmsystem via a digital keypad on a ipad on the wall next to the entrance door.
