Disarming the system after Entering correct PIN

[Shimaa]

Hello Everyone Please I'm trying to create a security system with scripting (Arming / Disarming after entering a specific PIN code), but I'm still a beginner, I used your script with the same steps mentioned here:

 https://openrb.com/example-allow-switch-...alization/
but I faced an issue when pressing the Enter button which has the following script : 


local value = dpt.decode(event.datahex, dt.bool)
if value then
  -- get current pin
  local pin = storage.get('pin', '')

  -- verify pin number
  if pin == '1234' then
    grp.write('1/1/7', 1)
  end

  -- reset pin
    storage.set('pin', '')
    grp.write(event.dst, false, dt.bool)
end


I noticed that only it get the current pin then rest PIN only without verifying the PIN code. 
so what should I do? 
Thanks for your time.
