How about a combination of Presence and Unlock actions? Presence triggers a routine which changes the mode and disarms the Intruder App. If presence fails, when you unlock using your code (either on a lock or on a keypad), configure the LUM app to change the mode or run the same routine when it’s unlocked using a code. Infact you can use the keypad itself like a standalone way to disarm the system if needed or connect it to a garage door and it can double as a garage door “lock” keypad which also disarms the system or arms the system.
