As well as being a useful user interface, a keypad can also be a good indicator of both occupancy and occupancy and presence to the contextual smart home. Pressing a key provides occupancy but entering a valid PIN enables occupancy and presence to be determined.
Keypads don't have to be physical pieces of hardware as this Amazon Echo Show 8 demo shows. It uses a software keypad to authenticate users, deliver a personalised user experience and provide additional occupancy and presence context to our Home Control System.
