The Challenge

01 Four arming modes
Stay, Away, Sleep and Disarm must all be reachable and unmistakable from the home state.
02 Lights, scenes, access
Lights and scenes controlled straight from the keypad, plus adding and removing users and PINs.
03 Zones and simplicity
Zone bypass and sensor status, in an interface that stays simple and friendly for every kind of user.

Old Keypad

Legacy keypad interface Crowded layouts, unclear button hierarchy and inconsistent feedback — hard to read in stressful or low-visibility conditions.

Color Palette

Navy and coral palette Contrast testing
Deep navy for stability, coral for focus. Accessibility testing exposed contrast limits at small sizes — the input for later refinement.

Time, arming state, alerts and connectivity stay legible at a glance — without touching the keypad.

Takeaway & Reflection

Redesigning a keypad is less about screens and more about trust.
