The Challenge

Four stages instead of one long setup.

Setup, Device Pairing, Programming, Testing — a structured flow that reduces errors and keeps installers moving.

01 Mobile, not desktop

Installers configure complex systems from a phone under time pressure — no side-by-side diagnostics, device lists and settings.

02 Two kinds of user

Experienced technicians want speed and minimal interruption; newer users need guidance and clarity during setup.

03 Contextual help only

Assistance appears where it adds value — after device scanning, during troubleshooting, when configuring unfamiliar hardware.

Physical Paradox device system. Brainstorm board

Brainstormed features, user flows, installation workflows and usability improvements for M Installer.

01 Understand the flow

Mapping the current installation process — unclear steps, outdated components, points where configuration confuses users.

02 Improve guidance

Clearer navigation, step-by-step progress indicators, simplified configuration options and contextual help.

03 Make it transparent

Real-time status, clearer error messages and visible installation stages so users stay confident throughout setup.

Pencil sketches exploring hardware interfaces and firmware screen concepts.

Living documentation

From device discovery and configuration to diagnostics and remote maintenance.

Device List Connected devices with status, battery, signal and temperature. Search, filter, add; tabs switch between Devices, Zones and Outputs.

User List Active, pending and expired users grouped with role labels and quick actions like Resend Email.

Device Programming Status, live metrics and editable details in one layout — default states, types, timers and zone links.

HSL lightness drives both modes — readable in server rooms, garages and night-time installations.

Zone UI indicator for a door contact — the green LED shows when the door is open.

UI for the DRC50M device — switches, lights and curtains in the user's home.

Planning, wireframing, prototyping, design review, handoff — iterated with product managers and engineers.

Difficult updates Users struggle to apply patches or new versions because update mechanisms are unclear.

Uninstall and rollback Removing or reverting the installer leaves leftover files and broken configurations.

Compatibility Installed software conflicts with existing system components, causing crashes and slowdowns.

Updates Make applying patches, upgrades and hotfixes smooth and automated.

Rollback Enable clean removal or an easy rollback to a previous version.

Stability Reduce system conflicts, crashes and performance issues across environments.
