BACKGROUND

Leksa is a smart lighting automation application designed in collaboration with the R&D Team at 44 Volts Designs. The goal was to create a seamless interface that bridges hardware and software, allowing users to add fixtures, control lighting parameters, and build customizable scenes with ease. Unlike off-the-shelf apps, Leksa had to align with custom-built hardware, which meant designing flows that simplified technical complexity into intuitive, everyday interactions.

OBJECTIVES / DESIGN GOALS

Simplify fixture setup for non-technical users.
Provide intuitive controls for brightness, color, and temperature.
Enable flexible scene creation for home + professional use.
Ensure scalability for future fixtures and hardware updates.

MY APPROACH TO THIS PROBLEM

Collaboration With R&D

Wireframes & Interaction Flows

High-Fidelity UI & Design System

Validation With Real Fixtures

1. COLLABORATION WITH R&D TEAM

Defining the non-negotiables:

Principle	Why It Mattered
Frictionless Pairing	First-time setup had to feel effortless, else users drop off immediately.
State Sync Everywhere	App, cloud, and fixtures always aligned to build trust.
Real-Time Feedback	Immediate response (<300 ms) builds confidence in controls.
Conflict Handling	Prevent confusion when multiple users control the same fixture.
Offline Resilience	Lights should still work when Wi-Fi drops — no excuses.
Clear Recovery	Errors explained in human terms, with retries and diagnostics.
Scalability	Works for 3 fixtures at home or 300 on stage.
Accessibility & Safety	Dark UI, high contrast, safe brightness floors, one-hand controls.

2. WIREFRAMES & INTERACTION FLOW

Before jumping into high-fidelity screens, I mapped out the user journey and sketched wireframes to validate the flow with the R&D team. The focus was on clarity: from onboarding to adding fixtures to creating scenes — every step needed to feel effortless and logical.

The above wireframes and flow were shared with the client and R&D team for alignment before moving into high-fidelity design. This ensured every edge case was covered early, reducing rework later.
