Context

A light is simple. A room full of lights is not.

01

Fixture

One controllable light or lighting unit.

02

Channel

An independently adjustable output.

03

Scene

A saved combination of light settings.

The intent

Set the room once.
Bring it back in a tap.

Problem

The same app. Different kinds of light.

A single-channel fixture and a colour-temperature fixture need different controls. Shared devices also need clear availability.

Why this direction

The interface should reflect the light that is connected, and explain why a command is unavailable.

Structure

Solution / 01

A useful home, from the first tap.

Fixtures and scenes are easy to reach. Setup starts from an explicit add action.

Design choice

Keep frequent controls distinct from guidance and updates.

Add a fixture
Solution / 02

Only the controls this fixture needs.

Single-channel, dual-channel and temperature controls reflect the connected device.

Design choice

Do not make people translate hardware differences into generic controls.

Solution / 03

A blocked action needs an explanation.

Empty inputs, conflicting details and devices in use should explain what to change next.

Design choice

Feedback belongs beside the action that needs attention.

Solution / 04

Save the setting. Repeat the feeling.

Choose the fixtures, name the scene and keep it ready to use again.

Design choice

Selection comes before naming, so the scene has a clear scope.
