Behavior

Best for connectivity, alarms, relay state and heartbeat indicators.
Tiny footprint makes it useful in dense control surfaces.
Can be color-coded per data stream.

Firmware contract

Write 0/1 for state or 0-255 for brightness-like emphasis.

On the app side this widget snaps to the 8-column square grid and uses both resizing. Its raw type is LED and the matching icon token in the app is lightbulb.fill.

Pin support: A configured pin is required before the widget becomes meaningful.

Transmission: Payload format depends on the widget type and the selected pinType.

Use the app-side widget config sheet to tune behavior per widget type.
