name	led-control
description	Control the 64-pixel WS2812 RGB LED strip when the user asks for a SPECIFIC color (e.g. "yellow", "red", "yellow", "red", "turn on color X", "enable X light"), LED effect, pixel painting, or turning LEDs off. Do NOT use for ambiance/activity lighting (use Scene) or emotion expression (use Emotion).

LED Control

Quick Start

Control the lamp's 64-pixel WS2812 RGB LED strip directly. Use this skill only when the user requests a specific color, effect, pixel pattern, or to turn LEDs off.

Workflow

1. Determine the user's intent:
   • Specific color -> [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[R,G,B]}]
   • Effect -> [HW:/led/effect:{"effect":"name","color":[R,G,B],"speed":1.0}]
   • Turn off -> [HW:/led/off:{}]
2. Place markers at start of reply — Lamp fires them in order before TTS
3. Confirm the action to the user

Examples

Input: "Make it purple" / "turn on purple" Output: [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[100,50,200]}] I've set the LEDs to purple.

Input: "Turn on yellow light" / "set yellow" / "switch to yellow" / "yellow light" Output: [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[255,220,0]}] Yellow light on!

Input: "Turn on red light" / "set red" / "switch to red" / "red light" Output: [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[255,0,0]}] Red light on!

Input: "Turn on white light" / "set white" / "white light" Output: [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[255,255,255]}] White light on!

Input: "Do a breathing light with warm color" Output: [HW:/led/effect:{"effect":"breathing","color":[255,180,100],"speed":0.5}] Breathing effect started with a warm glow.

Input: "Rainbow mode!" Output: [HW:/led/effect:{"effect":"rainbow","speed":1.0}] Rainbow effect is running!

Input: "Turn off the lights" Output: [HW:/led/off:{}] LEDs are off.

Input: "I want to relax" / "reading mode" / "goodnight" Output: Do NOT use this skill. Use Scene skill instead.

Input: Conversational reply needing emotion Output: Do NOT use this skill. Use Emotion skill instead.

How to Control LEDs

No exec/curl needed. Use inline markers at start of reply — Lamp fires them in order:

Solid color (stop effect first)

[HW:/led/effect/stop:{}][HW:/led/solid:{"color":[255,220,0]}] Yellow light on!

Color is an RGB array [R, G, B].

Effect

[HW:/led/effect:{"effect":"breathing","color":[255,180,100],"speed":0.5}] Breathing warm glow.

• effect (required): effect name from table below
• color (optional): RGB array
• speed (optional): 0.1 (slow) to 5.0 (fast), default 1.0
• duration_ms (optional): auto-stop after N ms

Turn off / stop effect

[HW:/led/off:{}] LEDs off.
[HW:/led/effect/stop:{}]

Available effects

Effect	Description	Best for
breathing	Slow fade in/out with given color	Relaxation, idle ambient, meditation
candle	Warm flickering like a real candle	Cozy evening, romantic mood
rainbow	Hue cycle across all pixels	Fun, party, showing off
notification_flash	3 quick flashes then auto-stops	Alerts, timer done, reminders
pulse	Radial brightness wave from center	Attention, heartbeat, alive feeling

Color name	Color (RGB)

Warm white	[255, 180, 100]
Orange	[255, 100, 0]
Red	[255, 0, 0]
Green	[0, 200, 80]
Blue	[0, 150, 255]
Purple	[100, 50, 200]
Pink	[255, 80, 150]

Error Handling

• If the API returns an error or is unreachable, inform the user: "I couldn't control the LEDs right now. The hardware service may be unavailable."
• If the user requests an unknown effect name, pick the closest match from the available effects table or tell the user which effects are available.

Rules

• "Turn on color X" / "set light X" / "change color X" = THIS skill. Any request naming a color (yellow, red, green, purple, white, orange, pink…) routes here — NOT to Emotion or Scene. Emotion yellow/happy is for YOUR feelings, not user's lighting request.
• NEVER use /led-color or /led/color for setting color — these endpoints do NOT exist. Always use [HW:/led/effect/stop:{}][HW:/led/solid:{"color":[R,G,B]}].
• Stop effect before solid. Always call /led/effect/stop before /led/solid. A running effect thread overwrites solid every 40ms — skipping the stop causes the color to flicker and revert.
• Solid colors = full brightness. For dim/ambient lighting, use the Scene skill instead.
• Effects run until stopped (unless duration_ms is set). Starting a new effect auto-stops the previous one.
• /led/off also stops any running effect.
• For "make it cozy" or "candle light" -> use candle effect, NOT a static orange color.
• For "breathing" or "pulsing" requests -> use the matching effect.
• Combine effects with low speed (0.3-0.5) for calm moods, high speed (2.0-3.0) for energy.
• Do NOT use for activity/ambiance lighting (sleeping, relaxing, reading, focus, movie) -> use Scene skill.
• Do NOT use for expressing emotion -> use Emotion skill.
