| description | Control the device's RGB light when the user asks for a SPECIFIC color (e.g. "yellow", "red", "yellow", "red", "turn on color X", "enable X light"), an LED effect, or turning LEDs off. Do NOT use for ambiance/activity lighting (use Scene) or emotion expression (use Emotion). |
LED Control
Quick Start
Control the device's RGB light directly. Use this skill only when the user requests a specific color, effect, or to turn LEDs off.
Workflow
- Determine the user's intent:
- Specific color ->
[HW:/led/effect/stop:{}][HW:/led/solid:{"color":[R,G,B]}]
- Two or more colors / mix / gradient ->
[HW:/led/effect/stop:{}][HW:/led/paint:{"colors":[[R,G,B],[R,G,B]],"gradient":true}]
- Effect ->
[HW:/led/effect:{"effect":"name","color":[R,G,B],"speed":1.0}]
- Turn off ->
[HW:/led/off:{}]
- Place markers at start of reply — the device fires them in order before TTS
- 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: "Change to cyan purple" / "mix blue and pink" / "gradient from red to orange"
Output: [HW:/led/effect/stop:{}][HW:/led/paint:{"colors":[[0,200,200],[150,0,255]],"gradient":true}] Cyan-to-purple gradient 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 — the device 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].
Multi-color / gradient (stop effect first)
[HW:/led/effect/stop:{}][HW:/led/paint:{"colors":[[0,200,200],[150,0,255]],"gradient":true}] Cyan-to-purple gradient!
colors: list of RGB gradient stops (2+ colors), blended smoothly across the whole stripgradient: true is REQUIRED — without it the colors paint only the first N pixels and the rest of the strip keeps its old color- Works with 3+ stops too:
{"colors":[[255,0,0],[255,220,0],[0,200,80]],"gradient":true} = red -> yellow -> green
Effect
[HW:/led/effect:{"effect":"breathing","color":[255,180,100],"speed":0.5}] Breathing warm glow.
effect (required): effect name from table belowcolor (optional): RGB arrayspeed (optional): 0.1 (slow) to 5.0 (fast), default 1.0duration_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 suggestions

| Warm white | [255, 180, 100] |
| Orange | [255, 100, 0] |

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
- ALWAYS include the JSON body, even for no-argument commands. Every marker is
[HW:/path:{...}] — for commands that take no arguments the body is the empty object {}. Emit [HW:/led/off:{}] and [HW:/led/effect/stop:{}], NEVER the bodyless [HW:/led/off] or [HW:/led/effect/stop]. A marker without :{...} is malformed and the device silently drops it — the light will NOT turn off.
- The marker is NOT a markdown link. Never wrap it as
[some text](HW:/led/off:{}) — emit the plain marker [HW:/led/off:{}] followed by your sentence as normal text.
- "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]}].
- Two or more colors at once =
/led/paint with "gradient":true. /led/solid takes exactly ONE color — never try to express "cyan purple" as a single blended RGB; paint a gradient instead.
- 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.
