led-control

# 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 1. Determine the user's intent: - Specific color -> `[HW:/led/solid:{"color":[R,G,B]}]` - Two or more colors / mix / gradient -> `[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:{}]` 2. Place markers at start of reply — the device fires them in order before TTS 3. Confirm the action to the user ## Examples Input: "Make it purple" / "turn on purple" Output: `[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/solid:{"color":[255,220,0]}]` Yellow light on! Input: "Turn on red light" / "set red" / "switch to red" / "red light" Output: `[HW:/led/solid:{"color":[255,0,0]}]` Red light on! Input: "Turn on white light" / "set white" / "white light" Output: `[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/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 (automatically stops the current effect) ``` [HW:/led/solid:{"color":[255,220,0]}] Yellow light on! ``` Color is an RGB array `[R, G, B]`. ### Multi-color / gradient (automatically stops the current effect) ``` [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 strip - `gradient: 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 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 suggestions | Color name | Color (RGB) | |---|---| | White | `[255, 255, 255]` | | Yellow | `[255, 220, 0]` | | 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 - **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/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. - **Solid and paint stop effects automatically.** Their HAL endpoints stop the running effect before updating the strip; do not add a separate stop marker. Keep `/led/effect/stop` for an explicit stop-only request. - **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. ## Output Template ``` [HW:/led/solid:{"color":[100,50,200]}] Purple light on. ``` Examples: - `[HW:/led/solid:{"color":[100,50,200]}] Purple light on.` - `[HW:/led/effect:{"effect":"breathing","color":[255,180,100],"speed":0.5}] Warm breathing light on.` - `[HW:/led/off:{}] Lights off.`
