# Spotify Voice Assistant for Home Assistant

**Voice-controlled Spotify playback using natural language.** Just say "Play Coldplay on the kitchen speaker" and your music starts playing - no complex YAML patterns, no cookie authentication, just works.

## The Problem

Want to control Spotify with your voice in Home Assistant? You'll quickly hit these issues:

- **Spotcast** requires cookie authentication (`sp_dc`, `sp_key`) which breaks frequently with "serverTime" errors
- **Music Assistant** requires running a separate music server - heavyweight for just Spotify
- **SpotifyPlus** is feature-rich but complex to set up for simple voice commands
- **Custom Sentences** require rigid YAML patterns - "Play {artist} on {speaker}" instead of natural language
- **Built-in Spotify integration** has no search service for voice assistants to use
- **Other integrations return wrong artists** - Standard Spotify search returns personalized recommendations instead of exact matches

## The Solution

A lightweight integration designed specifically for voice assistants that:

✅ **Natural language from day one** - "Play Coldplay" not "play artist equals Coldplay"
✅ **Zero additional authentication** - Reuses your existing Home Assistant Spotify OAuth
✅ **Exact match artist search** - Finds Coldplay when you ask for Coldplay, not recommendations
✅ **Works with any Spotify Connect device** - WiiM, Sonos, Google Cast, Echo, whatever you have
✅ **Under 120 lines of code** - Simple, maintainable, easy to understand
✅ **Voice assistant ready** - Complete Extended OpenAI Conversation examples included

## Quick Start

Say goodbye to complex configurations. Get voice-controlled music in 3 steps:

### 1. Install Prerequisites

```
</details>

Add this to your Extended OpenAI Conversation system prompt:

```
Music Playback:
- When asked to play music, follow this two-step process: 1) Call search_spotify to get the Spotify URI, 2) Call play_music with the URI and media player entity
- Available media players: [list your Spotify Connect devices here, e.g., "media_player.kitchen_speaker, media_player.living_room_sonos"]
- Parse commands like "Play {Artist/Album/Track}" and determine the media type automatically
- For playback control (pause, skip, volume), use the control_playback function
```

### Done! Try It

- "Play Coldplay on the kitchen speaker"
- "Play the album Parachutes"
- "Play Yellow by Coldplay"
- "Pause the music"
- "Skip to the next track"
- "Set volume to 50%"

## Compatible Speakers

This integration works with **any Spotify Connect-compatible device**:

### Tested & Verified
- **WiiM Audio Pro** (and all WiiM speakers)
- **Sonos speakers** (all models with Spotify)
- **Google Nest/Home speakers**
- **Amazon Echo with Spotify**

### Should Work (Spotify Connect Compatible)
- **Smart Speakers:**
  - Apple HomePod (with Spotify app)
  - Bose Home Speaker series
  - JBL Link series
  - Harman Kardon Citation series
  - Bang & Olufsen Beosound series

- **Streaming Devices:**
  - Chromecast Audio
  - Roku with Spotify channel
  - Fire TV with Spotify
  - Apple TV with Spotify app

- **AV Receivers:**
  - Denon HEOS-enabled receivers
  - Yamaha MusicCast receivers
  - Marantz NR/SR series
  - Pioneer VSX series with Spotify

- **DIY Solutions:**
  - Raspberry Pi with [Raspotify](https://github.com/dtcooper/raspotify)
  - Raspberry Pi with [Spotifyd](https://github.com/Spotifyd/spotifyd)
  - Any Linux/Mac/Windows computer running Spotify

- **Mobile Devices:**
  - Phones/tablets running Spotify app (for testing)

### Requirements
- **Spotify Premium account** (Spotify Connect requires Premium)
- **Device must show up in Home Assistant** as a `media_player` entity
- **Device must support Spotify Connect** (check manufacturer specs)

**Note:** If your device runs Spotify and shows up in Home Assistant's integrations, it will work with this integration.

## How It Works

### The Two-Step Process

**1. Search Spotify**
```
You: "Play Coldplay"
LLM: Calls search_spotify(query="Coldplay", type="artist")
Response: {"uri": "spotify:artist:4gzpq5DPGxSnKTe4SA8HAU", "name": "Coldplay"}
```

**2. Play on Device**
```
LLM: Calls play_music(uri="spotify:artist:...", media_player="media_player.kitchen_speaker")
Result: Music starts playing
```

### Exact Match Artist Search

When searching for artists, this integration uses smart matching to avoid Spotify's personalization issues:

1. Queries Spotify for top 10 artist results
2. Checks each result for exact name match (case-insensitive)
3. Returns exact match if found, otherwise returns first result
4. Logs match type (exact/first) for debugging

**Why this matters:** Standard Spotify search prioritizes personalized recommendations. If you search "Coldplay," you might get Taylor Swift if you listen to her frequently. Our exact matching ensures you get Coldplay when you ask for Coldplay.

### No Additional Authentication

The integration leverages Home Assistant's official Spotify integration:
- Uses existing OAuth tokens
- No cookies to manage (`sp_dc`, `sp_key`)
- No tokens to refresh
- Works as long as your Spotify integration works

### Performance Optimization

The integration includes smart caching for optimal performance:

**First search:** ~1.6-5.6ms (finds and caches Spotify client)
**Subsequent searches:** ~0.1ms (uses cached client)
**Performance gain:** 15-50x faster on repeated searches

**Cache Features:**
- Automatically validates cached client on every call
- Self-invalidates when Spotify integration is reloaded or removed
- Manual cache clearing available via `spotify_search.clear_cache` service

The cache is module-level and process-scoped, so it clears automatically on Home Assistant restart.

## Advanced Usage

### Developer Tools Testing

Test the search service directly:

```yaml
service: spotify_search.search
data:
  query: "Coldplay"
  type: "artist"
```

Response:
```json
{
  "uri": "spotify:artist:4gzpq5DPGxSnKTe4SA8HAU",
  "name": "Coldplay",
  "type": "artist"
}
```

### Use in Automations

```yaml
automation:
  - alias: "Morning Music"
    trigger:
      - platform: time
        at: "07:00:00"
    action:
      - service: spotify_search.search
        response_variable: artist_result
        data:
          query: "Chillhop Music"
          type: "artist"
      - service: media_player.play_media
        target:
          entity_id: media_player.kitchen_speaker
        data:
          media_content_id: "{{ artist_result.uri }}"
          media_content_type: "music"
```

### Clear Cache Service

If you experience issues after removing or re-adding the Spotify integration, you can manually clear the cached client:

```yaml
service: spotify_search.clear_cache
```

The cache automatically invalidates when the Spotify integration is reloaded, so manual clearing is rarely needed.

### Debug Logging

Enable detailed logging in `configuration.yaml`:

```yaml
logger:
  default: info
  logs:
    custom_components.spotify_search: debug
```

This shows search queries, match types (exact vs. first result), and any errors.

## Troubleshooting

### "No Spotify media player entity found"

**Cause:** Official Spotify integration not configured.

**Solution:**
1. Settings > Integrations > Add Integration
2. Search for "Spotify"
3. Complete OAuth authentication
4. Verify `media_player.spotify_*` entity appears
5. Restart Home Assistant

### "Spotify entity does not have a coordinator"

**Cause:** Spotify integration hasn't fully initialized.

**Solution:** Wait 30 seconds after HA starts, or restart Home Assistant.

### Voice commands not working

**Cause:** Extended OpenAI Conversation functions not configured.

**Solution:**
1. Verify functions are added to Extended OpenAI settings
2. Check system prompt includes music playback instructions
3. Test search service manually in Developer Tools
4. Check Home Assistant logs for errors

### Wrong artist/song playing

**Cause:** Exact match not found in top 10 results.

**Solution:**
- Use more specific query: "Coldplay band" instead of just "Coldplay"
- Check search result in Developer Tools first
- Try searching by track or album if artist search fails

### Music won't play on speaker

**Cause:** Device not Spotify Connect compatible or not in HA.

**Solution:**
1. Verify device supports Spotify Connect (check manufacturer site)
2. Check device shows in Settings > Integrations
3. Test playing Spotify directly to device from Spotify app
4. Verify Spotify Premium account is active
