Jellyfin Control

A robust skill to control Jellyfin playback and TV power via CLI.

Features

• 🎯 One-Command Play: tv play "Breaking Bad" — turns on TV, launches Jellyfin, finds the next episode, and plays it.
• Smart Resume: Automatically finds the next unplayed episode for series.
• Resume Position: Resumes Movies/Episodes exactly where left off (with Seek fallback for LG WebOS/Tizen).
• Device Discovery: Auto-detects controllable sessions (TVs, Phones, Web).
• Remote Control: Full playback control (play, pause, stop, next, prev, volume, mute).
• TV Power & Apps: Turn TV on/off, launch apps — works with or without Home Assistant.
• Two TV Backends: Home Assistant integration or direct WebOS (LG TVs, no HA needed).
• Android TV Support: Direct ADB backend for Chromecast w/ Google TV, Nvidia Shield, Fire TV, Mi Box — no HA needed.
• Three connection modes: Home Assistant (any TV), direct WebOS (LG), direct ADB (Android TV/Fire TV).

Quick Start

Minimal setup (Jellyfin only, no TV control)

{
  "skills": {
    "entries": {
      "jellyfin-control": {
        "env": {
          "JF_URL": "http://YOUR_IP:8096",
          "JF_API_KEY": "your-api-key-here",
          "JF_USER": "your-username"
        }
      }
    }
  }
}

With Home Assistant (recommended for TV control)

{
  "skills": {
    "entries": {
      "jellyfin-control": {
        "env": {
          "JF_URL": "http://192.168.1.50:8096",
          "JF_API_KEY": "your-jellyfin-api-key",
          "JF_USER": "victor",
          "HA_URL": "http://192.168.1.138:8123",
          "HA_TOKEN": "your-ha-long-lived-token",
          "HA_TV_ENTITY": "media_player.lg_webos_tv_oled48c34la",
          "TV_MAC": "AA:BB:CC:DD:EE:FF"
        }
      }
    }
  }
}

Direct WebOS (LG TV, no Home Assistant needed)

{
  "skills": {
    "entries": {
      "jellyfin-control": {
        "env": {
          "JF_API_KEY": "your-jellyfin-api-key",
          "JF_USER": "victor",
          "TV_IP": "192.168.1.100",
          "TV_MAC": "AA:BB:CC:DD:EE:FF"
        }
      }
    }
  }
}

> First time with WebOS direct: The TV will show a pairing prompt. Accept it and save the TV_CLIENT_KEY the skill prints — add it to your env to skip the prompt next time.

Direct ADB (Android TV / Fire TV / Chromecast with Google TV, no HA needed)

{
  "skills": {
    "entries": {
      "jellyfin-control": {
        "env": {
          "JF_API_KEY": "your-jellyfin-api-key",
          "JF_USER": "victor",
          "ADB_DEVICE": "192.168.1.100:5555",
          "TV_MAC": "AA:BB:CC:DD:EE:FF"
        }
      }
    }
  }
}

> First time with ADB: Enable Developer Options on your TV (Settings → About → tap Build Number 7 times), then enable Network/USB debugging. First connection will show "Allow debugging?" on the TV — accept it. Requires adb installed on the Skill平台 host (sudo apt install adb).

Environment Variables

Jellyfin (required)

TV Control (optional — choose one backend)

Auto-detection: If TV_BACKEND is auto (default):

1. HA_URL + HA_TOKEN + HA_TV_ENTITY set → Home Assistant backend
2. ADB_DEVICE set → direct ADB (Android TV)
3. TV_IP set → direct WebOS (LG)
4. Nothing set → TV commands disabled, Jellyfin-only mode

Usage

🎯 One-Command Play (the magic)

Turn on TV → launch Jellyfin → find next episode → play it. All in one command:

node skills/jellyfin-control/cli.js tv play "Breaking Bad"
js tv play "The Matrix"

The skill validates the content exists BEFORE turning on the TV (fail fast).

Resume / Play Smart

If TV and Jellyfin are already running:

js resume "Breaking Bad"
js resume "Matrix" --device "Chromecast"

TV Control

js tv on           # Turn on (Wake-on-LAN)
js tv off          # Turn off
js tv launch       # Launch Jellyfin app
js tv launch com.webos.app.hdmi1  # Launch specific app
js tv apps         # List installed apps

Remote Control

Search Content

js search "Star Wars"

Library Stats & Scan

js scan            # requires admin API key

User History (requires admin API key)

js history jorge --days 7

Choosing a TV Backend

Recommendation:

• Already have Home Assistant? → Use HA backend (most versatile, any TV brand)
• LG WebOS TV, no HA? → Use direct WebOS backend
• Android TV / Fire TV / Chromecast with Google TV, no HA? → Use direct ADB backend
• No smart TV control needed? → Skip TV config, resume works if Jellyfin app is already open

Security Notes

• API keys only in skill-platform.json env — never in workspace files, .env files, or markdown docs.
• HA tokens are long-lived and powerful. Create a dedicated HA user with limited permissions if possible.
• TV_CLIENT_KEY (WebOS) is sensitive — it allows full control of your TV. Treat it like a password.
• ADB access grants full control of your Android TV. Ensure your network is secured — anyone on the same network could connect via ADB if debugging is enabled.
• Admin operations (history, scan) require an admin-level Jellyfin API key and will fail gracefully with 403 if permissions are insufficient.

Architecture

• lib/jellyfin.js — Jellyfin REST API (auth, search, sessions, playback control)
• lib/tv.js — TV control abstraction (HA backend, WebOS backend, Wake-on-LAN)
• cli.js — User-friendly CLI with all commands

Workflow: Agent says "Play Star Trek on TV"

Agent → cli.js tv play "Star Trek"
         │
         ├── 1. Search Jellyfin for "Star Trek" (fail fast)
         ├── 2. Find next unplayed episode
         ├── 3. Wake-on-LAN → TV turns on
         ├── 4. Wait 10s for boot
         ├── 5. Launch Jellyfin app (HA or WebOS)
         ├── 6. Wait 8s for session registration
         ├── 7. Find Jellyfin session (retry 3x)
         └── 8. Play episode on session
