# RelayTV – Home Assistant Integration

RelayTV transforms Home Assistant into a **programmable local media automation engine**.

It exposes your RelayTV server as a `media_player` (plus services), supports queue-based playback, and makes it easy to drive **local HDMI playback** from automations (doorbells, sensors, schedules, scenes, and AI).

> Tip: The YAML below uses the `relaytv.*` service names as examples. If your integration exposes slightly different names/fields, keep the **automation patterns** and adjust the service calls accordingly.

# 🚀 What RelayTV Enables Today

## 🎬 Media Player Control
- `media_player` entity support
- Play / pause / stop / seek / volume
- Queue management
- Resume playback support (where implemented)
- Local HDMI playback
- yt-dlp powered “smart URL” stream resolution

---

# ⭐ Key Mobile UX Feature: “Share to Home Assistant” → Play / Enqueue

One of the best day-to-day workflows is using your phone like a “remote link picker”:

1. On iOS/Android, **share a link** (YouTube, Twitch, a direct stream URL, etc.)
2. Choose **Home Assistant** from the share sheet
3. Home Assistant fires an event (`mobile_app.share`) containing the shared `url` or `text`
4. An automation can then **play now** or **enqueue** on RelayTV

This feels *incredible* in practice: you browse normally on your phone, tap Share, and your TV starts playing.

> Pro tip: Use the HA UI automation editor to duplicate this automation into variants:
> - “Share → Play Now (Living Room)"
> - “Share → Enqueue (Bedroom)"
> - “Share → Ask which TV” (roadmap: actionable notification picker)

# ✅ Automation Examples (YAML)

## 0) Drop-in: Share to Home Assistant → Play Now (Mobile)

**What it does:** When you share a link to the Home Assistant app, this plays it immediately on RelayTV.

- Trigger: `mobile_app.share`
- Uses: `trigger.event.data.url` (preferred) or `trigger.event.data.text`

```yaml
alias: RelayTV - Mobile Share -> Play Now
mode: queued
trigger:
  - platform: event
    event_type: mobile_app.share
action:
  - variables:
      shared_url: >-
        {{ trigger.event.data.url
           if trigger.event.data.url is defined
           else (trigger.event.data.text if trigger.event.data.text is defined else '') }}
  - condition: template
    value_template: "{{ shared_url | length > 0 }}"
  - service: relaytv.play_now
    target:
      entity_id: media_player.relaytv_living_room
    data:
      url: "{{ shared_url }}"
  - service: notify.notify
    data:
      title: "RelayTV"
      message: "Playing: {{ shared_url }}"
```

### Variant: Mobile Share → Enqueue Instead of Play Now

```yaml
alias: RelayTV - Mobile Share -> Enqueue
mode: queued
trigger:
  - platform: event
    event_type: mobile_app.share
action:
  - variables:
      shared_url: >-
        {{ trigger.event.data.url
           if trigger.event.data.url is defined
           else (trigger.event.data.text if trigger.event.data.text is defined else '') }}
  - condition: template
    value_template: "{{ shared_url | length > 0 }}"
  - service: relaytv.enqueue
    target:
      entity_id: media_player.relaytv_living_room
    data:
      url: "{{ shared_url }}"
  - service: notify.notify
