Universal Notifier è un componente custom per Home Assistant che centralizza e potenzia la gestione delle notifiche.

Trasforma semplici automazioni in un sistema di comunicazione "Smart Home" che conosce l'ora del giorno, rispetta il tuo sonno (DND), saluta in modo naturale e gestisce automaticamente il volume degli assistenti vocali.

✨ Caratteristiche Principali

• Piattaforma Unificata: Un solo servizio (universal_notifier.send) per Telegram, App Mobile, Alexa, Google Home, ecc.
• Notifiche personalizzate a più destinatari (ad esempio, notifica di allarme sia a Telegram che ad Alexa)
• Voce vs Testo: Distingue automaticamente tra messaggi da leggere (con prefissi [Jarvis - 12:30]) e messaggi da pronunciare (solo testo pulito).
• Time Slots & Volume Smart: Imposta volumi diversi per Mattina, Pomeriggio, Sera e Notte. Il componente regola il volume prima di parlare.
• Do Not Disturb (DND): Definisci un orario di silenzio per gli assistenti vocali. Le notifiche critiche (priority: true) passano comunque.
• Saluti Casuali: "Buongiorno", "Buon pomeriggio", ecc., scelti casualmente da liste personalizzabili.
• Gestione Comandi: Supporto nativo per comandi Companion App (es. TTS, command_volume_level) inviati in modalità "RAW".

Universal Notifier is a custom Home Assistant component that centralizes and enhances notification management.

It transforms simple automations into a "Smart Home" communication system that knows the time of day, respects your sleep (Do Not Disturb - DND), greets naturally, and automatically manages the volume of voice assistants.

✨ Key Features

• Unified Platform: A single service (universal_notifier.send) for Telegram, Mobile App, Alexa, Google Home, etc.
• Personalized notifications to several targets (i.e. alarm notification to both Telegram and Alexa)
• Voice vs. Text: Automatically differentiates between messages to be read (with prefixes like [Jarvis - 12:30]) and messages to be spoken (clean text only).
• Smart Time Slots & Volume: Set different volumes for Morning, Afternoon, Evening, and Night. The component adjusts the volume before speaking.
• Do Not Disturb (DND): Define quiet hours for voice assistants. Critical notifications (priority: true) will still go through.
• Random Greetings: "Good morning," "Good afternoon," etc., chosen randomly from customizable lists.
• Command Handling: Native support for Companion App commands (e.g., TTS, command_volume_level) sent in "RAW" mode.

🔗 Prerequisites

Click me

Before configuring Universal Notifier, ensure you have installed and set up the underlying notification integrations you plan to use:

• Google Home / TTS: Install the Google Translate Text-to-Speech (TTS) integration to enable voice announcements on Google Assistant devices.
• Alexa / Echo Devices: Install the Alexa Media Player Custom Component (via HACS) to allow Home Assistant to send announcements and set volume on Echo devices.
• Telegram: Configure and install the Telegram Bot integration to send visual messages.
• Mobile App: Ensure the Mobile App integration is active and configured for your devices (this is usually set up automatically when you log in via the app).

This component acts as a "router"; it must have the target services available to function correctly.

📝 Usage Examples

Click me

1. Standard Notification (Automatic Volume)

If sent at 3:00 PM, it will use the afternoon volume (0.60). If sent at 2:00 AM (DND is active), Alexa will be skipped, but Telegram will receive the message.

action: universal_notifier.send
data:
  message: "The laundry is finished."
  targets:
    - alexa_living_room
    - telegram_admin

2. Priority Notification (Bypasses DND and sets Volume to 90%)

Use the priority flag for critical alerts.

action: universal_notifier.send
data:
  title: "CRITICAL ALERT"
  message: "Water leak detected, valve closed!"
  priority: true        # <--- FORCES SENDING AND MAX VOLUME (0.9)
  skip_greeting: true   # <--- Avoids greetings like "Good night" during an alarm
  targets:
    - alexa_living_room
    - telegram_bot_media
    - gh_kitchen

3. Companion App Commands (Raw Messages)

If the message is a recognized command (like "TTS") or starts with command_, greetings and prefixes are automatically stripped.

action: universal_notifier.send
data:
  message: "TTS" # The component sends "TTS" RAW, without prefixes.
  targets:
    - my_android
  target_data:
    my_android:
      tts_text: "The postman is at the door."
      media_stream: alarm_stream_max
      clickAction: /lovelace/main

4. Multi target
