Notification Scenes

Notification Scenes

Notification scenes are a signature feature of Ava, displaying beautiful full-screen animated notifications when smart home events occur.

---

Overview

Notification scenes display full-screen animated notifications including:

• Aurora animation background
• Icon animation
• Title and description text
• Custom theme colors
• Live Home Assistant sensor values (via placeholders)

---

How It Works

Scene Loading

Scenes are loaded from the network based on language:

• Chinese: scenes_zh.json
• English: scenes_en.json

Scene files are hosted on GitHub and downloaded automatically when Ava starts. Scenes cache locally for offline use.

Triggering Scenes

Scenes are triggered through a dropdown select entity in Home Assistant:

service: select.select_option
target:
  entity_id: select.your_device_name_notification_scene
data:
  option: "Doorbell Ring"

The scene options are a dropdown list containing all available scene titles.

Built-in Scenes

Ava includes 70+ built-in scenes:

smoke	Smoke Alarm	Smoke sensor triggered
someone_home	Someone Home	Presence detection

Scene Settings

Go to Settings -> Interaction -> Scenes

Setting	Description	Default
Display Duration	How long notification shows (5-30s)	10s
Notification Sound	Play sound when showing	On
Custom Scene URL	URL to load custom scenes	Empty

Sensor Placeholders in Scene Text

You can embed live Home Assistant sensor values into a scene's title, description, and sub-description. Values refresh while the scene is on screen. Unknown or unsubscribed values render as "--".

Syntax

Syntax	Result
{{entity_id}}	Entity state
{{entity_id|attribute}}	Attribute value
{{entity_id|unit}}	unit_of_measurement (shortcut)

Example

Living room: {{sensor.living_room_temperature}}{{sensor.living_room_temperature|unit}}

This renders as: Living room: 23.5 °C

Custom Scenes

You can create your own scenes by hosting a JSON file.

JSON Format

Custom scenes must be a JSON array:

[
  {
    "id": "my_scene",
    "icon": "fa-bell",
    "iconColor": "#fbbf24",
    "title": "My Scene",
    "desc": "Description text",
    "subDesc": "Sub description",
    "themeColors": ["#f59e0b", "#d97706", "#92400e"],
    "beamColor": "rgba(251, 191, 36, 0.8)",
    "dividerColor": "rgba(251, 191, 36, 0.8)",
    "dotColor": "#fcd34d"
  }
]

Required Fields

Field	Description
id	Unique scene identifier
icon	FontAwesome icon name (e.g., fa-bell)
title	Scene title text

Optional Fields

Field	Description	Default
iconColor	Icon color (hex or Tailwind)	text-amber-200
desc	Description text	Empty

Loading Custom Scenes

Method 1: Using External URL

1. Host your JSON file on a web server
2. Go to Settings -> Interaction -> Scenes
3. Enter the URL in Custom Scene URL
4. Custom scenes will have custom_ prefix added to their IDs

Method 2: Using Home Assistant Local Files

1. Place your JSON file in Home Assistant's www folder
2. Use URL: http://your-ha-ip:8123/local/my_scenes.json
3. This allows fast loading within local network without external server

Timer and Alarm

Ava includes a timer feature with alarm sound.

Timer Sound

Stop Alarm Button
