# MQTT Awtrix 3 Binding

This binding allows you to control Awtrix 3 (formerly Awtrix Light) LED matrix displays via MQTT. Awtrix 3 is a firmware for a 32x8 LED matrix display that can show various information like time, weather, notifications and custom text/graphics. The most popular choice for a device that supports the Awtrix 3 firmware is the Ulanzi tc0001 clock.

# Supported Things

This binding supports two types of things:

Thing Type	Description
`awtrix-clock` (Bridge)	Represents an Awtrix 3 display device. Acts as a bridge for apps.
`awtrix-app`	Represents an app running on the Awtrix display. Apps can show text, icons, notifications, etc.

The binding was tested with the Ulanzi tc0001 clock.

# Discovery

The binding can automatically discover Awtrix 3 devices that publish their status to the configured MQTT broker. Make sure to use a mqtt prefix that starts with awtrix for discovery to work. It is however recommended to use a prefix with two topic levels, for example awtrix/clock1 so that you can discover and control multiple devices. Once a device is discovered, it will appear in the inbox. There is no need to trigger a discovery scan manually. Default Awtrix apps can also be discovered if discoverDefaultApps is enabled on the bridge. This is however not recommended as the default apps cannot be controlled with this binding.

# Binding Configuration

The Awtrix 3 binding does not offer any binding configuration parameters.

# Thing Configuration

# Bridge Configuration (`awtrix-clock`)

Parameter	Description	Default	Required
`basetopic`	The MQTT base topic for the Awtrix device	"awtrix"	Yes
`appLockTimeout`	Timeout in seconds before releasing the lock to a selected app and returning to normal app cycle (see App Configuration for more details).	10	Yes
`discoverDefaultApps`	Enable discovery of default apps. Since default apps cannot be controlled by this binding this should usually be disabled.	false	Yes
`lowBatteryThreshold`	Battery level threshold for low battery warning.	25	Yes

# App Configuration (`awtrix-app`)

Parameter	Description	Default	Required
`appname`	Name of the app	-	Yes
`useButtons`	Enable button control for this app	false	No

When you enable the button control for an app, you can lock the app to the display by pushing the select button on the clock device. A red indicator will be shown while the app is locked and will start to blink shortly before the lock ends. The lock will last for the appLockTimeout set for the bridge. As long as the app is locked the normal app cycle is disabled and you can control the app by pressing the left and right buttons or the select button on the clock device. Pressing a button while the app is locked will reset the lock timeout to the value set for appLockTimeout. Left and right button presses will emit button events on the clock itself and the selected app. The button events can be used by rules to change the displayed app or perform any other actions (for example change the text color of the app or skip the current song playing on your audio device).

# Channels

# Bridge Channels (`awtrix-clock`)

Channel	Type	Read/Write	Description
`app`	String	R	Currently active app: Will show the name of the app that is currently shown on the display.

# Text Color Tags

The text channel supports inline color formatting using simple HTML-like font color tags. This allows you to display text with multiple colors in a single app.

# Syntax

Use the following format to apply colors to specific parts of your text:

<font color="#RRGGBB">colored text</font>

Where RRGGBB is a 6-digit hexadecimal color code (e.g., FF0000 for red, 00FF00 for green, 0000FF for blue).

# Examples

// Multiple colored segments - "Hello" and "in" will use the color from the color channel, "World" and "Color" will use the specified colors
Custom_Text.sendCommand('Hello <font color="#FF0000">World</font> in <font color="#00FF00">Color</font>')

// All text in custom color
Custom_Text.sendCommand('<font color="#FF6600">Temperature: 25°C</font>')

# Important Notes

Default color: Text outside of <font> tags will be displayed in the color defined by the color channel.
Text effects disabled: When color tags are used, the blink, fade, and rainbow effects are automatically disabled, as each text segment has its own color. The gradient-color channel is also ignored.
Tags cannot be nested: <font> tags must not be placed inside other <font> tags. Nesting is not supported and will result in incorrect parsing.
Case-insensitive hex values: Both uppercase and lowercase hex values are supported (e.g., #FF0000 or #ff0000).
Malformed tags: If a tag is malformed (e.g., missing closing tag), the parser will gracefully handle it by applying the default color.

    var progress = (Washing_Machine_Progress.state as Number).intValue
    
    // Update custom app with progress bar
    Custom_Text.sendCommand("Washing")
    Custom_Icon.sendCommand("washing-machine")
    Custom_Progress.sendCommand(progress)
    Custom_ProgressColor.sendCommand("0,255,0")  // Green progress bar
    
    if (progress == 100) {
        // Play sound when done
        getActions("mqtt.awtrixlight", "mqtt:awtrix-clock:myBroker:myAwtrix").playSound("complete")
    }
end

These rules demonstrate:

Using indicators to show battery status
Creating custom notifications with icons and colors
Playing RTTTL melodies and sound files
Displaying progress bars
