Custom Apps and Notifications

With AWTRIX Light, you can create custom apps or notifications to display your own text and icons.

With MQTT simply send a JSON object to the topic [PREFIX]/custom/[page] where [page] is a the name of your page (without spaces).
With the HTTP API you have to set the appname in the request header (name = Appname)

JSON Properties

The JSON object has the following properties:

Key	Type	Description	Default
pos	number	defines the position of your custompage in the loop, starting at 0 for the first position. This will only apply with your first push. You cant change the position afterwards with this function
text	string	The text to display on the page.
icon	string	The icon ID or filename (without extension) to display on the page.
repeat	number	Sets how many times the text should be scrolled through the matrix before the display ends.	1
rainbow	boolean	Fades each letter in the text differently through the entire RGB spectrum.	false
duration	number	Sets how long the page should be displayed.	5
color	string	A color hex string for the text color, or an array of R,G,B values	"#FFFFFF" or [255,255,0]
hold	boolean	Set it to true, to hold your notification on top until you press the middle button or dismiss it via HomeAssistant. This key only belongs to notification.	false
sound	string	The filename of your RTTTL ringtone file (without extension).
pushIcon	number	0 = Icon doesn't move. 1 = Icon moves with text and will not appear again. 2 = Icon moves with text but appears again when the text starts to scroll again.	0
bar	array of integers	draws a bargraph. Without icon maximum 16 values, with icon 11 values

All keys are optional, so you can send just the properties you want to use.

To update a custom page, simply send a modified JSON object to the same topic. The display will be updated immediately.

You can also send a one-time notification with the same JSON format. Simply send your JSON object to "awtrixlight/notify".

Example

Here's an example JSON object to display the text "Hello, AWTRIX Light!" with the icon ID "1", in rainbow colors, for 10 seconds:

{
  "text": "Hello, AWTRIX Light!",
  "icon": "1",
  "rainbow": true,
  "duration": 10
}

Delete a custom app

To delete a custom app simply send a empty payload/body to the same topic/url. You can also use this API
