Discord


The Discord service is a platform for the notify integration. This allows integrations to send messages to the user using Discord.

Prerequisites

Creating a Discord Application

In order to create a bot user a Discord Application is required. Go to the Discord My Apps page and create a new application.

When setting up the application you can use this icon.

Once the application is ready, create a bot user (Create a Bot User).

Retrieve the Application ID from the ‘General Information’ section and the (hidden) Token of your bot for later.

The name you give your application on the Discord My Apps page will determine the name of the notify service. For example: if you enter “Discord Chat”, the service will be named notify.discord_chat.

Setting up the bot

Bots can send messages to servers and users or attach locally available images. To add the bot to a server you are an admin on, use the Application ID you noted above, found on the Discord My Apps page.

Next, decide what permissions your bot will have within your server. Under the ‘Bot’ section, select the permissions you want to grant and copy the permissions integer from the bottom field.

Now use the Discord Authorization page with the Application ID of your application and the Permissions Integer.

https://discordapp.com/api/oauth2/authorize?client_id=[APPLICATION_ID]&scope=bot&permissions=[PERMISSIONS_INTEGER]

Wait for the confirmation which should say “Authorized”.

Once the bot has been added to your server, get the channel ID of the channel you want the bot to operate in. Open Discord and go to User Settings > Advanced > Enable Developer Mode. User settings can be found next to your username in Discord.

Right click channel name and copy the channel ID (Copy ID).

This channel or a user ID has to be used as the target when calling the notification service. Multiple channel or user IDs can be specified, across multiple servers or direct messages.

Add Discord integration to Home Assistant

Configuration

To add the Discord integration to your Home Assistant instance, use this My button:

When adding the Discord integration you will be asked for an API Key. Enter the hidden Token of your bot to link your Discord integration to the bot you created and allow Home Assistant to send messages as that bot.

Example service call

- service: notify.discord
  data:
    message: "A message from Home Assistant"
    target: ["1234567890", "0987654321"]
    data:
      images: 
      - "/tmp/garage_cam"
      - "/tmp/garage.jpg"

Example service call with attachments sourced from remote URLs

- service: notify.discord
  data:
    message: "A message from Home Assistant"
    target: ["1234567890", "0987654321"]
    data:
      verify_ssl: False
      urls: 
      - "https://example.com/image.jpg"
      - "https://example.com/video.mp4"

Note that verify_ssl defaults to True, and that any remote hosts will need to be in your allowlist_external_urls list. Discord limits attachment size to 8MB, so anything exceeding this will be skipped and noted in the error log.

Notes

You can tag any user inside a channel by using their user ID in the message like so: <@userid> replacing userid with the ID you copied. To get the user ID right click on the user name to copy the ID like you did for the channel ID up above.

To use notifications effectively, please see the getting started with automation page.

Images are uploaded to Discord when a message is sent. As such, a local path to the image is required (i.e., /config/www/garage.jpg as opposed to /local/garage.jpg), and updating an image after sending it in a message will not update the message in Discord.
