OctoPrint-DiscordRemote

DiscordRemote is a plugin allowing Octoprint to send notifications to a Discord channel. The plugin acts as a Discord bot, which allows it to listen on the channel and respond to commands to control the printer. There is a small amount of configuration needed on Discord to create the bot, but no programming is required. This is forked from https://github.com/bchanudet/OctoPrint-Octorant.

Note, using this plug-in requires building and setting up your own discord bot.

Create the Discord Bot in Discord

See the following link for instructions on how to setup a Discord bot:

Tips

• The Channel ID is the ID of the TEXT channel within the Discord Server that the bot is communicating with, not the Discord Server.
• When following (https://github.com/Chikachi/DiscordIntegration/wiki/How-to-get-a-token-and-channel-ID-for-Discord), STOP after "Get the channel ID of the Discord text channel" section. Everything else is not needed on that page.
• OAuth2 permissions are not necessary.
• If you reinstall your Octoprint system, you only need the bot token and channel ID to get it back up and running.

API

There are currently 2 API's available for interacting with the bot. These can be used by sending a POST request to [octoprint_url]/api/plugin/discordremote, with JSON in the body of the request.

Send command

This API lets you send a command as if you typed it in discord. The response will be sent to discord. The JSON format is:

{
    "command": "executeCommand",
    "args": "COMMAND GOES HERE"
}

Send message

This API lets you send a message directly to discord. The JSON format is:

{
    "command": "sendMessage",
    "title": "TITLE GOES HERE",
    "description": "DESCRIPTION GOES HERE",
    "color": 0x123456,
    "image": "BASE64 ENCODED FILE DATA HERE",
    "imagename": "IMAGE NAME GOES HERE"
}

• All fields are optional, but at least a title, description or image should be provided.
• The color is an integer value here that corresponds to the color you want.
• The image is base64 bytes.
• The image name defaults to "snapshot.png" if not provided.

Commands

To get a list of available commands and arguments, type /help into the discord channel. The bot will return all available commands. Commands can also be sent via the web interface, by clicking the button in the top panel that looks like a game controller.

Configuration

The plugin can be configured in the configuration panel, under the "DiscordRemote" panel.

Discord Settings

• Bot Token: The token for a discord bot.
• Channel ID: The ID of a channel the bot will listen and post to. Ensure that this is locked down so that strangers cannot send commands to your printer, or whitelist users using the "Access Settings"

In order for you to be sure these settings work, every time you change one of them, a test message will be sent to the corresponding Discord Channel. If you don't receive it, something is most likely wrong!

Access Settings

The access settings allow specific commands to be limited to specific users.

• In the commands section, put a comma-separated list of commands.
• In the users section, put a comma-separated list of user IDs.
• A '*' in either section can be used to match all commands/users.

If the current command and user combination matches any of the rules, it will be executed. If additional rules are required, manually editing the config will be required.

Message Settings

Here you can customize every message handled by DiscordRemote.

• Toggle the message : by unchecking the checkbox in front of the message title, you can disable the message. It won't be sent to Discord.
• Message : you can change the default content here. See the section Message format for more information.
• Include snapshot : if you have a snapshot URL defined in the Octoprint settings, you can choose to upload a snapshot with the message to Discord.
• Notify every XX% : specific to the printing progress message, this settings allows you to change the frequency of the notification :
  • 10% means you'll receive a message at 10%, 20%, 30%, 40% ... 80%, 90% of the printing process.
  • 5% means you'll receive a message at 5%, 10%, 15%, 20% ... 80%, 85%, 90%, 95% of the printing process.
  • etc...
• Timeout : for small prints, prevents discord spam by only sending progress messages after the timeout has passed since the previous message.
