BlueBubbles (iMessage)

Connect Hermes to Apple iMessage via BlueBubbles ↗ — a free, open-source macOS server that bridges iMessage to any device.

• A Mac (always on) running BlueBubbles Server ↗
• Apple ID signed into Messages.app on that Mac
• BlueBubbles Server v1.0.0+ (webhooks require this version)
• Network connectivity between Hermes and the BlueBubbles server

1. Install BlueBubbles Server

Download and install from bluebubbles.app ↗. Complete the setup wizard — sign in with your Apple ID and configure a connection method (local network, Ngrok, Cloudflare, or Dynamic DNS).

2. Get your Server URL and Password

In BlueBubbles Server → Settings → API, note:

• Server URL (e.g., http://192.168.1.10:1234)
• Server Password

3. Configure Hermes

Run the setup wizard:

hermes gateway setup

Select BlueBubbles (iMessage) and enter your server URL and password.

Or set environment variables directly in ~/.hermes/.env:

BLUEBUBBLES_SERVER_URL=http://192.168.1.10:1234
BLUEBUBBLES_PASSWORD=your-server-password

Optional: Require mentions in group chats

By default, Hermes responds to every authorized BlueBubbles/iMessage DM or group message. To make group chats opt-in, enable mention gating:

platforms:
  bluebubbles:
    enabled: true
    extra:
      require_mention: true

With require_mention: true, DMs still work normally, but group-chat messages are ignored unless they match a mention pattern. If you do not configure custom patterns, Hermes uses conservative defaults for Hermes and @Hermes agent variants.

For a custom agent name, set regex patterns:

platforms:
  bluebubbles:
    extra:
      require_mention: true
      mention_patterns:
        - '(?<![\w@])@?amos\b[,:\-]?'

4. Authorize Users

Choose one approach:

DM Pairing (recommended): When someone messages your iMessage, Hermes automatically sends them a pairing code. Approve it with:

hermes pairing approve bluebubbles <CODE>

Use hermes pairing list to see pending codes and approved users.

Pre-authorize specific users (in ~/.hermes/.env):

BLUEBUBBLES_ALLOWED_USERS=user@icloud.com,+15551234567

Open access (in ~/.hermes/.env):

BLUEBUBBLES_ALLOW_ALL_USERS=true

5. Start the Gateway

hermes gateway run

Hermes will connect to your BlueBubbles server, register a webhook, and start listening for iMessage messages.

iMessage → Messages.app → BlueBubbles Server → Webhook → Hermes
Hermes → BlueBubbles REST API → Messages.app → iMessage

• Inbound: BlueBubbles sends webhook events to a local listener when new messages arrive. No polling — instant delivery.
• Outbound: Hermes sends messages via the BlueBubbles REST API.
• Media: Images, voice messages, videos, and documents are supported in both directions. Inbound attachments are downloaded and cached locally for the agent to process.

Auto-marking messages as read is controlled by the send_read_receipts key under platforms.bluebubbles.extra in ~/.hermes/config.yaml (default: true). There is no corresponding environment variable.

Text Messaging

Send and receive iMessages. Markdown is automatically stripped for clean plain-text delivery.

Rich Media

• Images: Photos appear natively in the iMessage conversation
• Voice messages: Audio files sent as iMessage voice messages
• Videos: Video attachments
• Documents: Files sent as iMessage attachments

Tapback Reactions

Love, like, dislike, laugh, emphasize, and question reactions. Requires the BlueBubbles Private API helper ↗.

Typing Indicators

Shows "typing..." in the iMessage conversation while the agent is processing. Requires Private API.

Read Receipts

Automatically marks messages as read after processing. Requires Private API.

Chat Addressing

You can address chats by email or phone number — Hermes resolves them to BlueBubbles chat GUIDs automatically. No need to use raw GUID format.

Some features require the BlueBubbles Private API helper ↗:

• Tapback reactions
• Typing indicators
• Read receipts
• Creating new chats by address

Without the Private API, basic text messaging and media still work.

"Cannot reach server"

• Verify the server URL is correct and the Mac is on
• Check that BlueBubbles Server is running
• Ensure network connectivity (firewall, port forwarding)

Messages not arriving

• Check that the webhook is registered in BlueBubbles Server → Settings → API → Webhooks
• Verify the webhook URL is reachable from the Mac
• Check hermes logs gateway for webhook errors (or hermes logs -f to follow in real-time)

"Private API helper not connected"

• Install the Private API helper: docs.bluebubbles.app ↗
• Basic messaging works without it — only reactions, typing, and read receipts require it
