iOSMB-Router

Automated message routing and auto-reply service for iOSMB (iOS Message Bridge). Create rules to forward messages from specific senders to multiple recipients or automatically reply to incoming messages.

Features

• Message Forwarding - Redirect messages from specific senders to multiple recipients
• Auto-Reply - Automatically respond to messages based on sender
• YAML Configuration - Easy-to-read and modify rules
• Real-time Processing - Processes messages as they arrive via WebSocket
• Docker Support - Easy deployment with Docker and Docker Compose
• Environment Variables - Configure server connection without modifying code

Quick Start

Using Docker Compose (Recommended)

1. Copy the environment file:

   cd iOSMB-Router
   cp .env.example .env

2. Edit .env with your iOSMB server details:

   IOSMB_SERVER_IP=192.168.1.100
   IOSMB_SERVER_PORT=8180
   IOSMB_SERVER_PASSWORD=your-server-password
   IOSMB_SERVER_SSL=false

3. Create your rules file:

   cp rules.example.yaml rules.yaml
   # Edit rules.yaml with your custom rules

4. Start the service:

   docker-compose up -d

5. View logs:

   docker-compose logs -f

Using Go Directly

1. Install dependencies:

   go mod download

2. Create configuration:

   cp .env.example .env
   cp rules.example.yaml rules.yaml
   # Edit both files

3. Run the service:

   source .env
   go run main.go

Rules Configuration

Rules are defined in rules.yaml using a simple YAML format:

Redirect Rule Example

Forward all messages from Netflix to multiple phone numbers:

rules:
  - name: "Forward Netflix notifications"
    type: redirect
    from_sender: "Netflix"
    to_receivers:
      - "+33722335544"
      - "+33755442211"
    enabled: true

Auto-Reply Rule Example

Automatically reply to a specific sender:

rules:
  - name: "Auto reply to friend"
    type: auto_reply
    from_sender: "+33233556699"
    reply_text: "I will answer you shortly"
    enabled: true

Auto-Reply After Silence Rule Example

Automatically reply only if there hasn't been a conversation for a specified time:

rules:
  - name: "Auto reply after 1 hour of silence"
    type: auto_reply_after_silence
    from_sender: "+33611223344"
    reply_text: "I will reply you soon"
    silence_duration_secs: 3600  # 1 hour (3600s), 2h (7200s), 30min (1800s)
    enabled: true

Note: The silence tracking tracks BOTH incoming and outgoing messages in-memory. When either you or the sender messages, it updates the timer. After a restart, tracking begins fresh - the first message from each sender starts the timer, and the second message will trigger the auto-reply if the silence duration has elapsed.

Scheduled Message Rule Example

Send messages automatically at specific times using cron syntax:

rules:
  # Every day at 9:00 AM
  - name: "Daily morning reminder"
    type: scheduled_message
    schedule: "0 0 9 * * *"
    message_text: "Good morning! Don't forget your daily tasks."
    to_receivers:
      - "+33611223344"
      - "+33722335544"
    enabled: true

  # Every Saturday at 3:30 PM
  - name: "Weekly Saturday message"
    type: scheduled_message
    schedule: "0 30 15 * * 6"
    message_text: "Happy Saturday!"
    to_receivers:
      - "+33611223344"
    enabled: true

  # Every hour at 55 minutes
  - name: "Hourly reminder"
    type: scheduled_message
    schedule: "0 55 * * * *"
    message_text: "Hourly check-in"
    to_receivers:
      - "+33611223344"
    enabled: true

Cron Format: second minute hour day month weekday

• * = any value
• */15 = every 15 units
• 0 0 9 * * * = Every day at 9:00:00 AM
• 0 30 15 * * 6 = Every Saturday at 3:30:00 PM
• 0 0 */2 * * * = Every 2 hours
• 0 0 8-17 * * 1-5 = Every hour from 8 AM to 5 PM on weekdays

Environment Variables

Variable	Default	Description
IOSMB_SERVER_IP	192.168.1.100	iOSMB server IP address
IOSMB_SERVER_PORT	8180	iOSMB server port
IOSMB_SERVER_PASSWORD	-	iOSMB server password

How It Works

1. Connects to your iOSMB server via WebSocket (same connection as the web client)
2. Authenticates using the server password
3. Listens for incoming messages in real-time
4. Matches messages against your defined rules
5. Executes actions (forward or auto-reply) when rules match

Building from Source

# Clone the repository
cd iOSMB-Router

# Build binary
go build -o iosmb-router .

# Run
./iosmb-router

Troubleshooting

Connection Issues

• Verify IOSMB_SERVER_IP and IOSMB_SERVER_PORT are correct
• Ensure the iOSMB server is running and accessible
• Check if SSL is required (IOSMB_SERVER_SSL=true)

Rules Not Matching

• The from_sender field uses case-insensitive substring matching
• Example: "Netflix" will match "netflix", "NETFLIX", "Netflix Support"
• Check logs to see incoming message details

Messages Not Sending

• Verify phone numbers include country code (e.g., +33...)
• Check that the iOSMB server allows message sending
• View logs for error messages
