OmegaBaSMS

Forward WhatsApp group messages to SMS — batched and free.

How it works

Monitors specified WhatsApp groups via WhatsApp Web
Queues incoming messages for a configurable interval (default 30s)
Flushes all queued messages as a single SMS via TextBee (uses your Android phone's mobile plan)
If the WhatsApp session expires, sends the QR code to Telegram for easy re-auth

Requirements

Node.js 18+
Android phone with mobile plan (for TextBee)
Telegram account (for QR re-auth notifications)

Setup

1. TextBee (SMS Gateway)

Create a free account at textbee.dev
Install the TextBee app on your Android phone
In the dashboard, register your device (scan QR with the app)
Copy your Device ID and API key

2. Telegram Bot (QR re-auth)

Open Telegram, search for @BotFather, send /newbot
Choose a name and username, get the bot token
Message your bot once, then visit: https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates
Copy your chat ID from the response

3. Configuration

cp .env.example .env
