Telegram Bot - Aanwezigheids Checker

A simple Telegram bot that responds to the /check command with a string of dots.

Setup

1. Install dependencies:

pip install -r requirements.txt

2. Get a Telegram bot token:

   • Open Telegram and search for @BotFather
   • Send /newbot and follow the instructions
   • Copy the bot token you receive

3. Set the bot token. You can use either method:

   Option A: Using a .env file (recommended)

   # Create a .env file in the project directory
   echo "TELEGRAM_BOT_TOKEN=your_token_here" > .env
   echo "WHITELISTED_USER_IDS=123456789,987654321" >> .env

   Option B: Using environment variable

   export TELEGRAM_BOT_TOKEN='your_token_here'
   export WHITELISTED_USER_IDS='123456789,987654321'

   Note: The WHITELISTED_USER_IDS is optional. If not set, all users can use the bot. If set, only the specified user IDs (comma-separated) will be able to use the bot. You can get a user's ID by having them send /start to the bot.

4. Run the bot:

python bot.py

Usage

Once the bot is running, send /check to any chat where the bot is present, and it will reply with a string of dots.
