Telegram Balance Monitoring Bot

A robust asynchronous Telegram bot designed to monitor financial balances across various API services (Zadarma, DIDWW, Make) and manual subscription services (Wazzup, Streamtele, Callii).

The bot runs background scheduled tasks to check for low balances, calculates credit "runway" (burn rate), and notifies a specific administrative chat.

Features

  • API Integration:
    • Zadarma & DIDWW: Real-time balance checking.
    • Make (Integromat): Monitoring of "Operations" credits, automatic subscription date synchronization, and advanced "Burn Rate" calculation (predicts if credits will run out before the monthly reset).
  • Manual Tracking: State management for services without APIs (Wazzup, Callii) via FSM (Finite State Machine).
  • Recurring Payments: Automatic tracking of monthly subscriptions and daily usage costs.
  • Smart Alerts:
    • Low balance notifications.
    • Monthly payment reminders (1 day in advance).
    • "Friday Look-ahead": Checks if funds will last through the weekend.
    • Daily top-up reminders for high-consumption services.
  • Security: Restricted access to a specific target chat ID.

Tech Stack

  • Python 3.10+
  • aiogram 3.x: Asynchronous framework for Telegram Bot API.
  • SQLAlchemy + aiosqlite: Asynchronous ORM for SQLite database.
  • aiohttp: Asynchronous HTTP client for API requests.

Installation

  1. Clone the repository:

    git clone [https://github.com/derssen/telegram-balance-bot.git](https://github.com/derssen/telegram-balance-bot.git)
cd telegram-balance-bot

  2. Create a virtual environment:

    python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate

  3. Install dependencies:

    pip install -r requirements.txt

  4. Configuration: Create a .env file in the root directory:

    # Telegram
BOT_TOKEN=your_bot_token
TARGET_CHAT_ID=your_admin_chat_id

# Database
DATABASE_URL=sqlite+aiosqlite:///bot_db.sqlite3

# API Credentials (leave empty to disable service)
ZADARMA_KEY=
ZADARMA_SECRET=
DIDWW_KEY=

# Make (Integromat)
MAKE_API_KEY=your_token
MAKE_ORG_ID=your_org_id
MAKE_ZONE=eu1  # 'eu1' (default) or 'us1'

# Manual Services Costs
WAZZUP_DAILY_COST=400.0
CALLII_DAILY_COST=2.2

  5. Run the bot:

    python main.py

Project Structure

  • main.py: Entry point and scheduler loop.
  • config.py: Configuration and environment variable management.
  • db/: Database models and initialization.
  • handlers/: Telegram message and callback handlers.
  • services/: External API clients (Zadarma, DIDWW, Make).
