In this Lab, you’ll learn how to provide access to sensor data by creating and deploying a Telegram bot, enabling seamless interaction and real-time data retrieval through a user-friendly messaging platform.

The basic Bot

The first Bot will be a simple example that returns a random number between 0 and 100.

Step 1:

The https://github.com/python-telegram-bot/python-telegram-bot package is necessary to program the Bot. You’ll have to install it using:

python3 -m pip install python-telegram-bot

Step 2:

To create your Bot, you need an Access Token. To generate an Access Token, you have to talk to the BotFather following a few simple steps as described here: https://core.telegram.org/bots/tutorial#obtain-your-bot-token

<aside> 🗣

You need a Telegram account and the Telegram app installed on your smartphone, or the web app at https://web.telegram.org/.

The “dialogue” will be something like this:

Store the token somewhere !!!

Step 3:

Below is the code (file: tel_1.py) that returns a random number. The program defines three asynchronous functions (async def), which allow the bot to handle multiple user interactions efficiently without blocking execution:

• start: Triggered by the /start command. It sends a welcome message to the user, confirming that the bot is active.
• getdata: Triggered by the /getdata command. It generates a random integer between 0 and 100 using Python’s built-in random module and sends it to the user.
• unknown: Handles any unrecognized text input that is not a valid command, guiding the user toward the available commands.

The use of async and await enables non-blocking communication with the Telegram servers. This means the bot can process multiple messages concurrently, improving responsiveness and scalability, especially when handling many users simultaneously.
