Smart Home with Wio Link/Wio Node and Telegram App

The Internet of Things (IoT) is a complex concept made up of many computers and many communication paths. Some IoT devices are connected to the Internet and some are not. Some IoT devices form swarms that communicate among themselves. Some are designed for a single purpose, while some are more general purpose computers.

In this tutorial we will learn, How control Wio Link/Wio Node via Telegram bot API. This is just a demo and all parts of it can be changed.

The tutorial consisted of two parts :

1. Preparation Wio Link/Wio Node

2. Preparation Telegram bot

Part 1 (Preparation Wio Link/Wio Node)

Wio Link/Wio Node is designed to simplify your IoT development. It is an ESP8266 based open-source Wi-Fi development board to create IoT applications by virtualizing plug-n-play modules to RESTful APIs with mobile APPs.

Please Install Android/iOS App and Follow the steps in the following link:

In this tutorial can be used from one or even several Wio Link/Wio Node. The important thing is that Wio Tokens are carefully remembered. (This token will be used in the second part.)

Part 2 (Preparation Telegram bot)

Introduction Telegram bot

Bots are third-party applications that run inside Telegram. Users can interact with bots by sending them messages, commands.

How do bots work?

At the core, Telegram Bots are special accounts that do not require an additional phone number to set up. Users can interact with bots and send messages and commands to bots by opening a chat with them or by adding them to groups or send requests directly from the input field by typing the bot's @username and a query.

Messages, commands and requests sent by users are passed to the software running on your servers.

How do I create a bot?
