A broker is a server which allows clients to send short messages to the broker and receive messages if they are subscribed to certain topic. These devices act as the client who communicates to the server known as broker. MQTT is a TCP/IP based publish and subscribe protocol which is designed for lightweight machine to machine interactions with IOT devices. MQTT stands for Message Query Telemetry Transport. You just need to send a text message to a chatbot which can control lights in your home from any part of the world. Like here we will use Facebook to control the devices in our home remotely. These features of Facebook can be really helpful in building any IoT based project. In this project we will look how to make Facebook home Automation using Facebook messenger.
