A smart home automation system with device self-discovery

The underlying protocol is called UPnP (Universal Plug-n-Play). It uses a protocol called SSDP(Simple Service Discovery Protocol) to discover devices in the local network and retreive their IP address and their services description.

This project aims to demo that through a simple implementation of SSDP. The Node.js server uses SSDP to discover devices on the local network, and uses Socket.io to transmit to the client in real-time. Clients can not only connect and use devices, they can even associate with their account

• NodeMCU ESP8266 (To emulate a smart LED Bulb)
• LEDs for switching one (prefferably coloured ones)
• 330 ohms resistor X 4
• Breadboard
• Jumper Wires

• After setting up the circuit and flashing the code, boot up the NodeMCU.
• It starts in station mode, creating a WiFi hotspot with a name starting with ESP
• Connect to the hostpot, go to 192.168.4.1.
• Add in your WiFi credentials, and then after the MCU reboots, you are ready to use it.

• Node.js 14.15.4 LTS
• Yarn 1.22.10

• To install dependencies:

yarn install

• Copy the .env.sample and rename it to .env.
• Edit the .env file to fill in your server details such as port number, JWT secret and MongoDB URI. To access the frontend, set NODE_ENV to "production".
• To start the server:

yarn start

• Navigate to http://localhost:<PORT> to access your dashboard.
