Yeelight TypeScript API Wrapper

Author: Gurel Ben Shabat (https://github.com/gurelbs)

This package provides a robust TypeScript library for controlling Yeelight smart devices over your local network. It simplifies the process of device discovery and command transmission, leveraging Node.js and TypeScript for a type-safe, event-driven architecture.

Features

• Device Discovery: Automatically locate Yeelight devices on your local network using SSDP.
• Control Commands: Send commands to control power, brightness, color, and more.
• Type Safety: Built with TypeScript for enhanced code reliability and maintainability.
• Event-Driven: Utilizes Node.js's EventEmitter for real-time device interaction.
• Easy Integration: Designed for easy integration into any Node.js or TypeScript project.

Installation

Install the package via npm:

npm install yeelight-ts

Usage

Here's how to get started with the Yeelight TypeScript API Wrapper:

1. Project Setup:

Create a new project directory and initialize a Node.js project:

mkdir yeelight
cd yeelight
npm init -y

2. Install Dependencies:

Install the yeelight-ts library and a development server like nodemon (optional, but recommended for automatic code reloading):

npm install yeelight-ts
npm install -g nodemon

3. Create an Entry Point:

Create a file named index.ts and add the following code:

import { Yeelight } from "yeelight-ts";

const yeelight = new Yeelight();
const IP = "192.168.x.x"; // Change this to your Yeelight's IP address

yeelight.setBrightness(IP, 50); // Example: Set brightness (1-100)

// Other control commands (uncomment to use):
// yeelight.setPower(IP, 'on'); // Turn on the light
// yeelight.setColorTemperature(IP, 6500); // Set cooler white
// yeelight.setRGB(IP, 0xFF0000);  // Set red color
// yeelight.setHSV(IP, 180, 100);  // Set purple color
// yeelight.setName(IP, 'Living Room Lamp'); // Set device name

4. Run the Application:

Start the application using nodemon for automatic code reloading during development:

nodemon index.ts

API Documentation

The Yeelight class provides the following methods:

• sendDiscovery(): Sends a discovery message to find Yeelight devices on the network.
• handleDiscoveryResponse(callback): Handles the discovery response from a Yeelight device and calls the provided callback function with the device information. (Refer to the source code for event-driven usage)
• sendCommand(ip, method, params): Sends a command to a Yeelight device with the specified IP address, method, and parameters. Returns a promise that resolves to the command result.
• setPower(ip, powerState, effect, duration): Sets the power state of a Yeelight device.
• setBrightness(ip, brightness): Sets the brightness of a Yeelight device.
• setColorTemperature(ip, temperature): Sets the color temperature of a Yeelight device.
• setRGB(ip, rgb): Sets the RGB color of a Yeelight device.
• setHSV(ip, hue, sat): Sets the HSV color of a Yeelight device.
• setName(ip, name): Sets the name of a Yeelight device.
• isInRange(value): Checks if a value is within the valid range (1-100).

Note: This is a basic overview. Refer to the actual source code for detailed descriptions and parameter types.
