Smdn.TPSmartHomeDevices.Kasa 2.0.0

Smdn.TPSmartHomeDevices.Kasa 2.0.0

Smdn.TPSmartHomeDevices.Kasa is a library that provides APIs for operating Kasa, the TP-Link smart home devices. This library performs operations by communicating directly with Kasa devices in the same network. Remote operation via the Internet is not supported.

This library also provides following features:

• Automatic connection management, including reconnection.
• Built-in/customizable error handling for typical errors and retries (like device busy, request timeout).
• Using MAC address and following IP address change in DHCP networks (requires Smdn.TPSmartHomeDevices.MacAddressEndPoint).
• async operation and cancellation.

Getting started

First, add package Smdn.TPSmartHomeDevices.Kasa to the project file.

dotnet add package Smdn.TPSmartHomeDevices.Kasa

To operate the Kasa device, write code like the following. Replace the Kasa device's IP address with yours.

using Smdn.TPSmartHomeDevices.Kasa;

// Creates device controller for Kasa KL130 multicolor light bulb.
using var bulb = new KL130(
  "192.0.2.1" // IP address currently associated to KL130
);

// Turns on the bulb, and set the color temperature and brightness.
await bulb.SetColorTemperatureAsync(colorTemperature: 5500, brightness: 80);

// Turns off the bulb
await bulb.TurnOffAsync();

More examples can be found on the GitHub repository, including examples of using other Kasa devices and their functionalities, and examples of using library features.
