Introduction

In this tutorial, you will learn how to wake your computer using your iOS or Android smartphone. We will cover the steps necessary to set up Wake On LAN (WoL) for Windows, macOS, or Linux systems. Additionally, we will integrate this functionality with Apple's HomeKit using HomeBridge, allowing you to control your computer via Siri. By the end of this guide, you'll be able to power on your computer remotely and enhance your smart home setup.

2. Type ipconfig /all and press Enter.
3. Locate the "Physical Address" of your network adapter.

On macOS

1. Open Terminal.
2. Type ifconfig and press Enter.
3. Find the line that starts with ether, which shows your MAC address.

On Linux

1. Run the command ifconfig in the terminal.
2. Look for the HWaddr or ether line to find your MAC address.

Step 4: Set Up Wake On LAN in the Fing App

1. Open the Fing app on your smartphone.
2. Tap on "Scan for devices" to identify devices on your network.
3. Locate your computer from the list and tap on it.
4. Select the option to add it as a favorite for easier access.
5. Ensure you note the MAC address for Wake On LAN.

Step 5: Integrate with HomeKit Using HomeBridge

To control your computer with Siri, you will need to set up HomeBridge.

Installation

1. Install Node.js on your computer (check the official website for instructions).
2. Open your terminal or command prompt and run:

   npm install -g homebridge
   

3. Install the HomeBridge Wake On LAN plugin:

   npm install -g homebridge-wol
   

Configuration

1. Create a configuration file config.json in the .homebridge directory.
2. Add the following configuration, replacing the placeholder values:

   {
     "platforms": [
       {
         "platform": "wol",
         "name": "Wake On LAN",
         "devices": [
           {
             "name": "Your Computer Name",
             "ip": "Your Computer IP",
             "mac": "Your Computer MAC"
           }
         ]
       }
     ]
   }
   

Conclusion

You have successfully set up Wake On LAN for your computer and integrated it with HomeKit using HomeBridge. Now you can wake your computer using your smartphone or with a simple Siri command. This setup enhances your smart home experience by allowing seamless control over your devices.
