Xiaomi Gateway 3 open telnet command – In this article, we will show you how to enable telnet xiaomi gateway 3.

Are you looking to unlock more advanced features on your Xiaomi Gateway 3? Enabling Telnet access can open up a world of possibilities for tinkering and configuring your gateway beyond what the standard Mi Home app provides.

What is Telnet and Why Enable It on Xiaomi Gateway 3?

Telnet is a network protocol that allows you to connect to devices over a command-line interface (CLI). By enabling Telnet on your Xiaomi Gateway 3, you gain:

1. Deeper Configuration: Access advanced settings that are not normally visible in the Mi Home app.
2. Customization: Integrate your Xiaomi Gateway 3 with other smart home solutions (like Home Assistant or Zigbee2MQTT) and tailor the firmware behavior to your preferences.
3. Greater Control: Debug and troubleshoot network or device issues more thoroughly.

While Telnet is an older protocol with fewer security features than SSH, for local use it can be a handy tool. That said, always be mindful of potential security risks. If you’re comfortable with enabling Telnet and understand the possible implications, let’s move forward!

Things you will need to Enable Telnet Xiaomi Gateway 3

Before you start, make sure you have the following:

1. Xiaomi Gateway 3 (model: ZNDMWG03LM) – This guide focuses specifically on this version of the Xiaomi Gateway.
2. A Stable Wi-Fi Network – Ensure your gateway is connected and functioning properly on your home network.
3. Computer with Telnet Client – Windows, macOS, or Linux will work. On some systems (like Windows), you may need to enable the Telnet client in your system’s settings.
4. Mi Home App (Optional) – Sometimes you need the Mi Home app for initial device setup or to ensure the firmware is updated.

Important Note: Enabling Telnet may void your device warranty. Proceed at your own risk and carefully follow the instructions. If you’re uncomfortable with this process, you may want to seek additional guidance from the community or reconsider if you truly need Telnet access.

How to Enable Telnet Xiaomi Gateway 3

In this tutorial, we’re referencing widely used community tools and scripts that make the process smoother. Let’s break it down.

Step 1: Check the Current Firmware Version

1. Open the Mi Home app on your smartphone.
2. Select your Xiaomi Gateway 3 from the list of devices.
3. Go to the Device Settings and check the Firmware Version.

Different firmware versions may require slightly different methods. However, most modern versions support the process we’ll cover. If a specific method doesn’t work, you might consider downgrading or upgrading firmware (though that can be an advanced step).

Step 2: Download the Required Tools or Scripts

Several community-driven GitHub projects allow you to enable Telnet on the Xiaomi Gateway 3. One of the popular repositories is maintained by AlexxIT. Search online for “XiaomiGateway3 AlexxIT GitHub” to find it.

1. Download the scripts (often in a .zip or .tar.gz format).
2. Extract the files to a folder on your computer where it’s easy to locate them.

Tip: Always scan downloaded files with an antivirus tool, just to be extra sure you’re getting clean code.

Step 3: Connect Your Gateway to the Debug Mode (If Required)

Some scripts or methods require you to enable debug mode within your Gateway. This can vary by firmware version. Typically, you’ll use a special network trick or the Mi Home app to trigger debug mode.

1. Follow the instructions in the readme file from the repository you downloaded.
2. Wait for any LED indications (if the script mentions them).
3. Confirm debug mode is active (the script or process you run will often display a success message).

Step 4: Run the Telnet Enable Script

Once your Xiaomi Gateway 3 is in debug or developer mode, you can run the Telnet enabling script:

1. Open a Command Prompt or Terminal on your computer.
2. Navigate to the folder where you extracted the Telnet enabling script.
3. If the script is a Python tool (for example), you might use python enable_telnet.py or a similar command.
4. The script should interact with your Gateway over your local network. When asked, enter the IP address of your Gateway 3 (you can find this in your router’s client list or in the Mi Home app under device settings).
5. Wait for the script to finish. You should see a confirmation message indicating Telnet is enabled.

Step 5: Verify Telnet Access

After the script completes, it’s time to verify whether Telnet is up and running:

1. Open a Terminal/Command Prompt on your computer.
2. Type:
   bash

   CopyEdit

   telnet 192.168.x.x


   Replace 192.168.x.x with the actual IP address of your Gateway.

3. If Telnet is successfully enabled, you’ll see a prompt asking for your login credentials (often root for older methods, or specified in the script’s documentation).
4. Enter your username/password if prompted. You should now have Telnet access to your Xiaomi Gateway 3!

Heads-Up: Some firmware versions might automatically lock you out after a reboot, requiring you to run the enabling script again. It’s always good practice to keep the script handy if that’s the case.

Troubleshooting Common Issues

Connection Timed Out

If you run into a “Connection timed out” error:

• Check Your Firewall Settings: Ensure your computer’s firewall or antivirus software isn’t blocking Telnet traffic.
• Verify the IP Address: Double-check the Gateway’s IP address, as it might have changed.

Telnet Prompt Rejects Credentials

• Confirm the Default Credentials: Some scripts use “admin,” “root,” or custom usernames/passwords. Make sure you’re using the correct ones outlined in the script.
• Firmware Limitations: Certain firmware versions restrict Telnet or user logins. You may need a different approach or a firmware downgrade.

Gateway Not Responding After Script

• Power Cycle Your Gateway: Unplug your Xiaomi Gateway 3, wait 10 seconds, and plug it back in. After it boots up, try the script again.
• Reset and Re-Add to Mi Home: In rare cases, you might need to reset the device to factory settings and rebind it in the Mi Home app before attempting to enable Telnet again.

What to Do After Enabling Telnet

Now that you have Telnet access, here are a few cool things to explore:

1. Integrate with Home Assistant: Many users prefer controlling all their smart devices under one dashboard. With Telnet access, you can follow guides to install or enable custom integrations.
2. Zigbee2MQTT: If you have Zigbee sensors, you can potentially flash or configure your Xiaomi Gateway 3 to work with the Zigbee2MQTT project, giving you more flexibility and device compatibility.
3. Backup & Restore Configurations: Telnet allows you to make backups of your config files, giving you peace of mind if something goes wrong.

Security Best Practices

Remember, Telnet is not encrypted, so your login credentials and commands travel in plain text. Here are some best practices:

• Use Telnet Only on Local Network: Avoid enabling remote internet access to Telnet.
• Change Default Credentials (If Possible): If your script or firmware version allows, switch to a stronger password.
• Disable Telnet When Not in Use: If you only need it temporarily, disable it after you’re done to reduce security risks.

Conclusion

Enabling Telnet on your Xiaomi Gateway 3 can significantly expand your smart home’s capabilities. From integrating advanced services like Home Assistant to fine-tuning system settings that aren’t normally available, Telnet opens the door to a more customizable experience.

However, it’s crucial to understand that you’re stepping into more technical territory, and there may be risks involved, including voiding warranties or exposing your device to vulnerabilities if not secured properly. Always proceed carefully and double-check the latest community-driven documentation for your firmware version.

If you’re ready to take your Xiaomi Gateway 3 to the next level, enabling Telnet can be a game-changer. We hope this guide helps you confidently embark on your smart home journey. Feel free to share your experiences or ask questions in the comments below!
