How to Monitor Network Traffic in Your Smart Home
As I sat on my couch, casually asking my smart assistant to dim the lights and play some relaxing music, I realised something I hadn't considered deeply before: all of these interactions were happening over my home network. Every command, every automated device, every sensor — all were using my internet connection, exchanging data back and forth. Suddenly, it hit me how essential it is to understand and monitor the network traffic in a smart home, especially if I want to keep things secure and running smoothly.
In a home filled with smart devices, it's crucial to know what’s going on behind the scenes. So, today, I want to walk you through how you can monitor the network traffic in your smart home, why it’s important, and how to ensure your devices aren’t becoming a gateway for security vulnerabilities.

Why Monitoring Network Traffic in a Smart Home Matters
Before diving into how to monitor network traffic, it’s important to understand why it matters in the first place. Every smart device in your home – whether it’s a thermostat, camera, or smart speaker – is continuously sending and receiving data. This data might include sensitive information, such as video feeds from security cameras or even information about your daily habits.
Monitoring your network traffic allows you to:
- Detect Unusual Activity: If a device is sending an unexpected amount of data or communicating with strange servers, it could be compromised. This is one of the first signs that something might be wrong.
- Manage Bandwidth Usage: Ever noticed that your smart TV struggles to stream a movie when someone else is downloading a large file? Monitoring traffic helps you pinpoint which devices are hogging bandwidth so you can manage your network more efficiently.
- Improve Security: You can track and block suspicious connections, ensuring that no one is gaining unauthorised access to your network or your smart devices.
Once I started monitoring my network, I quickly realised how many devices were connected and just how much data they were using. Let’s just say, it was an eye-opener!
Tools for Monitoring Network Traffic
So, how do you go about monitoring your smart home network? Thankfully, you don’t need to be a tech genius or invest in expensive equipment to get started. Here are some tools that have helped me keep an eye on things.
1. Router-Based Monitoring
The simplest way to monitor your network traffic is through your router. Most modern routers come with built-in traffic monitoring tools. Depending on the brand and model, you might be able to see a detailed breakdown of how much data each connected device is using. Some even allow you to set up alerts for unusual activity.
For example, when I logged into my router’s dashboard, I could immediately see which devices were active and how much bandwidth they were consuming. I was even able to block certain devices from connecting to the internet during specific times – handy for limiting my smart speaker’s traffic when I wasn’t using it.
2. Third-Party Network Monitoring Software
If your router doesn’t offer in-depth traffic analysis, third-party software can fill in the gaps. Tools like Wireshark and GlassWire provide real-time traffic monitoring and analysis, allowing you to see which devices are communicating with which servers and how much data they’re transmitting.
I’ve used GlassWire in my own home and was surprised to see how much traffic my smart cameras were sending out. The software alerted me to a spike in data usage, which prompted me to review the footage and make sure everything was normal. It’s comforting to have that level of visibility.
3. Mobile Apps
There are also mobile apps that let you monitor your network traffic on the go. Apps like Fing or Netgear Nighthawk provide real-time updates on all devices connected to your network, and some even offer the ability to block devices remotely.
I’ve found that using an app like Fing is especially helpful when I’m away from home. It sends me notifications whenever a new device connects to my network, which helps me keep track of everything – even when I’m not there.
Identifying Potential Network Issues
Monitoring your network traffic can help you identify potential issues before they become significant problems. Here are some things to watch for:
1. Unusually High Traffic
If you notice that one of your smart devices is consuming more bandwidth than usual, it could be a sign that something is wrong. I once noticed that my smart thermostat was sending out an abnormal amount of data, and after investigating, I realised it was due to a software bug that needed updating. Keep an eye on traffic spikes and investigate any unusual activity.
2. Unauthorised Devices
If you see a device on your network that you don’t recognise, it could be an intruder. Once, I noticed an unfamiliar device connected to my network, and it turned out to be a neighbour accidentally trying to use my Wi-Fi. While this wasn’t a malicious attack, it reminded me how important it is to keep an eye on who’s connected.
3. Slow Internet Speeds
If your internet seems slower than usual, it could be due to one or more devices using up too much bandwidth. By monitoring your network, you can identify the culprit and adjust usage or prioritise specific devices. I often adjust my smart TV’s settings to ensure it doesn’t slow down my other devices during streaming sessions.
Securing Your Smart Home Network
Monitoring your network traffic is only one part of securing your smart home. To truly protect your devices, you need to take a few additional steps:
1. Use Strong Passwords
I can’t stress this enough – always use strong, unique passwords for both your router and your smart devices. Avoid using the default passwords that come with your devices, as these are often easy to guess or find online.
2. Enable Two-Factor Authentication
Whenever possible, enable two-factor authentication (2FA) on your smart home devices. This adds an extra layer of security, ensuring that even if someone gets your password, they won’t be able to access your devices without the second factor of verification.
3. Update Device Firmware Regularly
Smart home devices often receive firmware updates that fix security vulnerabilities. Make sure to check for updates regularly and install them as soon as they’re available. I’ve had instances where skipping an update left my devices vulnerable to potential exploits, and it’s not a mistake I plan on making again.

Using a VPN for Extra Security
One additional step you can take to protect your smart home network is to use a Virtual Private Network (VPN). A VPN encrypts your internet traffic, making it much harder for hackers to intercept or tamper with your data. This can be especially useful if you’re accessing your smart home remotely from a public Wi-Fi network.
In my experience, setting up a VPN on my router was a bit of a technical challenge, but the added security was worth it. Now, whenever I access my home network from a café or hotel, I know my connection is secure and private.
Balancing Security and Convenience
One of the trade-offs with smart homes is balancing convenience with security. It’s tempting to focus solely on ease of use, but I’ve learned that a few extra steps can go a long way in protecting my devices and data. By monitoring my network traffic and following best practices for security, I’ve been able to enjoy the convenience of my smart home without compromising on safety.
