By Claire WhitakerWhen you add multiple smart home devices that rely on a wired Ethernet connection, you will likely need a network switch. The two main types—unmanaged and managed—serve different purposes. An unmanaged switch works right out of the box with no configuration, while a managed switch gives you tools to organize traffic, improve security, and monitor performance. This article explains what each type does, which features matter for a smart home, and how to decide which one fits your setup.
What a Network Switch Does
A network switch is a device that connects multiple wired devices to your local network. Unlike a router, which routes traffic between your home network and the internet, a switch simply forwards data between devices on the same network. In a smart home, you might use a switch to connect smart hubs, security camera recorders, media streamers, game consoles, or desktop computers that need a reliable wired connection.
Switches come in two broad categories: unmanaged and managed. The difference lies in how much control you have over the traffic flowing through them. A router typically includes a built-in switch with a few ports, but if you need more wired connections, you add a separate switch.
Unmanaged Switches: Plug-and-Play Simplicity
An unmanaged switch is the simplest type. You plug it into power, connect an Ethernet cable from your router to one of its ports, and then connect your devices to the remaining ports. The switch automatically learns where each device is and forwards data accordingly. There are no settings to adjust, no web interface to log into, and no passwords to manage.
For many smart homes, an unmanaged switch is all you need. It works silently in the background, adding extra ports without any configuration. It is also generally less expensive than a managed switch and requires no technical knowledge to install.
The trade-off is that you cannot control how traffic is prioritized, isolate devices from each other, or monitor bandwidth usage. If your network is simple and you only need more ports, an unmanaged switch is a straightforward solution.
Managed Switches: Control and Customization
A managed switch gives you administrative access to configure how the switch handles traffic. You can create separate virtual networks, prioritize certain types of data, and view detailed statistics about what is connected and how much bandwidth each device uses.
Managed switches are common in business and enterprise networks, but they are becoming more relevant in advanced smart homes where security, performance, and organization matter. They require some networking knowledge to set up, but many consumer-oriented managed switches offer a simplified web interface that makes basic tasks accessible.
Key Features of Managed Switches
The three features most relevant to a smart home are VLANs, QoS, and monitoring.
VLANs (Virtual Local Area Networks)
A VLAN lets you split a physical network into multiple logical networks. For example, you could put all your smart home devices on one VLAN and your computers and phones on another. This separation improves security because devices on one VLAN cannot directly communicate with devices on another VLAN unless you allow it through your router. In a smart home, this is useful for isolating potentially less secure IoT devices from your main devices that hold personal data.
If you want to create a separate IoT network, a managed switch with VLAN support gives you more flexibility than relying solely on your router’s guest network feature. You can read more about the differences in our article on guest network vs separate IoT network.
QoS (Quality of Service)
QoS allows you to prioritize certain types of traffic over others. For example, you could give video streams from a security camera recorder higher priority than file downloads from a computer. This helps ensure that important data gets through even when the network is busy. In a smart home, QoS can prevent a large software update from causing a video doorbell stream to stutter.
Monitoring and Troubleshooting
Managed switches often provide port statistics, traffic graphs, and logs. This information can help you identify which device is using the most bandwidth, spot unusual activity, or troubleshoot a connection problem. For instance, if a smart light hub keeps disconnecting, you can check the switch’s log to see if the port is dropping packets.
PoE: A Separate Consideration
Power over Ethernet (PoE) is a feature that allows the switch to deliver electrical power through the same Ethernet cable that carries data. This is useful for devices such as security cameras, video doorbells, wireless access points, and some smart home hubs that can be powered over Ethernet. We also found Alexa Devices vs Google Home: Which Ecosystem Fits Your Home? useful on this point.
PoE is not tied to whether a switch is managed or unmanaged. You can find both unmanaged PoE switches and managed PoE switches. If you plan to install devices that support PoE, you need a switch that provides PoE on the ports you will use. PoE switches are rated by the total power budget they can deliver, so check the power requirements of your devices and the switch’s specifications.
For a smart home with several PoE cameras, a PoE switch simplifies installation by eliminating the need for separate power adapters. If you only have one or two PoE devices, you might use a PoE injector instead of a PoE switch.

When an Unmanaged Switch Is the Right Choice
An unmanaged switch is the right choice for most smart homes that simply need more wired ports. If you have a router that already handles all your network settings, and you just want to connect a few devices like a smart hub, a media streamer, and a game console, an unmanaged switch will work without any fuss.
It is also a good option when you want to keep your network setup simple and do not need to isolate smart devices from each other. For example, if you only have a handful of smart lights and a thermostat that connect wirelessly, and you only need a wired connection for a security camera recorder, an unmanaged switch is sufficient.
If you are new to home networking and prefer a device that requires no configuration, an unmanaged switch is the way to go. It is also a cost-effective way to expand your network without adding complexity.
When a Managed Switch Is the Right Choice
A managed switch becomes valuable when your smart home grows and you need more control over network traffic and security. Consider a managed switch if you have a large number of IoT devices and you want to isolate them from your main network to improve security. VLANs let you create a separate network for smart devices without needing multiple physical routers.
If you experience performance issues such as video streams buffering while other devices are downloading large files, QoS on a managed switch can help prioritize the video traffic. This is especially useful if you have multiple security cameras streaming to a recorder or a network video recorder.
Managed switches are also helpful if you want to monitor your network to troubleshoot problems or track bandwidth usage. For instance, if a smart device goes offline after a power outage, a managed switch’s logs can help you identify whether the device lost connection or the switch port failed. See our guide on smart devices offline after a power outage for more troubleshooting steps.
If you plan to set up a separate IoT network using VLANs, a managed switch is essential. You can learn more about this approach in our article on guest network vs separate IoT network.
Upkeep and Long-Term Ownership
Unmanaged switches require almost no upkeep. Once installed, they run indefinitely as long as they have power and the ports are not damaged. There are no firmware updates to worry about, though some models may receive occasional updates if they are part of a larger system.
Managed switches require more attention. You should check for firmware updates periodically to patch security vulnerabilities and fix bugs. The configuration you set up (VLANs, QoS rules) will persist, but if you change your router or network layout, you may need to adjust the switch settings. Some managed switches offer a web interface that you can access from any browser, making it easy to make changes.
Both types of switches are generally reliable and can last for many years. The main difference in long-term ownership is the level of involvement you want. If you prefer a set-it-and-forget-it approach, an unmanaged switch is ideal. If you enjoy tweaking settings and want full control, a managed switch gives you that flexibility.
When choosing between the two, also consider your future plans. If you might add PoE devices later, look for a PoE switch (managed or unmanaged) that meets your power needs. If you think you will want VLANs or QoS down the road, it may be easier to buy a managed switch now rather than replace an unmanaged one later.
FAQ
Can I use an unmanaged switch with a managed switch on the same network?
Yes. You can connect an unmanaged switch to a managed switch, or to a router, and it will work as a simple port expander. The unmanaged switch will not support VLANs or QoS, but it will pass traffic normally. For VLANs to work across switches, all switches in the path need to be managed and configured correctly.
Do I need a managed switch for a smart home with only a few devices?
Not usually. If you have fewer than ten wired devices and you do not need to isolate them or prioritize traffic, an unmanaged switch is sufficient. A managed switch becomes useful when you have many devices, security concerns, or performance demands.
What is the difference between a managed switch and a smart switch?
In the networking world, a “smart switch” is often a term for a basic managed switch that offers a limited set of features (like VLANs and QoS) through a simple web interface, but without the full command-line control of an enterprise managed switch. For a smart home, a smart switch can be a good middle ground—it gives you some control without the complexity of a fully managed switch.
Can a managed switch improve the performance of my smart home?
It can, if you use QoS to prioritize critical traffic such as video streams from security cameras or voice commands to smart speakers. Without QoS, a managed switch does not inherently make your network faster; it only gives you the tools to manage bandwidth. If your network is already fast enough, an unmanaged switch will perform the same.
Choosing between a managed and unmanaged network switch comes down to your need for control, security, and monitoring. For a simple smart home that just needs more ports, an unmanaged switch is a reliable, low-cost solution. As your smart home grows and you want to isolate devices, prioritize traffic, or troubleshoot issues, a managed switch provides the tools to do that. Consider your current setup and future plans, and you can pick the switch that fits your home network.
