Smart Hub vs Gateway: What's the Difference?


When setting up a smart home, you might hear the terms "smart hub" and "gateway" used interchangeably. While both devices play a crucial role in connecting and controlling smart home devices, there are some key differences between them. Understanding these differences can help you choose the right device for your home automation needs.


Smart homes are becoming increasingly popular, with more and more homeowners turning to automation to enhance the comfort, convenience, and security of their living spaces. However, setting up a smart home can be daunting, with a wide range of devices and technologies to choose from.

Two devices that often come up in discussions of smart home technology are smart hubs and gateways. These devices act as a central point of control for smart home devices, allowing homeowners to manage their devices from a single app or interface. However, there are some important differences between the two devices that are worth considering before you make a purchase.

Smart Hub

A smart hub is a device that connects to your home network and communicates with various smart devices to control them. Smart hubs use a variety of wireless communication protocols, such as Wi-Fi, Bluetooth, Zigbee, Z-Wave, or Thread, to communicate with smart devices.

The main function of a smart hub is to act as a central control point for your smart devices. It allows you to control multiple devices using a single app, rather than having to use a separate app for each device. Smart hubs can also automate device control based on predefined rules, allowing for a more seamless and integrated experience.

Smart hubs usually come with a dedicated app that you can install on your smartphone or tablet. The app allows you to configure the smart hub and connected devices, create rules, and control the devices remotely.

One of the main advantages of a smart hub is that it allows you to integrate devices from different manufacturers into a single system. This is particularly useful if you have devices that use different wireless communication protocols. Smart hubs act as a translator, allowing devices to communicate with each other even if they use different protocols.

However, smart hubs can be more expensive than other types of smart home devices, and they may require additional setup and configuration. Additionally, some smart hubs may not support all wireless communication protocols, so it's important to check compatibility before purchasing a smart hub.


A gateway is a device that connects multiple devices with different protocols, allowing them to communicate with each other. It acts as a bridge between devices with different communication protocols, translating the information between them. A gateway typically uses a standard communication protocol, such as Wi-Fi or Ethernet, to connect to the internet and provide access to the cloud.

Gateway devices are commonly used in smart homes to connect devices that use different communication protocols, such as Zigbee or Z-wave, and integrate them into a single system. The gateway acts as the central hub for all connected devices, allowing users to control and manage them through a single interface, such as a mobile app or voice assistant.

One advantage of using a gateway is that it allows for the integration of a wider range of devices with different communication protocols, which provides more flexibility when building a smart home system. However, a gateway can be more complex to set up and may require more technical knowledge than a smart hub. It may also be more expensive, depending on the features and capabilities of the device.

Overall, the choice between a smart hub and a gateway will depend on the specific needs and requirements of the user. Those who require more flexibility and integration of devices with different protocols may find a gateway to be the better option, while those who want a simpler and more user-friendly experience may prefer a smart hub.

Differences between Smart Hub and Gateway

While both smart hubs and gateways serve as a central control point for smart home devices, there are some key differences between the two.

Connectivity: Smart hubs tend to have a broader range of connectivity options than gateways. They can connect to devices using Wi-Fi, Bluetooth, Z-Wave, Zigbee, and more, while gateways usually only support one or two protocols.

Processing Power: Smart hubs are typically more powerful than gateways, with more processing power and memory. This allows them to handle more devices and more complex automation rules.

User Interface: Smart hubs often have a user-friendly interface that can be accessed through a smartphone app or web interface. This makes it easy for users to control their smart home devices, set up automation rules, and monitor their home from anywhere.

Price: Smart hubs can be more expensive than gateways, as they offer more advanced features and broader compatibility. However, there are affordable options available, and many smart hubs offer a range of features that make them worth the investment.

Compatibility: One of the most important factors to consider when choosing between a smart hub and a gateway is compatibility. Make sure to check which protocols and devices are supported by each device before making a purchase. Some devices may only work with one or the other, while others may be compatible with both.

By understanding the differences between smart hubs and gateways, you can choose the right device for your smart home setup and enjoy the convenience and automation that these devices offer.

Choosing the Right Device for Your Smart Home

When it comes to choosing between a smart hub and a gateway, there are several factors to consider:

Compatibility with existing devices and systems

The first thing to consider is the compatibility of the device with your existing smart home devices and systems. Make sure to choose a device that can communicate with all your devices and systems to avoid any compatibility issues.

Budget and cost considerations

Another important factor to consider is your budget and the cost of the device. Smart hubs and gateways come in a wide range of prices, so it's important to choose a device that fits within your budget.

It's also important to factor in any ongoing costs, such as subscription fees or additional equipment needed to fully utilize the device.

By considering these factors, you can make an informed decision and choose the right device for your smart home setup.


It's important to understand the differences between a smart hub and a gateway when choosing the right device for your smart home. A smart hub acts as a central command center, allowing you to control all of your smart devices from one app, while a gateway connects your smart devices to the internet and enables communication between them. By understanding the differences between these devices and carefully uating your options, you can make an informed decision and build a smart home that works for you.
