Unlike Amazon Alexa and Google Home, there are not many Apple HomeKit hubs available. Instead, you have the choice between the HomePod mini and Apple TV 4K, both of which work well as HomeKit hubs but have different purposes. If you're wondering which one would be a better HomeKit hub, here's what you need to know.

Prices
The HomePod mini costs $99 and comes in various colors (Space Gray, Blue, Yellow, White, and Orange). Apple TV 4K has two options: the Wi-Fi model with 64 GB of storage costs $129, and the Wi-Fi + Ethernet model with 128 GB of storage costs $149.

Features
Apple TV 4K is designed for easy access to streaming platforms like Netflix, Hulu, Apple TV+, YouTube TV, Apple Arcade, and Apple Music. It's a great addition to a home theater setup. On the other hand, the HomePod mini is a traditional smart speaker meant for tasks like playing music and controlling your smart home. It doesn't have streaming capabilities but can be paired with your home theater for audio.

Other Considerations
Apple TV 4K can be more responsive than the HomePod mini when connected to an Ethernet port, but most users won't notice much difference. It's worth noting that the Apple TV 4K needs to be connected to a display, while the HomePod mini can be placed anywhere in the home. Setting up the Apple TV 4K requires a screen, but the HomePod mini can be placed in various rooms. You also need to manually add Apple TV 4K to your Home app to use it as a hub, whereas the HomePod mini automatically becomes a hub.

Conclusion
Both the Apple TV 4K and HomePod mini work well as HomeKit hubs, but the HomePod mini is better suited for most households. It's affordable, easier to find a central location for, and works flawlessly no matter where it's placed. However, the Apple TV 4K offers a wired connection for faster response time and access to live video feeds, which may be appealing to power users. Consider your needs and preferences when making a decision.
