Smart home hubs used to be essential for connecting devices. Today, many devices connect directly to Wi-Fi or work through smart speakers, so you may not need a dedicated hub. But hubs still offer benefits for reliability, local control and advanced automation.
This guide explains what hubs do, when you might need one and which options are popular. Product capabilities change, so check current details.
What Is a Smart Home Hub?
A smart home hub is a device that connects and coordinates smart home devices, often across different wireless protocols. Hubs can:
- Translate protocols like Zigbee, Z-Wave and Thread
- Run automations locally without relying on the cloud
- Unify devices from different brands
- Reduce Wi-Fi congestion by moving devices to separate networks
Smart Home Protocols
Wi-Fi
Many devices connect directly to your router. No hub is needed, but many Wi-Fi devices can strain some routers.
Zigbee
A low-power mesh protocol used by brands like Philips Hue, Aqara and IKEA. Requires a Zigbee hub or bridge.
Z-Wave
A low-power mesh protocol that operates on frequencies separate from Wi-Fi, commonly used in locks and sensors. Requires a Z-Wave hub.
Thread
A low-power mesh protocol used with Matter. Requires a Thread border router.
Matter
A standard that runs over Wi-Fi, Thread and Ethernet, designed for cross-platform compatibility. Requires a Matter controller. See Matter explained.
Do You Need a Hub?
You might not need a dedicated hub if:
- You use mostly Wi-Fi or Matter-over-Wi-Fi devices
- Your smart speaker or display already includes Zigbee or Thread support
- You only have a few devices
You might want a hub if:
- You use Zigbee or Z-Wave devices
- You want local automations that run without the internet
- You have many devices and want more reliability
- You want advanced automation and customization
Hubs Built Into Other Devices
Many devices act as hubs:
- Some Amazon Echo models include Zigbee hubs or Thread border routers.
- Some Google Nest devices act as Thread border routers and Matter controllers.
- Apple TV and HomePod serve as home hubs for Apple Home and can be Thread border routers.
- Some routers include smart home features.
Check specific models. See Alexa vs. Google Home.
Popular Dedicated Hubs
Samsung SmartThings
SmartThings offers hubs and integrates with many devices. Some Samsung TVs and appliances can act as SmartThings hubs.
Hubitat Elevation
Hubitat focuses on local processing and supports Zigbee and Z-Wave. Popular with users who want automation without cloud reliance.
Home Assistant
Home Assistant is open-source software that runs on devices like a Raspberry Pi or the company’s own hardware. It supports a wide range of devices and offers powerful automation, but has a steeper learning curve.
Brand-Specific Bridges
- Philips Hue Bridge for Hue lights
- Aqara hubs for Aqara sensors
- Lutron Caséta Smart Hub for Lutron switches
Some bridges also act as Matter bridges.
Local vs. Cloud Control
- Cloud control: Commands go through company servers. Requires internet.
- Local control: Commands stay on your home network. Faster and may work during internet outages.
Hubs that support local control can improve reliability and privacy.
Choosing a Hub
Consider:
- Which protocols your devices use
- Ecosystem compatibility
- Local automation support
- Ease of use vs. customization
- Community support and documentation
- Long-term support from the manufacturer
Setting Up a Hub
- Place the hub centrally, away from interference.
- Connect to your router.
- Add devices one at a time.
- Organize by room.
- Create automations.
- Update firmware.
Building Strong Mesh Networks
Zigbee, Z-Wave and Thread devices can relay signals. Plug-in devices like smart plugs often act as repeaters. Add repeaters to strengthen weak areas. See best smart plugs.
Security
Use strong passwords and 2FA, keep firmware updated and secure your network. See how to secure your smart home.
A Simple Decision Path
- List every smart device you own and its protocol.
- If everything is Wi-Fi or Matter, start with your existing speaker or display as the controller.
- If you have Zigbee devices from one brand, use that brand’s bridge or a speaker with a Zigbee hub.
- If you have Z-Wave devices or want local automations, consider Hubitat, SmartThings or Home Assistant.
- If you enjoy tinkering and want maximum flexibility, Home Assistant is worth exploring.
Questions to Ask Before Buying a Hub
- Which protocols do your current devices use?
- Does a device you already own include a hub or border router?
- Do you want automations to keep running during internet outages?
- How much time do you want to spend configuring and maintaining your system?
Backing Up Your Setup
Some hubs, including Home Assistant and Hubitat, offer backups of your configuration. Make backups before major updates and store a copy somewhere other than the hub itself. If a hub fails, a backup can save hours of re-pairing devices and recreating automations.
Keeping It Manageable
The more devices and automations you add, the more there is to maintain. Name devices consistently, group them by room, document unusual automations and avoid building fragile chains that depend on many devices at once. A smaller system that works reliably is usually more satisfying than a complicated one that breaks often.
Hubs and Matter
Many newer hubs act as Matter controllers or bridges. A Matter bridge can expose existing Zigbee or Z-Wave devices to Matter platforms, letting older devices appear in Apple Home, Google Home or Alexa. Check whether your hub supports this before replacing devices.
Hub Placement and Interference
Place hubs and border routers in open areas, ideally near the middle of your home and off the floor. Keep Zigbee hubs a little away from Wi-Fi routers, since both commonly use the 2.4 GHz band. A USB extension cable can help when a USB radio sits too close to a computer or router. Thick walls, metal appliances and aquariums can weaken signals, so add plug-in repeaters to fill gaps.
Frequently Asked Questions
Do I need a smart home hub?
Not always. Many Wi-Fi and Matter devices work without one, but hubs help with Zigbee, Z-Wave and local automation.
Is a smart speaker a hub?
Some smart speakers include hub features like Zigbee or Thread support.
What is the difference between Zigbee and Z-Wave?
Both are low-power mesh protocols, but they are not compatible with each other and need appropriate hubs.
Is Home Assistant hard to use?
It has a learning curve but offers extensive customization.
Do hubs work without internet?
Many support local control for some functions.
The Bottom Line
Smart home hubs connect devices across protocols, run local automations and improve reliability. You may not need one if you use Wi-Fi or Matter devices, but hubs are valuable for Zigbee, Z-Wave, advanced automation and local control.
