What Is a Smart Home Hub and Do You Need One?
A smart home hub is a central controller that lets your smart devices talk to each other — and to you — regardless of brand. Without a hub, each device typically requires its own app and cloud service. A hub consolidates control, enables local automation (no internet required), and lets devices from different brands work together seamlessly.
In 2025, the landscape has shifted significantly with the arrival of Matter, the cross-platform smart home standard backed by Apple, Google, Amazon, and others. Matter-compatible devices should theoretically work with any Matter hub. In practice, many older devices still use proprietary protocols (Zigbee, Z-Wave, Wi-Fi), and a capable hub that bridges these is still very valuable.
You need a hub if you: own devices from multiple brands, want local automations that work without internet, want Zigbee or Z-Wave device support, or want voice + app + physical control without being locked to one ecosystem.
1. Home Assistant Green — Best Overall Smart Home Hub
Home Assistant Green — $99
Open-source smart home controller. Local processing, 3,000+ integrations, no subscription, Matter + Thread support, supports Zigbee/Z-Wave via USB dongles. The most powerful hub available at any price.
Check Price on AmazonThe Home Assistant Green is a purpose-built mini computer running Home Assistant OS — the most capable smart home platform in existence. At $99, it's plug-and-play for Home Assistant: connect power and ethernet, browse to homeassistant.local, and you're running a full Home Assistant instance in under 10 minutes. No tinkering, no Raspberry Pi image flashing, no SD card corruption worries.
Why Home Assistant Green Is Our Top Pick
- 3,000+ integrations: Supports virtually every smart home device and service — Philips Hue, IKEA Trådfri, Sonos, Ring, Nest, LIFX, robot vacuums, CCTV, energy monitors, and thousands more
- 100% local processing: Automations run even if your internet is down. No cloud dependency, no monthly fees
- Matter + Thread controller: Acts as a Thread border router and Matter controller out of the box (requires optional USB Thread dongle for Thread)
- Zigbee + Z-Wave via USB: Add a $25–$30 USB Zigbee dongle (e.g., Sonoff Zigbee 3.0 USB Dongle Plus) and you have a full Zigbee coordinator built in
- Privacy-first: Your data stays on your hardware. No Alexa, no Google, no cloud processing
- Active development: Home Assistant releases major updates monthly with new features and integrations
- Hardware: Quad-core ARM Cortex-A55, 4GB RAM, 32GB eMMC storage — more than enough for thousands of devices and complex automations
The catch: Home Assistant has a learning curve. Setting up advanced automations, custom dashboards, or integrating non-standard devices takes time and some technical willingness. It's not a "just plug it in and it works" experience — though the Green gets you closer to that than any previous HA hardware.
Best for: Anyone who wants the most capable, future-proof, privacy-respecting smart home hub without paying more than $99.
2. Hubitat Elevation C-8 Pro — Best for Zigbee & Z-Wave Users
Hubitat Elevation C-8 Pro — ~$130
Built-in Zigbee and Z-Wave radios, local automation, Matter controller, no subscription required. Best for users with large Zigbee/Z-Wave device libraries who want local reliability.
Check Price on AmazonThe Hubitat Elevation C-8 Pro (~$130) is the go-to choice for users with a significant investment in Zigbee and Z-Wave devices who want a reliable, locally-processed hub without building out a full Home Assistant setup. Unlike the Home Assistant Green, the C-8 Pro has built-in Zigbee and Z-Wave radios — no USB dongles required.
Key Specs and Features
- Zigbee radio: Built-in Zigbee 3.0
- Z-Wave radio: Built-in Z-Wave 700 series
- Matter: Yes — Matter controller
- Processing: Fully local — automations work without internet
- Device compatibility: 5,000+ supported devices
- Dashboards: Built-in and community dashboards available
- No subscription: One-time purchase, all features included
- Voice assistants: Alexa, Google Home, Siri Shortcuts (no native HomeKit)
Hubitat's automation engine is powerful, with rule-based and simple automation builders that don't require coding knowledge. The community is active and helpful, with dozens of custom drivers for devices not officially supported. The trade-off versus Home Assistant: fewer integrations overall (around 5,000 vs 3,000+ official HA integrations — but HA's community integrations extend this massively), and a less modern UI.
Best for: Users with 20+ Zigbee/Z-Wave devices who want plug-in simplicity without building a Home Assistant server from scratch.
3. Aqara Hub M3 — Best for Zigbee Device Networks
Aqara Hub M3 — ~$60
Zigbee 3.0 hub with Thread border router, native Apple HomeKit support, Matter controller, IR blaster, Alexa & Google Home compatible. Ideal for Aqara device ecosystems and HomeKit users.
Check Price on AmazonThe Aqara Hub M3 is the best choice at ~$60 for users who are building out an Aqara device ecosystem (Aqara sensors, locks, switches, cameras) and want native Apple HomeKit support alongside Alexa and Google Home. At $60, it's half the price of the Hubitat C-8 Pro and a third the price of the Home Assistant Green.
What Makes the Aqara Hub M3 Stand Out?
- Native Apple HomeKit: Works directly in the Apple Home app — no bridge or workaround needed
- Thread Border Router: Built-in Thread radio acts as a border router for Thread devices (Eve, Nanoleaf, etc.)
- Matter Controller: Controls Matter devices from the Aqara app
- Zigbee 3.0: Connects up to 128 Aqara Zigbee devices directly
- IR Blaster: Controls TVs, air conditioners, and other IR-remote devices via the app
- Sub-gigahertz radio: Connects Aqara's own sub-GHz sensors for extended range
- No subscription: Local automation for Aqara devices works without cloud
The limitation: The Aqara Hub M3 works best as a hub for Aqara devices specifically. It won't control Philips Hue, IKEA Trådfri, or other Zigbee brands natively — Zigbee is locked to the Aqara device library. For cross-brand Zigbee control, you need the Hubitat or Home Assistant.
Best for: Apple ecosystem users building out Aqara sensor networks who want Thread, Matter, and HomeKit in a compact $60 hub.
4. Samsung SmartThings Hub v3 — Best for Samsung Ecosystem
Samsung SmartThings Hub v3 — ~$60
Zigbee, Z-Wave, and Wi-Fi hub with built-in Matter controller. Best integration with Samsung appliances, SmartThings app, and ADT security. Alexa, Google Home, and Bixby compatible.
Check Price on AmazonThe Samsung SmartThings Hub v3 (~$60) is the right choice if you're already in the Samsung ecosystem — Samsung TVs, washing machines, refrigerators, air conditioners — and want a hub that integrates all of them natively with your smart home. SmartThings has evolved from a simple hub into a full platform, with cloud automations, local routines, and Matter controller support.
SmartThings v3 Key Features
- Radios: Zigbee 3.0, Z-Wave Plus (650 series), Wi-Fi, Bluetooth LE
- Matter: Yes — Matter controller, Thread border router (Thread in newer firmware)
- Samsung integration: Native integration with Samsung TVs, Family Hub fridges, washers/dryers, and air purifiers
- Voice assistants: Alexa, Google Home, Bixby
- Local processing: Basic routines run locally; complex automations may need cloud
- No subscription: Core features are free; some advanced features are optional
The SmartThings platform has had a turbulent history (Samsung shut down classic SmartThings in 2022 and migrated everyone to the new app), and the current platform still has rough edges in automation complexity versus Home Assistant or Hubitat. However, for Samsung-heavy households, the depth of Samsung appliance integration is genuinely impressive and unmatched by any other hub.
Best for: Samsung appliance owners who want their washing machine, TV, and smart sensors in one app with Alexa and Google Home.
5. Amazon Echo (4th Gen) — Best Plug-and-Play Entry Point
Amazon Echo (4th Gen) — ~$50
Zigbee hub, Thread border router, Matter controller, Alexa built-in, spherical design. The easiest smart home hub to set up — perfect for beginners or Alexa-first households.
Check Price on AmazonThe Amazon Echo 4th Gen (~$50) is the easiest smart home hub to get started with — and at $50, it's also the most affordable option here. Unlike the other hubs on this list, the Echo is primarily a smart speaker with hub capabilities built in. You're getting Zigbee, Thread border router, and Matter controller functionality bundled into a device you'd likely buy for Alexa anyway.
What the Echo Can (and Can't) Do as a Hub
- Zigbee hub: Connects Zigbee devices (Philips Hue, IKEA Trådfri, Sengled, and others) natively without a separate bridge
- Thread border router: Enables Thread devices (Eve, Nanoleaf) to connect via Matter
- Matter controller: Controls Matter-certified devices via the Alexa app
- Alexa Routines: Time-based, voice-triggered, and device-triggered automations
- No subscription for basic use
- NOT HomeKit compatible: Apple users should pick Aqara M3 instead
- No Z-Wave: If you have Z-Wave locks or sensors, you'll need a different hub
- Cloud-dependent: Most automations require internet connectivity
Best for: Smart home beginners, renters, or Alexa-first households who want hub capabilities without a dedicated hub device or technical setup.

Frequently Asked Questions
Do I still need a smart home hub if I use Matter devices?
Matter devices still need a Matter controller to be controlled via automations and integrations. Every hub on this list serves as a Matter controller. Where Matter helps is device compatibility — you no longer need a brand-specific hub (like a Philips Hue Bridge) just to use a single brand's devices.
What is the difference between a Thread border router and a Matter controller?
Thread is a low-power mesh radio protocol used by some devices (Eve, Nanoleaf, certain sensors). A Thread border router bridges the Thread network to your Wi-Fi/ethernet network so devices on Thread can be controlled over the internet. A Matter controller is the software layer that actually controls and automates Matter devices — you need both for Thread-based Matter devices.
Can Home Assistant Green replace a Philips Hue Bridge?
Yes — Home Assistant has a native Philips Hue integration that can control Hue lights directly via the Hue Bridge (which you keep), or you can migrate Hue bulbs directly to the HA Zigbee coordinator (removing the need for the Hue Bridge entirely). Both approaches work well.
Is there a monthly subscription fee for any of these hubs?
No — all five hubs on this list offer their core functionality for a one-time purchase price with no mandatory subscription. Home Assistant has an optional Home Assistant Cloud (Nabu Casa) subscription at ~$6.50/month for easy remote access and voice assistant integration, but it's not required for local use.
Can I use multiple smart home hubs together?
Yes — in fact, many users run Home Assistant alongside a Hue Bridge, an Aqara hub, and an Echo. Home Assistant is particularly good at this, integrating all other hubs and their devices into one unified interface. Matter is designed to make multi-hub setups even simpler by standardising cross-controller communication.
What is the best smart home hub for renters?
The Amazon Echo 4th Gen (~$50) is the best hub for renters — it's easy to move, requires no wiring, and doesn't require installing anything permanent. The Aqara Hub M3 (~$60) is a great second choice if HomeKit matters to you, since it's equally portable and supports Zigbee sensors (like door/window sensors) that don't require installation holes.
Is Home Assistant too complicated for beginners?
Home Assistant has improved dramatically in terms of ease of use, and the Home Assistant Green makes the initial setup genuinely straightforward. However, complex automations, custom integrations, and advanced dashboards still require time and patience. If you're not technically inclined, start with the Echo or SmartThings, then graduate to Home Assistant when you're ready to go deeper.
