Why You Need a Smart Home Hub
If your smart home consists of a few bulbs and a voice speaker, you may not need a dedicated hub — yet. But once you start mixing devices from different brands, adding automations, and wanting your devices to work together reliably, a smart home hub becomes essential.
A hub centralises control of all your devices under one platform, enables local processing (so your automations still work when the internet is down), and lets you create complex automations that single-brand ecosystems simply can't do. It's the difference between a collection of smart gadgets and an actual smart home.
In 2025, the hub market has matured significantly. Matter has simplified cross-brand compatibility, but a local hub still offers advantages in speed, reliability, privacy, and automation power that cloud-only setups can't match. Here are the four best options right now.
1. Home Assistant Green — Best Overall
Home Assistant Green
The official Home Assistant plug-and-play hub. Pre-installed with Home Assistant OS, ready to run in minutes. Supports 3,000+ integrations, local processing, and full customisation.
Check Price on AmazonHome Assistant Green is the gateway to the world's most powerful open-source smart home platform. It comes with Home Assistant OS pre-installed on an Allwinner H616 processor with 4GB RAM and 32GB eMMC storage — enough horsepower for hundreds of devices and complex automations.
What makes Home Assistant stand apart is its sheer scope: over 3,000 official integrations covering virtually every smart home brand, protocol, and service. Zigbee, Z-Wave (with a dongle), Matter, Thread, Wi-Fi, Bluetooth — it handles everything. And because it runs locally on your network, automations fire in milliseconds and continue working even when your internet is down.
The Green is designed for users who want the power of Home Assistant without the complexity of running it on a Raspberry Pi or mini PC. Plug it in, navigate to homeassistant.local in your browser, and you're up and running in under 10 minutes. Configuration still has a learning curve, but the UI has improved dramatically and there's an enormous community for support.
Best for: Anyone who wants maximum flexibility, privacy, and automation power. Ideal for tech-comfortable users willing to invest a few hours to learn the platform.
2. Samsung SmartThings Hub — Best for Beginners
Samsung SmartThings Hub
Cloud-connected smart home hub with Zigbee, Z-Wave, and Matter support. Simple app-based setup with broad device compatibility.
Check Price on AmazonSamsung SmartThings has been a mainstay of the smart home market for over a decade. The current hub supports Zigbee, Z-Wave, and Matter, and integrates deeply with Samsung's own ecosystem of TVs, washing machines, and SmartThings-branded devices. Setup is via the SmartThings app — clean, intuitive, and accessible to non-technical users.
The trade-off is cloud dependency. Most SmartThings automations run through Samsung's servers, which means latency and a reliance on cloud availability. Samsung has expanded local processing in recent years, but it still lags behind Home Assistant and Hubitat in this regard. It's also less flexible — you're working within the SmartThings ecosystem rather than freely integrating anything.
Best for: Samsung ecosystem users, beginners who want a simple setup, and households with Samsung appliances.
3. Aqara Hub M3 — Best for Apple Users
Aqara Hub M3
Matter-compatible hub with Zigbee 3.0, Matter over Thread, and deep HomeKit integration. Works as a Thread border router.
Check Price on AmazonAqara's Hub M3 is the standout choice for Apple HomeKit users. It supports Zigbee 3.0, Matter over Thread, and serves as a Thread border router — making it one of the most future-proof hubs available at its price point. It natively bridges Aqara's extensive Zigbee device catalogue into HomeKit, which is a genuine advantage given how limited native HomeKit-certified hardware remains.
The M3 also has an IR blaster and supports IR control of TVs and ACs, adding a useful layer of legacy device control. Automation through the Aqara app is solid, though it can't match the depth of Home Assistant. If you live in the Apple ecosystem and want reliable HomeKit integration with Zigbee devices, the M3 is the best option available.
Best for: Apple ecosystem users who want HomeKit + Zigbee integration without complexity.
4. Hubitat Elevation — Best for Power Users
Hubitat Elevation C-8 Pro
Fully local smart home hub with Zigbee, Z-Wave, and Matter. Rule-based automation engine with no cloud dependency.
Check Price on AmazonHubitat Elevation is the closest competitor to Home Assistant for users who want 100% local processing without the open-source complexity. All automations, device control, and dashboards run on local hardware — there's no cloud requirement. The automation engine (Rule Machine) is extremely powerful, capable of complex conditional logic that rivals Home Assistant's scripting system.
The ecosystem is more limited than Home Assistant's 3,000+ integrations, but Hubitat covers all the major protocols: Zigbee, Z-Wave, LAN, and Matter. The UI is functional but dated, and the learning curve is real. For users who want local-first control with serious automation depth, Hubitat delivers.
Best for: Privacy-conscious power users who want 100% local control with serious automation capabilities.
