The Homelab Bench is reader-supported. As an Amazon Associate we earn from qualifying purchases; this article contains affiliate links.

The Home Assistant Connect ZBT-2 is the easiest pick for most people — plug it in, Home Assistant finds it automatically, and firmware updates happen in the background. If you want to free your coordinator from USB altogether, the SMLIGHT SLZB-06MG24 is the PoE unit the homelab crowd has settled on. Runners-up exist for tighter budgets and edge cases, and they’re worth knowing.

1. Home Assistant Connect ZBT-2 — Best overall

The Home Assistant Connect ZBT-2 is the official Zigbee coordinator and Thread border router from Nabu Casa. It runs a Silicon Labs MG24 Arm Cortex-M33 at 78 MHz with 256 kB RAM and 1536 kB flash, paired with an ESP32-S3 as the USB-to-serial bridge. It is the successor to the SkyConnect, which Nabu Casa has discontinued.

Strengths

• Zero-friction setup. When you plug in the ZBT-2, Home Assistant discovers it automatically; you then choose whether to set it up as a Zigbee coordinator or as a Thread adapter. The process updates firmware automatically and completes ZHA setup in your Home Assistant instance.
• Works with both Zigbee stacks. It has been tested working with ZHA, zigpy-cli, Zigbee2MQTT, matter.js, and OpenThread Border Router.
• Thread-ready hardware. Connect ZBT-2 gives you the flexibility to run either a Zigbee or Thread network, so if you start adding Matter-over-Thread devices later you don’t need to buy anything new — just reflash.

Drawbacks

• One protocol at a time. Connect ZBT-2 cannot do both Zigbee and Thread simultaneously. Though the hardware makes it technically possible, Nabu Casa found this functionality works inconsistently and causes device stability issues — they don’t plan to implement it. You’ll need a second stick if you want both protocols running concurrently.
• Still a USB device. Placement relative to your server matters. Plug it into a USB extension cable rather than directly into your server, because USB 3.0 ports emit electromagnetic interference on the 2.4 GHz band that directly overlaps with Zigbee.

2. Sonoff Dongle Plus MG24 — Best budget MG24 stick

The Sonoff Dongle Plus MG24 is the official successor to the Sonoff ZBDongle-E. It pairs the same Silicon Labs MG24 family the ZBT-2 uses with double the flash and four times the RAM of the older ZBDongle-E, and includes a USB extension cable in the box.

Strengths

• Highest antenna gain of any USB stick here. Based on the Silicon Labs EFR32MG24 SoC, its real selling point is radio performance: it pushes the legal limit with +20 dBm output power paired with a +4.5 dBi external antenna — the highest out-of-the-box gain of any USB coordinator on this list.
• Wall-penetrating range. If you need a stick that can punch through thick walls or cover dead zones that standard +3 dBi dongles can’t reach, this is the one to get.
• Zigbee2MQTT recommended. Zigbee2MQTT’s adapter guide lists it among its recommended EmberZNet adapters, and Sonoff publishes Zigbee, OpenThread, and other firmware options for it.

Drawbacks

• Firmware flash required for Zigbee2MQTT. Zigbee2MQTT users need to be comfortable with one firmware flash — skipping the step leaves Zigbee2MQTT on a deprecated driver. ZHA users are unaffected.
• Still a USB-only stick. The included extension cable is there for good reason — Zigbee is highly susceptible to interference when plugged directly into a server’s USB port. If your server is in a cupboard surrounded by metal, look at a PoE option instead.

3. Sonoff ZBDongle-E — Best for the tightest budget

The ZBDongle-E is based on the Silicon Labs EFR32MG21 and has been the default Zigbee dongle recommendation for years. If you don’t need the latest EFR32MG24 chip, it remains the best value-for-money coordinator on this list. The community base behind it is enormous, which means guides, Zigbee2MQTT quirk threads, and forum troubleshooting are never more than a search away. We compare it with the other low-cost options in our best budget Zigbee hubs roundup.

Strengths

• Massive community support. It has a large, established user base, which means better guides, easier troubleshooting, and confidence you’re not buying into something obscure.
• Works with both ZHA and Zigbee2MQTT. No firmware flash required for ZHA users, and Zigbee2MQTT support with the ember driver is mature and fully recommended.
• Proven long-term reliability. The ZBDongle-E held the top community recommendation spot for over two years — a track record very few dongles can match.

Drawbacks

• Older chipset. The EFR32MG21 is a generation behind the MG24 found in the ZBT-2 and Dongle Plus MG24, meaning lower RAM and flash. This only matters if you’re planning a very large network of 150 or more devices.
• USB interference still applies. Pick up a USB extension cable at the same time — direct-port connections to a server often cause interference that an extension cable resolves.

4. SMLIGHT SLZB-06MG24 — Best for large networks and awkward server placement

The SMLIGHT SLZB-06MG24 connects Zigbee 3.0 devices to Home Assistant over your local network via Ethernet, Wi-Fi, or USB — it replaces USB Zigbee dongles by allowing placement anywhere in your home where Zigbee signal is strongest. The MG24 variant specifically uses the current-gen Silicon Labs EFR32MG24 chipset for maximum headroom.

Strengths

• Flexible power and connectivity. It supports both Power over Ethernet and USB Type-C power, offering flexibility for varied installation environments. Run a single PoE cable to a central hallway and your RF coverage problem disappears.
• Pre-flashed, web dashboard included. The device comes pre-flashed for easy setup. The built-in web dashboard lets you update firmware and monitor the coordinator without touching Home Assistant.
• Scales to large deployments. Best for users who need to manage networks of 200 or more devices, want maximum flexibility in coordinator placement, or need to connect remote Zigbee networks via VPN.

Drawbacks

• Premium price. The SLZB-06MG24 costs more than USB-only alternatives. The additional features justify the investment for serious smart home enthusiasts, but it’s overkill for a 20-device flat.
• Confusing product lineup. Even experienced reviewers have reported trouble differentiating between SMLIGHT’s many models. Double-check you’re ordering the MG24 variant specifically before completing your purchase.

5. Sonoff Dongle Max MG24 — Best mid-range PoE option

The Sonoff Dongle Max MG24 is the newest member of Sonoff’s Zigbee coordinator lineup. Like the Dongle Plus, it uses the Silicon Labs EFR32MG24 chipset and supports both Zigbee and Thread, but Sonoff has added Ethernet connectivity and Power over Ethernet support — a direct answer to users who wanted PoE from Sonoff to compete with the SMLIGHT line.

Strengths

• Eliminates USB interference via PoE. Ethernet connectivity and PoE support allow more flexible installations and remove the interference problems inherent to USB port placement.
• MG24 headroom at a lower entry point. It offers stronger processing power, better range, and higher antenna gain than the older ZBDongle-E generation, with seamless compatibility for both Zigbee2MQTT and ZHA.
• Thread support included. Like the rest of Sonoff’s MG24 line, it can be reflashed to act as a Thread border router if your needs change later.

Drawbacks

• Newer to market, smaller community. Being newer than the SMLIGHT SLZB-06 series means fewer community troubleshooting threads and less real-world long-term feedback.
• PoE switch or injector required. You’ll need a PoE-capable network switch or PoE injector to take advantage of the PoE functionality — an extra cost and complexity point for users without managed switching already in place.

How we chose

Every coordinator on this list was evaluated against three criteria. First, chipset generation: obsolete coordinators have been removed from consideration in favour of the EFR32MG24 standard for high-performance Zigbee networks, with the ZBDongle-E retained as a value exception given its proven EFR32MG21 track record. Second, integration quality: each device had to work reliably with both ZHA and Zigbee2MQTT — good support means easier setup, better firmware guidance, and more community troubleshooting if something goes wrong. Third, placement practicality: placement matters a lot — a great coordinator shoved behind a metal server case is often worse than a slightly older one placed properly with an extension cable or over Ethernet. That’s why both USB and PoE options appear here.

FAQ

Do I need a Zigbee hub if I already have Home Assistant running?

Yes — Home Assistant is the software, but it still needs a radio to talk to Zigbee devices. You need a Zigbee coordinator (sometimes called a hub, dongle, or stick) to plug into your Home Assistant setup; the coordinator is the bridge between your Zigbee devices and Home Assistant. The USB sticks above plug directly into the machine running HA; PoE models connect over your LAN instead.

Should I use ZHA or Zigbee2MQTT?

ZHA is built into Home Assistant — no additional services are needed, devices appear directly in Home Assistant, and the setup wizard is point-and-click. Zigbee2MQTT bridges your Zigbee network to MQTT; it supports the widest range of devices — over 3,500 supported models — and provides granular device configuration. If you’re new to Home Assistant, start with ZHA. If you hit a device compatibility wall or want deeper control, migrate to Zigbee2MQTT — all the coordinators here support both.

Can one coordinator handle both Zigbee and Thread at the same time?

No. Connect ZBT-2 cannot do both Zigbee and Thread simultaneously — Nabu Casa previously tested multiprotocol thoroughly with an earlier adapter and found it caused inconsistent operation and device stability issues. They consider multiprotocol unsuitable for home use and don’t plan to implement it. The same limitation applies across all coordinators on this list. If you need both protocols running concurrently, buy two coordinators — one dedicated to each protocol.
