You've decided to go with Zigbee for your smart home. Good call. Now 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.

Problem is, there are at least a dozen options. USB sticks, network coordinators, ones with external antennas, ones without. Some cost $15, some cost $60. They all claim to work with Home Assistant.

So which one should you actually buy?

I've compared the most popular options based on price, reliability, firmware support, range, and how well they work with Home Assistant's two main Zigbee integrations: ZHA (Zigbee Home Automation, built-in) and Zigbee2MQTT (community favorite).

Quick Picks: The Short Answer

  • Best for most people: Sonoff Zigbee 3.0 USB Dongle Plus E ($20). Cheap, reliable, great firmware, huge community support.
  • Best official option: Home Assistant SkyConnect ($30). Plug-and-play with ZHA, also supports Thread/Matter.
  • Best for power users: SLZB-06 ($40). Ethernet-connected, so no USB interference. Remote placement anywhere in your house.
  • Best budget pick: Sonoff Zigbee 3.0 USB Dongle Plus P ($13). Older chip but still works perfectly for smaller setups.

Now let's get into the details.

What a Zigbee Coordinator Actually Does

A Zigbee coordinator is the "brain" of your Zigbee network. Every Zigbee network needs exactly one coordinator. It handles:

  • Network creation. The coordinator creates the Zigbee network that devices join.
  • Device pairing. When you put a sensor into pairing mode, the coordinator is what accepts it onto the network.
  • Message routing. Commands and sensor data flow through the coordinator to Home Assistant.
  • Network management. Keeping track of which devices are on the network, managing the mesh topology, handling encryption keys.

The coordinator plugs into your Home Assistant server, usually via USB. Some newer options connect over Ethernet or WiFi instead, which gives you more flexibility in placement.

Important distinction

A Zigbee "coordinator" is not the same as a Zigbee "hub" like the Philips Hue Bridge or IKEA DIRIGERA. Those are closed systems that only work with their own brand. A coordinator for Home Assistant is an open device that works with thousands of Zigbee devices from any brand.

ZHA vs Zigbee2MQTT: Which Integration to Use

Before picking hardware, you should know about the two ways Home Assistant talks to Zigbee devices:

ZHA (Zigbee Home Automation)

  • Built into Home Assistant. No extra software needed.
  • Easier to set up. Plug in your coordinator and follow the UI wizard.
  • Supports most popular Zigbee devices.
  • Good for beginners and people who want simplicity.

Zigbee2MQTT

  • Runs as a separate add-on alongside Home Assistant.
  • Supports more devices than ZHA (over 3,700 at last count).
  • More configuration options and advanced features.
  • Better for power users and people with unusual or cheap Tuya devices.
  • Requires MQTT broker (Mosquitto), which is one extra add-on.

The bottom line: if you're new to Home Assistant, start with ZHA. If you want maximum device compatibility or plan to have 50+ devices, Zigbee2MQTT is worth the extra setup. Both work with all the coordinators in this guide.

Home Assistant SkyConnect / Connect ZBT-1

Official Pick
Home Assistant SkyConnect (Connect ZBT-1)
~$30
Chip
EFR32MG21
Connection
USB
Antenna
PCB (internal)
Thread/Matter
Yes (with firmware switch)

The SkyConnect is the official Zigbee coordinator from Nabu Casa (the company behind Home Assistant). It's a small USB stick with a Silicon Labs EFR32MG21 chip inside.

Pros: Plug-and-play with Home Assistant. Auto-detected by ZHA. Can switch to Thread firmware for Matter devices. Backed by the HA team.

Cons: Internal antenna means slightly shorter range than dongles with external antennas. Can't run Zigbee and Thread at the same time (you pick one). Slightly pricier than the Sonoff options.

The SkyConnect is the easiest option if you're just getting started. Plug it in, Home Assistant detects it, click through the setup wizard, and you're running. No firmware flashing, no configuration files.

The Thread/Matter support is a nice bonus for future-proofing. As Matter devices become more common, you could switch this stick to Thread mode and add a second coordinator for Zigbee. Or just use it for Zigbee and handle Matter through other means.

Range is the only real weakness. The internal PCB antenna works fine in apartments and smaller homes. In a large house, you might find that devices in distant rooms struggle to connect directly. That said, if you have enough mains-powered Zigbee devices forming a mesh, range stops being an issue.

Sonoff Zigbee 3.0 USB Dongle Plus (E version)

Best Overall
Sonoff Zigbee 3.0 USB Dongle Plus E (ZBDongle-E)
~$20
Chip
EFR32MG21
Connection
USB
Antenna
External (SMA)
Thread/Matter
Yes (with firmware switch)

This is the one most Home Assistant users recommend, and for good reason. Same Silicon Labs chip as the SkyConnect, but with an external antenna and a lower price tag.

Pros: External antenna for better range. Same chip as SkyConnect (EFR32MG21). Cheaper. Works great with both ZHA and Zigbee2MQTT. Huge community and tons of guides available.

Cons: Needs a USB extension cable for best results (see setup tips). Not auto-detected quite as smoothly as SkyConnect in ZHA, but still easy.

The Sonoff E is the coordinator I'd recommend to most people. It's $10 less than the SkyConnect, has better range thanks to the external antenna, and runs the same firmware. The community support is enormous. If you run into any issue, there's a Reddit thread or forum post about it.

One thing to know: it uses the same Silicon Labs EFR32MG21 chip as the SkyConnect. This means it can also run Thread firmware if you want Matter support down the road. Same hardware, less polish in the packaging, lower price.

Sonoff Zigbee 3.0 USB Dongle Plus (P version)

Budget Pick
Sonoff Zigbee 3.0 USB Dongle Plus P (ZBDongle-P)
~$13
Chip
CC2652P
Connection
USB
Antenna
External (SMA)
Thread/Matter
No

The older brother of the E version. Uses a Texas Instruments CC2652P chip instead of Silicon Labs. Still a perfectly capable coordinator.

Pros: Cheapest option that actually works well. External antenna. Rock-solid with Zigbee2MQTT (which was originally built around TI chips). Proven over years of community use.

Cons: No Thread/Matter support. TI chip is slightly older tech. Firmware updates less frequent than Silicon Labs options.

If you just want Zigbee and don't care about Thread or Matter, the P version is all you need. It's been the community's go-to coordinator for years. Thousands of people run networks with 100+ devices on this $13 stick.

Zigbee2MQTT was originally designed around TI chips, so compatibility is excellent. ZHA supports it too, though the Silicon Labs chipsets have slightly better ZHA integration since Nabu Casa has focused their development there.

ConBee II / ConBee III

ConBee III
~$40
Chip
EFR32MG21
Connection
USB
Antenna
PCB (internal)
Thread/Matter
No (Zigbee only)

The ConBee line from Dresden Elektronik (Phoscon) has been around for years. The ConBee III uses the same EFR32MG21 chip as the SkyConnect and Sonoff E.

Pros: Comes with its own deCONZ software (alternative to ZHA/Z2M). Good build quality. Well-known brand in the HA community.

Cons: Most expensive USB option. Internal antenna (same range limitation as SkyConnect). deCONZ is a third integration to learn. No Thread support despite having the right chip.

The ConBee was the go-to recommendation a few years ago, before the Sonoff dongles showed up at half the price. It's still a solid product, but it's hard to justify the extra cost in 2026 when the Sonoff E has the same chip, an external antenna, and costs $20 less.

The one reason to consider a ConBee: if you want to use deCONZ (Phoscon) as your Zigbee integration instead of ZHA or Zigbee2MQTT. Some people prefer its UI. But for most Home Assistant users, ZHA or Z2M is the way to go.

SLZB-06 (Ethernet + USB + WiFi)

Power User Pick
SMLIGHT SLZB-06
~$40
Chip
EFR32MG21
Connection
Ethernet, USB, WiFi
Antenna
External (dual)
Thread/Matter
Yes (separate chip)

This is the fancy option. The SLZB-06 connects over Ethernet, which means you can place it anywhere in your house. No USB cable tethering it to your server.

Pros: Ethernet connection eliminates USB interference issues entirely. Place it centrally in your house for optimal coverage. Dual external antennas. Can run Zigbee and Thread simultaneously (separate chips). Web-based management interface. PoE support on some models.

Cons: More expensive. More complex setup (network configuration). Overkill for most beginners. Needs an Ethernet cable to wherever you place it.

The SLZB-06 solves two common problems at once.

First: USB interference. If your Home Assistant server is a mini PC or NUC, the USB ports are close together. USB 3.0 ports generate RF noise on the 2.4 GHz band, which is exactly where Zigbee operates. This causes dropped messages and flaky connections. With the SLZB-06, there's no USB involved. It connects over Ethernet.

Second: coordinator placement. With a USB stick, your coordinator sits wherever your server is. That's usually in a closet, in the basement, or tucked behind a TV. Not ideal for radio coverage. The SLZB-06 lets you put the coordinator in the center of your house, plugged into an Ethernet switch, where it has the best line of sight to all your Zigbee devices.

If you're running 50+ devices or live in a large house, the SLZB-06 is worth the extra $20 over a USB stick.

Tube's Zigbee Coordinator

Tube's Zigbee Coordinator (CC2652P2)
~$25
Chip
CC2652P2
Connection
USB or Ethernet
Antenna
External (SMA)
Thread/Matter
No

A community-made coordinator sold by a fellow Home Assistant user. Available in USB and Ethernet variants. Uses the TI CC2652P2 chip with an external antenna.

Pros: Made by and for the HA community. External antenna. Ethernet variant available. Good reputation on the HA forums.

Cons: Harder to buy (usually through Tindie or similar maker marketplaces). Limited stock. TI chip (no Thread). Less polished packaging.

Tube's coordinators have a loyal following in the Home Assistant community. They're handmade and sell in limited batches, so availability can be hit or miss. If you can find one in stock, it's a solid choice. But for most people, the Sonoff E is easier to buy and works just as well.

Which One Should You Buy?

Best for most people

Sonoff Zigbee 3.0 USB Dongle Plus E. $20, external antenna, Silicon Labs chip, works with ZHA and Zigbee2MQTT, future Thread support. It's the community's most recommended coordinator for a reason. You can't go wrong with this one.

If you want the easiest setup possible: SkyConnect. Plug it in and Home Assistant does the rest. You pay $10 extra for that convenience and the official support.

If you're on a tight budget: Sonoff P. $13 and it works. You lose Thread support and the newer chip, but for pure Zigbee it's still rock-solid.

If you're building a large network (50+ devices) or have a big house: SLZB-06. The Ethernet connection and central placement will make your Zigbee network significantly more reliable than any USB stick tucked behind a server.

If you want to run Zigbee and Thread simultaneously: SLZB-06. It has separate chips for both protocols. With a USB stick, you'd need two sticks (one for Zigbee, one for Thread).

Setup Tips for Any Coordinator

Use a USB extension cable

This is the number one tip in the Home Assistant community, and it's not a joke. USB 3.0 ports emit radio frequency interference on the 2.4 GHz band. Plugging your Zigbee coordinator directly into a USB 3.0 port can halve your effective range and cause random device dropouts.

A $3 USB extension cable (1 to 2 meters) moves the coordinator away from the interference zone. Many people report their Zigbee network going from "frustratingly flaky" to "perfectly stable" just by adding an extension cable.

Place it centrally (if possible)

Your coordinator doesn't need line of sight to every device (the mesh handles routing). But it helps to have it in a somewhat central location rather than in the corner of your basement. If you're using a USB stick, the extension cable gives you some placement flexibility.

Build your mesh before adding battery devices

Add your mains-powered Zigbee devices (smart plugs, in-wall switches, light bulbs) first. These devices act as routers in the mesh network. Once you have a few routers spread around the house, add your battery-powered sensors. They'll automatically connect through the nearest router.

Don't mix Zigbee coordinators

One coordinator per Zigbee network. If you want to support more devices or extend range, add more Zigbee router devices (smart plugs are perfect for this). Don't add a second coordinator thinking it'll extend the network. That creates two separate networks.

How many devices can one coordinator handle?

Technically, the Zigbee spec supports 65,000+ devices. In practice, a single coordinator handles 200 to 300 devices comfortably with proper mesh routing. Most home setups never get close to that limit. If you're worried about scale, the SLZB-06 with Ethernet has the most headroom.

The Bottom Line

For $20, the Sonoff E gives you the same Silicon Labs chip found in the official SkyConnect, an external antenna for better range, and compatibility with every Zigbee integration Home Assistant offers. It's the coordinator that most of the Home Assistant community uses, and there's a reason for that.

If you want the absolute simplest setup, spend the extra $10 on the SkyConnect. If you want the best possible performance for a larger home, the SLZB-06 at $40 is worth it for the Ethernet connection alone.

Whatever you pick, pair it with Home Assistant and a few Zigbee devices, and you'll have a smart home that's faster, more reliable, and more private than anything cloud-based.
