Three ways to connect: PoE, Wi-Fi and USB

The biggest advantage of this model is its 3-in-1 connectivity. You can run it as a PoE Z-Wave dongle over RJ45, as a wireless Wi-Fi Z-Wave dongle, or as a classic USB Z-Wave stick via the included USB-C cable. This lets you choose the setup that fits your home, server or smart home rack – PoE gives you data and power over a single cable, Wi-Fi lets you place the hub wherever Z-Wave coverage is best, and USB is handy for a direct connection to a computer, mini PC or Home Assistant box.

If you're deciding whether a simpler USB Z-Wave dongle is enough for your setup, or whether you need network connectivity too, check out the SONOFF Dongle Plus PZG23 – the USB-only version on the same Z-Wave 800 platform – or read our USB dongle comparison guide.

Z-Wave Long Range for stronger, more stable coverage

Z-Wave Long Range extends control beyond typical indoor spaces. The Dongle-MZG23 is an excellent choice for controlling devices in a garage, basement, on a patio, at a gate, in the garden, or anywhere signal is weaker. Two adjustable antennas with 3 dBi gain help improve communication stability and keep the connection reliable even in more challenging environments – and since Z-Wave runs on a different frequency than Wi-Fi, it reduces interference and improves automation reliability for sensors, switches, locks and garage doors.

Secure local control with Z-Wave S2 and a local web console

Z-Wave S2 Security provides encrypted communication between compatible devices, helping protect your smart home's data. The SONOFF Z-Wave 800 PoE Dongle Max is built for local control with no unnecessary cloud dependency – a plus for anyone who wants more privacy, faster response times and reliable operation. The built-in local web console lets you check device status, change settings, manage operational information and update firmware straight from a browser on your local network, with no extra software required.

Compatible with Home Assistant, openHAB and Z-Wave JS

The Dongle-MZG23 is ready for integration with popular open-source platforms such as Home Assistant, openHAB and Z-Wave JS. That makes it a great fit for smart home enthusiasts, advanced users and installers who need a reliable Home Assistant Z-Wave controller with room to grow. Via MQTT, device data can be shown directly on a Home Assistant dashboard and easily wired into automations. The device also offers Webhook and VPN functions for more advanced networking and automation scenarios, and if you run Zigbee devices alongside Z-Wave, the dongle can operate at the same time as a separate Zigbee dongle on the same server without conflict.

Durable aluminium housing

The SONOFF Z-Wave 800 PoE Dongle Max has an elegant, dark grey aluminium housing that helps dissipate heat and improves durability. The build is suitable for demanding spaces such as utility rooms or damper environments, and an operating range of -10°C to +60°C allows it to be used well outside a typical living area.

Who is this for

• Advanced Home Assistant, openHAB and Z-Wave JS users who want a local, cloud-free Z-Wave controller.
• Households and businesses where the server or mini PC sits out of Wi-Fi range and a stable network connection via PoE is needed.
• Smart home installers who need to place the hub exactly where Z-Wave coverage is best – in garages, larger houses or utility rooms.
• Anyone upgrading from an older Z-Wave controller who wants Z-Wave Long Range and more modern S2 security.

Use cases

• 🏠 Building a local Z-Wave network for Home Assistant with no cloud dependency and strong privacy.
• Connecting Z-Wave devices in a garage, on a patio, or anywhere outside Wi-Fi range using PoE over a single network cable.
• Extending Z-Wave range in a larger or multi-storey home with Z-Wave Long Range.
• Migrating from an existing, weaker Z-Wave USB stick to a more powerful controller with PoE and S2 security.
• Running Zigbee and Z-Wave networks side by side on one Home Assistant server in a mixed-device household.
