Sonoff Dongle Max MZG23 – Z-Wave 800 adapter with PoE, Wi-Fi, and USB

Product detailed description

📡 Z-Wave 800 Coordinator for Professional Smart Home

SONOFF Z-Wave 800 PoE Dongle Max (Dongle-MZG23) is a powerful Z-Wave coordinator designed for advanced users seeking a reliable, fast, and locally controlled smart home. This Z-Wave adapter combines Ethernet connectivity (with PoE support), Wi-Fi, and USB, offering exceptionally flexible installation for apartments, family houses, utility rooms, basements, garages, and larger smart home projects.

The device utilizes a powerful dual-chip architecture (ESP32D0WDR2 + EFR32ZG23), delivering fast local response, stable operation, and high resistance to interference. Thanks to support for the Z-Wave S2 security protocol and Z-Wave Long Range (ZWLR) technology, the Dongle-MZG23 is an ideal solution for those needing a secure, stable, and easily expandable Z-Wave smart home hub.

Three Connectivity Modes: PoE, Wi-Fi, and USB

The biggest advantage of this model is its 3-in-1 connectivity. You can use the device as a PoE Z-Wave dongle connected via RJ45, a wireless Wi-Fi Z-Wave dongle, or a traditional USB Z-Wave adapter via the included USB Type-C cable. This allows you to choose the setup method exactly according to your home, server, or smart home cabinet needs – PoE provides both data connection and power through a single cable, Wi-Fi allows placement wherever Z-Wave coverage is best, and USB is convenient for direct connection to a computer, mini PC, or Home Assistant.

If you are deciding whether a simpler USB Z-Wave dongle is sufficient for your project or if you also need network connectivity, check out the SONOFF Dongle Plus PZG23 – a USB version on the same Z-Wave 800 platform – or read our USB dongle comparison overview.

Z-Wave Long Range for Stronger and More Stable Range

Z-Wave Long Range technology extends device control capabilities beyond standard indoor spaces. The Dongle-MZG23 is an excellent choice for controlling devices in garages, basements, patios, at gates, in gardens, or in areas with weaker signals. Two adjustable 3 dBi gain antennas help improve communication stability and ensure a reliable connection even in complex environments – and since Z-Wave operates on a different frequency than standard Wi-Fi, the risk of interference is reduced, increasing automation stability for sensors, switches, locks, and garage doors.

Secure Local Control with Z-Wave S2 and Local Web Console

Z-Wave S2 Security provides encrypted communication between compatible devices, helping protect your smart home data. The SONOFF Z-Wave 800 PoE Dongle Max is designed for local control without unnecessary cloud dependency, which is appreciated by users who require higher privacy, fast response times, and reliable operation. The integrated local web console lets you monitor device status, adjust settings, manage operational info, and update firmware directly within your local network via a web browser – no additional software required.

Compatibility 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. This makes it an ideal solution for smart home enthusiasts, advanced users, and installers who need a reliable Home Assistant Z-Wave coordinator that is ready for expansion. Using MQTT, device parameters can be displayed directly on the Home Assistant dashboard and easily integrated into automations. Additionally, the device features Webhook and VPN capabilities for advanced networking and automation scenarios. If you use Zigbee devices alongside Z-Wave, this dongle can run simultaneously with a separate Zigbee dongle on the same server without conflict.

Durable Aluminum Body

The SONOFF Z-Wave 800 PoE Dongle Max features an elegant aluminum body in dark gray, which helps dissipate heat and increases durability. The design is suitable for demanding spaces like utility rooms or humid environments, and an operating temperature range of -10 °C to +60 °C allows deployment outside standard living areas.

Who Is This Product For?

• For advanced **Home Assistant**, openHAB, and Z-Wave JS users who want a local, cloud-free Z-Wave coordinator.
• For homes and businesses where the server or mini PC is located outside Wi-Fi range and requires a stable network connection via PoE.
• For smart home installers needing flexible gateway placement where Z-Wave signal is optimal – in garages, larger houses, or utility rooms.
• For users upgrading from an older Z-Wave controller who want to take advantage of Z-Wave Long Range and modern S2 security.

Use Cases

• Building a local Z-Wave network for Home Assistant without cloud dependency and with high privacy.
• Connecting Z-Wave devices in garages, on patios, or out of Wi-Fi range using PoE over a single network cable.
• Extending Z-Wave network range in larger or multi-story houses using Z-Wave Long Range.
• Migrating from an existing, weaker Z-Wave USB stick to a more powerful coordinator supporting PoE and S2 security.
• Running Zigbee and Z-Wave networks simultaneously on a single Home Assistant server in a mixed-device environment.
