The SONOFF Z-Wave 800 Dongle Max (Dongle-MZG23) is a professional Z-Wave 800 controller adapter, designed primarily for open-source smart home systems such as Home Assistant, openHAB, and Z-Wave JS. With this dongle, certified sensors, switches, relays, bulbs, locks, and other smart Z-Wave devices can be integrated into local smart home systems that do not depend on the cloud.

The SONOFF Z-Wave 800 Dongle Max is based on a dual-chip architecture with ESP32D0WDR2 and EFR32ZG23, delivering high performance, fast response times, and stable Z-Wave communication. The Z-Wave 800 platform supports the advanced Z-Wave S2 security protocol and Z-Wave Long Range technology, enabling more secure and stable control over greater distances than previous Z-Wave adapters.

It can be used via Ethernet with PoE power supply, Wi-Fi connection, or as a traditional USB Type-C dongle. This allows the adapter to be placed not necessarily next to the Home Assistant server or mini PC, but wherever Z-Wave network coverage is optimal. With PoE, a single Ethernet cable provides both data connection and power.

The built-in local web console provides easy access to device settings, operating modes, firmware updates, and network configuration. Through the web interface, users can configure the device from a browser without installing separate software. The system is optimized for local operation, so data transmission does not require cloud services.

The SONOFF Z-Wave 800 Dongle Max is designed for advanced users building Home Assistant, openHAB, and Z-Wave JS systems. It is an ideal choice for creating a scalable, long-term Z-Wave network where local control, secure communication, flexible installation, and open integration are important.
