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 environments. With this dongle, Z-Wave certified sensors, switches, relays, bulbs, locks, and other smart devices can be integrated into local, cloud-independent smart home systems.
The SONOFF Z-Wave 800 Dongle Max is based on a dual-chip architecture with ESP32D0WDR2 and EFR32ZG23, providing 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 safer, more stable, and longer-range control than previous-generation 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 where Z-Wave network coverage is optimal.
With PoE, a single Ethernet cable provides both data connection and power supply. If no PoE infrastructure is available, the device can also be powered via USB-C while connecting to the network through Ethernet or Wi-Fi.
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 long-term expandable Z-Wave network where local control, secure communication, flexible installation, and open integration are important.
