OPERATING MANUAL

 

1. DESCRIPTION

The NOUS E16 Zigbee2MQTT USB Dongle is a high-performance USB adapter designed for those looking to build a reliable and scalable smart home system. It connects to a PC/mini-PC/server (e.g., running Home Assistant) and turns it into a universal Zigbee gateway (coordinator). In other words, it serves as the “hub” of the Zigbee network, through which sensors, relays, lights, buttons, etc., from various brands can be connected – without the need to purchase separate proprietary hubs.

The aluminum housing minimizes electromagnetic interference from surrounding devices, ensuring signal integrity, and effectively dissipates heat under high loads, preventing freezes. Ready to use right out of the box

 

Intelligent “Direct-Flash” firmware (no need to open the case). Automatic entry into Bootloader mode: you no longer need to open the device's case and press the tiny physical “Flash” button to update the firmware. The new circuitry allows the system to detect the flashing mode directly via USB.
