What is Home Assistant?
Home Assistant is an open-source smart home management platform that enables the integration of hundreds of different devices and technologies into a single, centralized system. It operates locally —without the need for a cloud connection—ensuring a high level of privacy, security, and reliability . With Home Assistant, you can control lighting, heating, blinds, alarms, multimedia, and many other devices via a mobile app, automations, or voice commands . The system is continually developed by a global community and supported by Nabu Casa, the creator of official devices such as Home Assistant Green and Yellow .
The manufacturer has released experimental firmware that allows the Home Assistant Connect ZBT-2 module to function as a network repeater. This enables the device to extend network coverage and improve the stability and responsiveness of communication with devices located farther away from the main Home Assistant hub. The feature is currently available as part of an experimental firmware release and may be particularly useful in larger smart home installations where signal dead zones can occur.
The optimized antenna and USB Type-C connector ensure wide range and reliable communication.

Question: Im planning to get into smart homes for good, but Im annoyed by the "thousands" of Zigbee gateways. Does this device (together with Home Assistant) allow you to connect multiple devices that support the Zigbee protocol without the need to use manufacturers gateways?
