About this item
The SZKOSTON Dongle Plus is a versatile Zigbee USB device designed to act as an efficient Zigbee coordinator for smart home networks. Compatible with popular open-source platforms such as Home Assistant and zigbee2mqtt, this dongle plus allows seamless local control over a wide array of Zigbee devices without the need for multiple vendor-specific hubs.
Equipped with pre-flashed coordinator firmware, the dongle plus supports firmware updates and can be converted into a router to extend the Zigbee network range. It supports numerous Zigbee-compatible devices including ZBMINI-L, SNZB01, SNZB02, SNZB03, SNZB04, S26R2ZB, and S40 LITE ZB.
This zigbee USB dongle operates smoothly across multiple platforms such as Linux, Ubuntu, Raspbian, Windows, and macOS (the latter two requiring driver installation). Its universal compatibility benefits users looking for a reliable and flexible Zigbee gateway solution.
Key technical highlights include:
- Pre-flashed with EZSP v8 (EmberZNet Serial Protocol version 8) firmware
- Compatible with ZHA integration in Home Assistant and early-stage zigbee2mqtt support
- Based on Silicon Labs EFR32MG21 + CH340E chipset
- +20dBm output power with PCB antenna for strong signal transmission
- Durable plastic shell for protection and ease of use
- Supports OTA updates via UART (using BOOT and nRST buttons)
- Standard baud rate of 115200 for serial communication
The hardware foundation comprises the Silicon Labs EFR32MG21 Series 2 multiprotocol wireless SoC and the WCH CH340E USB to Serial/UART bridge controller. Despite its compact PCB antenna, the device achieves excellent radio performance with a high output gain and sensitivity, making it suitable for effective Zigbee coordination or routing in varied smart home environments.
This dongle plus comes with an unsigned EmberZNet 6.7.9 Zigbee NCP application firmware and standard Silabs Gecko bootloader for easy recovery and firmware customization via USB. Both official and community firmware versions are widely used to ensure up-to-date functionality.
