ZBDongleE Bridge Why you need it Centralizes control of Zigbee 3.0 devices from multiple brands so you can manage lights, sensors, switches and more from a single automation platform. Improves reliability and range for dense smarthome setups, reducing dropped devices and flaky automations. Acts as an MQTT bridge, enabling stable, bidirectional data flow between Zigbee devices and opensource home automation systems for advanced automation and monitoring. Key features and benefits Zigbee 3.0 compatibility: Works with a wide range of Zigbee 3.0 devices from various brands, letting you add and manage multiple subdevices through opensource automation platforms. Long communication range: Designed for communication distance up to 400M in unobstructed environments to extend coverage across larger homes or detached structures. Strong wireless performance: Operates at 2.4GHz–2.48GHz and supports up to 128 connected devices with a robust 18.6 signal strength for consistent performance. Enhanced antenna and construction: Specially designed antenna plus an aluminum shell minimize external interference and help maintain stable connections throughout your network. MQTT bridge functionality: Facilitates smooth data exchange between devices and your automation system, enabling reliable telemetry, state reporting, and control in complex setups. Flexible placement: Includes a 1.5 m data cable so you can position the USB dongle where signal is strongest, avoiding obstacles and improving network coverage without moving your host device. USB form factor: Compact dongle design for easy installation on PCs, home automation hubs, or singleboard computers. How it solves common problems Eliminates weak spots: Move the dongle with the included 1.5 m cable to a central or elevated location to remove dead zones and improve mesh performance. Reduces interference and instability: Aluminum housing and optimized antenna reduce noise and help keep dozens of devices reliably connected. Simplifies integration: MQTT bridge support and compatibility with opensource platforms make it straightforward to add Zigbee devices to Home Assistant, NodeRED, OpenHAB, or other systems without vendor lockin. Materials, compatibility and performance summary Model: ZBDongleE Bridge Compatibility: Zigbee 3.0 devices from various brands; integrates with opensource home automation platforms Frequency: 2.4GHz–2.48GHz Maximum connected devices: Up to 128 Signal strength: 18.6 Range: Up to 400M in unobstructed environments Housing: Aluminum shell Cable: Included 1.5 m data cable Interface: USB dongle Practical use scenarios Multiroom sensor network: Place the ZBDongleE Bridge centrally and connect temperature, motion, and door sensors from different manufacturers. Use your opensource platform to consolidate data, trigger automations, and log historical metrics via MQTT. Garage or garden extension: Use the 1.5 m cable to position the dongle near a window or doorway to reliably reach devices in a garage, shed, or backyard that were previously out of range. Unified smart lighting and security: Add Zigbee lights, switches, and locks from multiple brands to a single automation hub. The dongle's MQTT bridge ensures consistent state updates and control for complex scenes and security routines. What to expect in everyday use Stable connections for dozens of devices with fewer retries and lost messages. Clear integration path to opensource platforms via MQTT for visibility and control. Flexible placement to optimize coverage without reconfiguring the entire network. Technical note Performance stated (range, device count, signal strength) applies to unobstructed environments and may vary with building materials, local RF conditions, and device placements.
