LinknLink RD1100+ is a compact Zigbee 3.0 USB dongle for Home Assistant. It uses a Silicon Labs EFR32MG13 Zigbee radio and a standard USB-A 2.0 interface to connect Zigbee devices without occupying unnecessary space around your gateway.
Local Zigbee control for Home Assistant
Use RD1100+ as the Zigbee coordinator for local smart-home automations with ZHA (Zigbee Home Automation). For Zigbee2MQTT, verify the installed firmware and current coordinator support before deployment.
How to set up RD1100+
- Connect the dongle: Insert RD1100+ into an available USB-A port on your Home Assistant gateway.
- Add ZHA: In Home Assistant, open Settings > Devices & Services > Add Integration, then search for ZHA.
- Select the detected adapter: Choose the serial device detected by Home Assistant. The device path can vary by host and installation; do not assume a fixed path.
- Create the Zigbee network: Follow the ZHA prompts to create the network, assign a room, and finish setup.
- Pair devices: Open Configure > Add Device in ZHA and reset the Zigbee device you want to pair.
Multiple Zigbee devices can be paired through Home Assistant after the coordinator is configured.
