4. Instrucciones de funcionamiento

4.1. Coordinator Mode (Default)

The ZBDongle-E is pre-flashed with coordinator firmware. In this mode, it acts as the central hub for your ZigBee network, managing all connected ZigBee devices. Once connected to your smart home platform, you can begin pairing ZigBee end devices and routers to build your network.

• Ensure your smart home software (e.g., Home Assistant with ZHA or Zigbee2MQTT) is configured to recognize the dongle's serial port.
• Initiate the device pairing process within your smart home platform.
• Follow the pairing instructions for your specific ZigBee end devices or routers to add them to the network.

4.2. Modo enrutador

The Dongle Plus can also be flashed with router firmware. In router mode, the dongle extends the range of your existing ZigBee network by relaying signals between the coordinator and other devices. This is particularly useful for large homes or areas with weak ZigBee signals.

• To use the dongle as a router, you will need to flash it with appropriate router firmware. This process typically involves using specific flashing tools and firmware files. Detailed guides are available on community forums (e.g., Home Assistant, Zigbee2MQTT communities).
• After flashing, plug the dongle into a USB power source (e.g., a USB wall adapter or a powered USB hub) at a strategic location within your ZigBee network to extend coverage.
• The router will automatically join your existing ZigBee network if it's in pairing mode, or you may need to initiate pairing from your coordinator.
