FAQs

What happens if I choose "Any Port: 0.0.0.0" for the Local Endpoint?

If you select Any Port: 0.0.0.0, the BACnet Gateway will automatically select the network interface with the highest priority based on the RAK gateway's configuration. This ensures that the gateway uses the most appropriate IP address for the current connection. It is particularly useful in scenarios with multiple WAN connections or failover setups, enabling seamless switching between available interfaces.

What happens if I specify a specific Local Endpoint?

If you select a particular network interface for the Local Endpoint, the BACnet Gateway will bind to the IP address assigned to that network interface. If the selected interface becomes disconnected or unavailable, the BMS will lose communication with the BACnet Gateway until the connection is restored, or another valid interface is configured.

Can I replace a sensor without modifying the BMS integration logic?

Yes, you can replace a sensor without modifying the BMS integration logic by following these steps:

1. Navigate to the Equipment page in the BACnet Gateway.
2. Select the device you want to replace and click Export to download its configuration and details into a CSV file.
3. Update the Device’s Authentication Information:
   • Open the exported CSV file.
   • Update the device authentication details, such as DevEUI, AppKey, NwkSKey, DevAddr, and AppSKey to match the new sensor's information.
4. Re-import the Updated Device Information:
   • After updating the authentication information, re-import the updated CSV file into the BACnet Gateway.
   • The system will automatically map the new device and apply the existing settings and data points.

How do I configure the BACnet Gateway for MQTT integration?

To configure MQTT integration, follow these steps:

1. Go to the Configuration page of the BACnet Gateway.
2. Enable the MQTT settings option.
3. Configure the MQTT Server:
   • Enter the MQTT server address (e.g., broker.hivemq.com or your local MQTT broker address).
   • Specify the MQTT port (typically 1883 for non-secure connections or 8883 for secure connections).
4. (Optional) Set additional settings based on your MQTT broker configuration.
5. Click Save Changes to apply the MQTT configuration.
6. After configuration, you can subscribe to the relevant MQTT topics to receive messages from the broker and process them accordingly.

Once the configuration is complete, the BACnet Gateway will communicate with the MQTT broker, enabling real-time data exchange with third-party applications.
