The Attune BACnet Server allows users to present data collected by Attune to their BMS via BACnet. The device comes preconfigured with a unique API Key that will help the device securely retrieve a configurable set of data from the Attune Cloud and expose that data to the BMS. The BMS will be able to discover the BACnet Server and the different data points exposed. Contact Attune Support if you need to modify the set of points exposed to one your Attune BACnet Servers. You will need to provide support with the Device Serial Number.

The Attune BACnet Server comes with 2 Ethernet ports that are completely isolated from each other: one for the BACnet network and one to connect to the Attune Cloud.

To properly wire and power the device:

  • Plug in an Ethernet cable connected to the BACnet network into the ETH1 - LAN port. Plug in the cable from the ETH1 - LAN port to your computer in order to initially setup the network settings of the device.

  • Plug in an Ethernet cable with Internet access into the ETH2 - WAN port

  • Plug in the power supply connector at the top of the device as show in the figure below

ETH1 is the port through which you can configure the network settings of the device. The device can be accessed using the default IP address The network settings have to be modified to allow the device to communicate with your BACnet network.

To access the device via ETH1, enter the IP address into a computer browser that can communicate with the device. You should see a login page. The username is admin is the password is written on the back sticker of the device, as shown below.

Once Logged in, click on Diagnostic at the bottom of the left menu. Then go to Setup > Network Settings

You can enter on this page all the configuration details for the BACnet network.

ETH2 is configured to received network settings via DHCP but that can be edited on the ETH2 tab on the same page.

The Routing tab should not be modified and should show ETH2 as the Routing Interface.

To make sure the device is receiving data from the Cloud, navigate on the left menu to View > Data Arrays > DA_AI and you will see a table that should be refreshed every minute with the latest data. Make sure the Data Age is less than 1 minute, which will show that the BACnet Server is able to retrieve the data continuously.

You can now try to discover the device and its points using your BMS. The device's BACnet ID is 389002.
