Installation

Before installing, VOLTTRON should be installed and running. Its virtual environment should be active. Information on how to install of the VOLTTRON platform can be found here.

1. If it is not already, install the VOLTTRON Platform Driver Agent:

   vctl install volttron-platform-driver --vip-identity platform.driver
   

2. Install the BACnetProxy Agent. An example configuration can be found here

   vctl install volttron-bacnet-proxy --agent-config <path to bacnet proxy agent configuration file> --vip-identity platform.bacnet_proxy
   

3. Install the VOLTTRON BACnet Driver Library:

   poetry add --directory $VOLTTRON_HOME volttron-lib-bacnet-driver
   

4. Store device and registry files for the BACnet device to the Platform Driver configuration store:

   • Create a config directory and navigate to it:

     mkdir config
     cd config
     

   • Create a file called device_name.config; it should contain a JSON object that specifies the configuration of your BACnet driver. An example of such a file is provided at the root of this project; the example file is named 'bacnet.config'. The following JSON is an example of a bacnet.config:

     {
         "driver_config": {"device_address": "123.45.67.890",
                           "device_id": 123456},
         "driver_type": "bacnet",
         "registry_config":"config://bacnet.csv",
         "interval": 15,
         "timezone": "US/Pacific"
     }
     

   • Create another file called device_name.csv; it should contain all the points on the device that you want published to Volttron. An example of such a CSV file is provided at the root of this project; the example CSV file is named 'bacnet.csv'. The following CSV file is an example:

     Point Name,Volttron Point Name,Units,Unit Details,BACnet Object Type,Property,Writable,Index,Notes
     12345a/Field Bus.12345A CHILLER.AHU-COIL-CHWR-T,12345a/Field Bus.12345A CHILLER.AHU-COIL-CHWR-T,degreesFahrenheit,-50.00 to 250.00,analogInput,presentValue,FALSE,3000741,,Primary CHW Return Temp
     

   • Add the bacnet driver config and bacnet csv file to the Platform Driver configuration store:

     vctl config store platform.driver bacnet.csv bacnet.csv --csv
     vctl config store platform.driver devices/bacnet bacnet.config
     

5. Observe Data

   To see data being published to the bus, install a Listener Agent:

   vctl install volttron-listener --start
   

   Once installed, you should see the data being published by viewing the Volttron logs file that was created in step 2. To watch the logs, open a separate terminal and run the following command:

   tail -f <path to folder containing volttron.log>/volttron.log
