            volttron create agent with discoverable BACnet points
            Asked 2021-May-13 at 14:48

            I was curious with VOLTTRON agent development if an agent could be used to expose discoverable BACnet points to a building automation system.

            For example, BAC0 that also uses bacpypes under the hood like VOLTTRON I can create a really simple BACnet app (shown below) and discover my BAC0 app (and points) via BACnet to the building automation system.

            I have an odd use case not to control or acquire data (I think typical VOLTTRON use case) but only to "expose" a few read only AV BACnet points (integers that represent the count of people in particular HVAC zones from some other system counting people) to the building automation system.

            Sorry another vague question but would there be any examples to look at if anyone has done this with an agent development? I'm curious if some BAC0 code could just run in an agent if the BACnet proxy has not been installed via typical VOLTTON development. Any tips/help greatly appreciated.

            I get the feeling that the question might still be slight vague/open-ended (- possibly open to interpretation), but if you're talking about exposing some custom (/additional?) objects via BACnet, then to be compliant with a BACnet 'client' - such as the BMS, you'd have to include those objects within the Device's/device-object's 'Object-List' property, so that the BACnet clients would recognise it's availability.

            (One day someone could try to be clever - for security reasons and support the Read-Property service for objects without having them available/advertised within the Object-List but 1) it would only work if they were also developing the client too - with knowledge of this, and 2) it would not be compliant with the standard.)

            Volttron, noSegmentationSupported for BACnet devices
            Asked 2021-Apr-16 at 12:58

            Hellow,

            Hope you are doing great.

            I am reading data from AHUs but while fetching the list of objects it gives an error: segmentationNotSupported. On sending WhoIsIAm (bacnet_scan.py), I get this response:

            Just because your client can (supposedly) support segmentation for "Both" directions - transmit & receive, the server/device/AHU doesn't.

            So in order to read the full object-list, you have to fallback to looping thru the Object-List array - one element at a time.

            Element/array-index 0 of the array (- the first element), contains the count of the number of data elements; for each element that you want to read - including the first one/element, you have to specify the target/desired element/index that you wish to read.

            volttron BACnet scan with virtual box ubuntu
            Asked 2020-Dec-11 at 16:38

            I am running ubuntu 18.04 LTS on virtual box. Is it possible to scan for real (non virtual) BACnet devices on a LAN through the virtual box VM?

            How would I set the BACpypes.ini?

            My Windows 10 machine if I do a ipconfig/all this doesn't work with the BACpypes.ini when run bacnet_scan.py on my VM

            Or this IP address of my Windows 10 machine.

            Both IP addresses implemented onto the BACpypes.ini will throw an: OSError: [Errno 99] Cannot assign requested address

            If I do an ifconfig of my ubuntu VM this doesnt appear to error anything on the bacnet_scan.py but none of my BACnet devices come up either. Any tips greatly appreciated...

            Currently your VM is set up with a host-only connection. Host-only connection does what it says on the tin: you're only able to communicate with the host. To contact with the LAN around the host, set the VM's networking mode to "NAT" (This makes your VM routable through the host machine). Then, look up your VM's IP again and try that.
