There is described a building automation system comprising a communication component, a processor, and an output component. The communication component scans the building automation system to discover devices, and the processor generates a visual code for a particular field device. The visual code identifies a uniform resource locator directed to a virtual node hosting environment of the building automation system associated with the field device. The output component produces the visual code at a physical material for exhibition in proximity to the field device. Thereafter, the hosting environment receives a status request, associated with the uniform resource locator, for the field device from a mobile device. The hosting environment generates point information associated with the field device based on information collected from the field device in response to receiving the status request. The communication component sends the point information to the mobile device.
