Easy BACnet · BACnet field reference

How do I use Easy BACnet to get a points list off a building?

Short answer

Connect your phone to the same network as the building controls, open Easy BACnet, tap Scan for Devices, wait for the scan to finish, then tap Export Results. The app reads every point on every device it found and hands you an email with a CSV attached. Tap View Results instead if you want to look at the devices and points on the phone first.

Before you start

Step 1 — Scan

Tap Scan for Devices. The app broadcasts a BACnet Who-Is and listens for replies. It keeps re-broadcasting for up to about forty-five seconds, because Wi-Fi access points drop broadcast packets routinely and one shot is not reliable. A counter shows how many devices have answered so far; let it run to the end.

When it finishes you get a one-line summary, for example Scan complete — found 6 device(s), and two buttons: View Results and Export Results.

If the summary warns about unconfigured devices or duplicate Device IDs, that is worth telling whoever looks after the system. Both are commissioning mistakes that will cause trouble for any integrator later. See BACnet Device IDs explained.

Step 2 — Look at what it found (optional)

Tap View Results. Each device shows its name, Device ID and IP address. Tap a device and the app reads its full object list — on a big controller this can take a minute, because it asks for the points one at a time on purpose, which is the only way that works with every controller ever made.

Tap a point to see its Present Value, Units, Status and Description, with a Refresh button for a fresh read. On points that can be commanded you also see Commanded At and Falls Back To — whether something is currently overriding the point, and at what priority. That one screen answers "why is this damper stuck open" more often than anything else in the app.

Step 3 — Export

Tap Export Results (from the home screen after a scan). The app now reads every point on every device: names, present values, units and status. A progress box shows which device it is on. Do not walk out of Wi-Fi range while it runs.

When it finishes, your email app opens with a message and a CSV attached. You choose who it goes to. The app never sends anything itself and has no idea who your integrator is.

The CSV columns are: Device ID, Device Name, Device IP, Object Type, Object Number, Point Name, Present Value, Units, Status. That is exactly what someone asking for a points list needs — see a vendor asked for my BACnet information.
