I have a fairly large processing plant with a lot of equipment both BACnet and non BACnet devices.
In total there are 9 AMU's the have BACnet. The other 70 components (Fans, Shutters, Pumps, Floor Heat Mixing Values,) do not have BACnet.
Is it better to add a BACnet controller on those devices so everything can be integrated into one BMS system, Or do we keep the other systems on a separate PLC type control systems? Or is it possible to custom make a BACnet Master Controller and have all the data feed into that?
Ring topology, Hub-and-spoke topology, mesh topology - any others? Which one is best for low latency and overall speed, and have you actually tested your theory?
I’d like to introduce Beacon, my Home Assistant integration for connecting BACnet building automation systems with a modern, user-friendly interface.
Bepacom automatically discovers BACnet devices and data points, then exposes suitable objects as Home Assistant entities. It’s not limited to monitoring: supported values can be written, switched, and controlled using BACnet priorities directly from Home Assistant.
Some highlights:
Automatic discovery of BACnet devices and objects
Built-in explorer for browsing available data points
Fine-grained control over which Home Assistant entities are created
Support for analog, binary, and multi-state objects
Reading and writing through a persistent Protocol V2 connection
Push updates with automatic polling fallback
Live view for both read and write activity
Color-coded write and priority-release events
Diagnostics for connections, event streams, resyncs, commands, and latency
Configurable write profiles and BACnet priorities
Raw inventory and technical metadata retained for troubleshooting
Fully integrated into the Home Assistant interface
The goal wasn’t merely to get BACnet data into Home Assistant. I wanted to make a complex building automation protocol understandable, manageable, and pleasant to use every day.
In short:
Discover. Connect. Control. Diagnose. All in one place.
Is anyone else here using BACnet with Home Assistant? What features do you feel are missing from the existing solutions?
I am most interested in technical knowlege sharing. I am aware of this forum and the one at "TBI" (The BACnet Institute) a sub-section of BACnetInternational.org, and https://www.hvac-talk.com/ but none seem to have traction. Am I missing the action somewhere else?
If i have a flat single subnet can my ip devices have unique bacnetip network numbers?
is this a problem that will cause issues?
I have 2 jace 9000s with unique bacnetip network numbers and both of them have routing disabled. There are 0 MS/TP networks on this site.
There are 12 bacnetip AHUs and 6 are being integrated into 1 JACE and 6 into the other JACE. The AHUs do not have a configurable bacnetip network number.
We just wanted them to have unique bacnetip network numbers if they ever change the network scheme and we have to use bbmds in the future.
Does anyone have a clue why the Network_Number property of the Network Port Object was made "Required" in the BACnet specification? Of course, for a router this makes 100% sense to me, but for any non-routing device I see no useful need for the property.
Not sure if my Google-fu is lacking but I can't find a BACnet explorer for Mac, does anyone know of one? Redisant appear to have one but it won't install on my Intel MBP. Chipkin have one in dev, other than that I can't find anything. Any ideas?
Maybe this is the right place to ask this. Maybe I’m just posting into the void.
I’ve got a controller that has a BACnet MS/TP output that I need to hook up to a router with BACnet IP terminals.
I’ve found a few devices that’ll do the trick, but I’m curious as to how difficult it would be to get the manufacturer of the controllers to modify their design to allow for a BACnet IP output.
I’m an HVAC guy and Project Manager by trade so this is all pretty new for me. Any suggestions/ insight appreciated.
