Eric,
A couple of things that I noticed is that node-bacnet wants node 0.12.0 or newer, whereas the node on Conduit is stuck at 0.10.48 due to the fact that node stopped supporting the armV5 architecture after that release.
This is a node module, so are you trying to require it in a function node? I don’t believe that anything will show up in the Node-RED pallet.
