Switching from the BACnet library to node-backstack. Added support for Multistate objects. #1218

Closed lpaszcza closed 1 month ago

lpaszcza commented 1 month ago
  1. Switching from the BACnet library to node-backstack.

When querying for the list of objects (OBJECT_LIST) and there is a large number of objects on the controllers (around 100), readProperty returns an incorrect value. Replaced it with the node-bacstack library. https://github.com/fh1ch/node-bacstack

  1. Changing from readProperty to readPropertyMultiple when we querying for name of objects.

The change was made to reduce the number of packets when querying for a large number of objects.

  1. Added support for Multistate objects.

Added Multistate Variable, Multistate Input, Multistate Output.
