The best way around this is to provide us with a copy of raw output from the developer's console (ctrl + shift + i) element viewer and store it in code </> blocks for us to look at.
Given how you've presented it means there could be different types of formatting that needs to be "filtered" out in order to retrieve the correct variables you are looking for.
Assuming that the variables you have are exactly as we see them, here's the regex to get you started:
Just replace 1: with 2: and so on
if you create a new BACnet-Data-Source your local device IP (old system settings / BACnet local devices: 192.168.100.105:47808) should be the same as the Mango-Server has:
If you create a new BACnet data point it should look like:
where the "Device instance number" is the given Device ID, here 5.
If all BACnet-Devices are in the same IP-Range you don't need a BBMD.
Be carful if you scan a large BACnet-Network with many devices and objects. It can take a long time and need server-resources. Better is to scan one ID.
