Hello, I would like to know how you added a telepresence device and canopy antenna and their respective type roll, type net on NMIS8
I think there are two questions in one here:
To add devices to NMIS you will find the information you need here: Adding and Editing a Device in NMIS8
To add new types of devices and have NMIS collect new and interesting information, we call that device modelling and you can find out more information here:
After that, we have lots of useful documentation on the WIKI.
Opmantek also has services to assist with adding device support.
