Envisalink (EVL-3) with Ademco/Honeywell (Vista 20p) VS AD2USB

Hey everyone, I recently noticed that there is now a plugin for my Vista 20p panel using the Envisalink module.

I actually have an Envisalink connected to the panel, as well as an AD2USB module that is connected to the panel and used for integration with Vera.

What I wanted to know is there an advantage to switching to the Envisalink plugin over the existing AD2USB integration? I actually recently added an expansion module to my panel, and plan on moving around some of the zones. If the Envisalink would let me not have to go through the setup of all of the virtual relay settings again…that would be helpful!

I dug around online, and found a lot of information with the DSC panels, but not too much on the Ademco/Honeywell integration.

Any help/insight would be appreciated.

Thanks!
