Dale:

I also have a dual Butterfly setup, and to get Flarm on both, I actually had to independently wire the Flarm core (formerly known as the brick) to both Butterfly vario units independently. I was not able to get the master vario to pass Flarm traffic data to the second unit. Perhaps this has been fixed in the most recent software update?

Marc:

It seems that you cannot get the Butterfly vario traffic page to identify Flarm traffic and let you select individual targets to display distances, climb rates, etc. Marc, will this be feature be coming in a future update? It would be nice to have the Butterfly vario units obsolete the need for a separate Flarm display.
