Owen,
If the premium version is available at the meeting, will the TIU and Remote have to be upgraded as well as the WIU firmware?
The Premium app requires only an upgrade to the TIU code. The remote will also get an update, however, it's only required if you use the remote. The WIU firmware stays at version 1.1, where it's been for quite some time.
We'll have the latest available upgrades at the meeting.
