Ok, so you have two Plugin files (
D_DENONAVR889.xml and
D_Acquos.xml) that have been "auto" built for you by Vera, based upon it's IR Database.
In turn, Vera has used these Plugin files to build Vera Devices, specifically
_TV and
_Receiver. These Device stubs are meant to represent the physical "TV" and "Receiver". The "_" is just there to remind you to rename them, and place them into Rooms that make sense.
It's this Physical Device that has a setting to "know" which IR Device it needs to use. If you have the Puck, and the SQBlaster Plugin, then you'd set the TV and Receiver devices to use the SQBlaster as the "IR" Transmitter.
Now you have the Device stubs in Vera, and you've let Vera know to use the SQBlaster for their IR Control, you can use "Advanced" Scenes (the Advanced Tab) to perform IR Actions against those devices.
The primary use-case for doing all this "dance" is to do things like "Power Off" from Vera, as a part of a larger "Goodnight" type scene where various devices around the house are shutdown. Obviously, the Advanced Scenes in MiOS lets you do any of the IR actions that the specific Plugin exposes ("ChannelUp", "ChannelDown", "VolumeUp", etc, etc) but it's far more likely that you'd do that directly between SQRemote and SQBlaster.
That said, you could use it to turn on TV's (etc) whilst you're on vacation, to make the house look more lived in.
and yes, there's a reason that it's being more tightly integrated... to avoid all these discrete setup steps
