What i was meaning is does the new SkyQ remote also feature IR as well as BT. I then realised that it must do, as otherwise it would not be able to control the TV volume/power etc.
The volume control would be for a TV. It doesn't need the Sky Q box to be on.
Whilst the new remotes do have BT, I've been assured by someone who should know that the new Sky Q boxes can also be controlled by an existing Sky+ HD remote. Since the Sky+ HD remotes are IR only, please take this to mean that you should be able to control your Sky Q box with such a remote.
Now this doesn't mean that you'll be able to use all the functions on the Sky Q remote, if any, to control the Sky Q box with an IR sender. That I don't know.
If you were to keep a Sky+ HD remote to hand you should be able to do most of the 'normal' things on a Sky Q box.
At this time I can't be sure that the Sky+ app will work with a Sky Q box either. There are already a few buttons I would love to have replicated in the Sky+ app (e.g. coloured buttons) as there are functions that aren't being supported by the app. This could become more of an issue in the future.
If all the buttons could be replicated, then this would also mean that there would be less of a call to have an IR sender IMHO.
Of course I did get a clear impression that Sky are wishing to encourage people to have a Sky Q Mini connected directly to each TV rather than using a HDMI splitters. I realise that many members might not like this but it was the impression I got.
