Peel tries to be an entertainment center hub, so once you set it up it wants to download listings and allow you to just click on "show me this show" and it takes care of the rest. Which is a severe pain in the tuckus for those of us who don't even HAVE a TV subscription and just want to use it to control IR devices.
It is probably turning itself on to download listing updates, trying to find things that you may be interested in watching based on your setup, etc.
I disabled it and just got another remote app.
