If you ask me setting all of this up is a piece of cake. I bought a cheap dongle, Wahoo sensors, downloaded Zwift, and just followed the screen. I was up and running in a few minutes, and I didn't have any knowledge about how it all works. All of the devices and apps inter-operate pretty well with BTLE or ANT+. I have the dongle in my keyboard port and just point the keyboard towards the bike. The biggest problem is that you need the connections before you can get into Zwift, so you can't just go in and find something to ride. When I bypass it I have to exit out and back in to restart the connection process.
