Not only does it wake it from sleep, but it also turns it on if it was shutdown.

That being said, I had the same issue as the previous comment when initially pairing my Controller to the Machine (I got the 2TB Machine but had a Controller from when they initially launched). I had to do my setup with an Xbox controller instead and after running the initial updates, it paired without issues and I’ve been able to easily use it on the Machine and my desktop PC.
