So, I want to use Pulseway to control my pc from a distance when I play music... But I can't do it, I dunno why, can anyone help me? I followed the steps, but it says that the remote control feature is not available... I do not know why?

Just thought it might work after watching Linuse's video, but still nothing 

For remote control to work you may need to enable it on the system you installed Pulsway on.

Load up your Pulseway manager, click the System tab, then click the Remote Control tab and click to enable

Hope this helps
