PS4 On Homebridge
These are instructions to create a series of buttons within the Apple Home app that control PS4 power and open/close any app you want.
Begin by installing
Node.jsif you haven't already. Their website has up-to-date versions and installation instructions for your OS.
For macOS I use Homebrew to install packages. If you're a developer (or an aspiring one), I highly recommend using it. Via homebrew, installing node is as simple as
brew install node.
