Control your mac display with HomeBridge. Currently this only works if you are running homebridge on a mac, and will only control the display of that specific mac. I made this for personal use, since I use a Mac mini to control my homebridge as well as a HTPC, so it's convenient to be able to turn the display on and off from my phone.

• Install homebridge: npm install -g homebridge
• Install homebridge-mac-display: npm install -g homebridge-mac-display
• Update configuration file

All you have to do is add a new accessory under the DisplaySwitch name:

"accessories": [
  {
    "accessory": "DisplaySwitch",
    "name": "My Mac HomeBridge Host"
  }
]
