This is a pretty simple setup:
  Siri is used to control Homebridge using the HomeKit protocol.  
  Homebridge has a module named Homebridge-ssh that allows you to run commands over ssh.  
  There is a shell script on an OpenWrt box to enable, disable, and check the status of a MAC Address block in the FORWARD table. 


1. Install node on your platform. I went with 8.9 for no specific reason other than I initially had issues with 10 that probably weren't related..
2. Install homebridge and homebridge-ssh.  You should probably also put hombridge-config-ui-x on there too... I used the unsafe-perm parameter after getting a significant number of errors:
  sudo -i npm install -g homebridge --unsafe-perm
  sudo -i npm install -g homebridge-ssh --unsafe-perm

# NOTE: To build on CircleCI, you must take care to keep the `find`
