It’s on Github: https://github.com/robertklep/name.klep.homekit-controller
But it’s very much a WIP, I don’t even know if it’s able to run at this point.
The easiest way to familiarize yourself with the HomeKit part of the app is to use the hap-controller module from an example script to see if you can get it to pair with a device (or, lacking any HK devices, you can use a Homebridge setup or a standalone device script).
I’ve put some of my debugging/development scripts in a gist: https://gist.github.com/robertklep/cbe45324aa73e1bb7daf0ccb088250db
