So I just got some flic buttons and the flic hub. I noticed that when I start up the hub it can be seen on Homeassistant via the apple homekit integration. However flic does not have any homekit codes anywhere on it.
I posted about this here Flic HomeKit pairing code | Flic Community
but it seems that implemented the apple support using some method that does not require the codes.
Does anyone know a workaround, feels like I just blew through 200$ 
This setup using webhooks has worked pretty well for me. A little complicated, but not too hard to set up.
Rather than making the objects via config, you can make them all using helpers and a single automation to reset anything beginning with flic* (or whatever you name the helpers)
ended up writing my own mqtt integration instead which works way better than this
