It seems to handle a use case I was looking for.
I have a cheap xiaomi aqara hub that is homekit compatible, and I want to exports its data. Sadly usually the use case is to connect a non homekit iot to a homekit server from an apple device with homebridge. Here their HomeKit adapter use a lib called hap-controller-node that seems to be a homekit server. I will have to try this.
