If you already have Homebridge running, you can add it to HomeKit Controller in HASS and the devices in Homebridge will appear in HASS. Then you can use Home Assistant Device Bridge to bring many (not all yet, but a good amount of them) into HE. This can allow you to expose devices that work with a Homebridge plug-in, back to HE by way of HA.
Several ways to do things. Options are good.
