I haven't seen scenes, homebridge basically ports the devices over. Then inside the homekit compatible app on your iDevice you create rooms and zones to group the devices. Homekit is smart enough to then make logical groups. For example, create a room called great room, then put three lights in it. You can tell Siri to turn on the great room lights and they all come on, likewise, Siri, turn off the great room lights works. Turn on the indoor lights also works for all rooms in the indoor zone.
You can also setup scenes in the iDevice app. The examples in the Eve app are Good Morning, Good night, I'm home and I'm leaving.
I found I needed the Insteon+ app to initially setup my Homebridge device, then I use Eve and iDevices to control and manage them.
