I just updated most of my homebridge installs. I was particularly excited by the idea of the activities grouped under a single accessory. However, after upgrading and deleting the persist file, as well as, removing the homebridge hub and re-adding to HomeKit. The activities still show up as accessories.
This is how they have always shown for me since 0.2.
But if you move any activity to a room in homekit, all the other activities on the same hub follow. This saves time if you have many activities on a hub.
