Yes, my integration uses their cloud-based API.
I recently added Hub 2 support, including supporting the sensors built in to the hub. This is an upgrade over the original Hub Mini, but you should also be able to run both SwitchBot hubs at the same time if you want to. It'll be seamless to my integration, and I assume their cloud will just sort it out.
I haven't found much public info about their local device support, but I will take a look at it when they publish info to see if it could be supported.
