I just posted this in another thread, so you can read it there, but the V2 hub actually delivered very little local processing. Again, details in the other post.
Just to be sure, you’re aware that there’s actually almost no local operation with the smartthings V2 hub, right? It’s still basically a cloud-based architecture.
The only things that will run without a connection to the SmartThings cloud on the V2 hub is the official smart lighting feature (and then only with some device type handlers) and some parts of smart home monitor. For example, routines do not run locally, the Phillips hue and harmony integrations do not run locally, notifications do not run locally, no custom code run locally. Also, the SmartThings mobile app on your phone cannot talk to the hub without going through the cloud, even if your local Wi-Fi is still up. So you won’t be able to do anything with the mobile app if your Internet access is down.

And I don’t believe it changed anything with regard to secondary Z wave controllers.
