Just FYI if anyone ever runs across this post regarding Automate 2 Pulse hub, I got it to work by deleting the location in the Pulse 2 app so that I had no locations. This prompted the app to set up a new hub and location since I had no locations. When I stepped through the process of adding a new location and hub it finally got the hub to work. For some reason the first time I went through this process it did not work properly and it looks like the hub was not completely provisioned properly. Removing the location was the only way to reset things and add a hub, even though the original location I setup had no hubs.
