It seems to me that there are some exceptions being thrown silently somewhere which is very frustrating.
When you set up V2 it should have given you some default superbridge patterns, but here are the defaults just in case that is not working:
SuperBridge Out
house/devices/{DeviceName}/{State}
SuperBridge In
house/devices/{DeviceName}/{State}/set
SuperBridge Action Groups
house/scenes/{ActionGroup}/execute
The plugin will substitute those placeholders for your device names, and subscribe accordingly, so if you have debugging enabled you should see a subscription for every device.
I know this is testing your patience, but if one of you guys that are experiencing problems could try setting these patterns, I'd appreciate it!
