Register devices in cloud app

[Tokatubs]

Daniel, installing the app and then logging in to the app the mosaic is there. But is this really online, or do you have to register the device on the network.
The first time i looked at the mosaic from the device everything looked great. But now i see that the values are not updating.
Does this mean that for updates as well the mobil device needs to be registered?

I was of the impression this only meant if you needed push notifficcations.
