I would like that when I put the hydrome into deep sleep, that the hydrome sends a message directly

Turning off the function makes no sense.

The sugar method is used in the device. However, only the reference method is documented.

The explanation of what exactly you can do with it is missing.

The hostname that was set as the Hydrom name should also be updated in the Fritz!Box.

In the attached screenshot 1.3.4 has been updated to 1.3.4.1. Unfortunately, you can't see that when the success message is displayed. Here at least "nothing" should be displayed instead of the old fw. Version.

To track the progress of the update, it would be helpful to see a progress bar.
