Changes to just get Devices with given DIDs

[DerKarussellbremser]

For Sure, there is a littlebit to do. An option to enable and disable this feature. An easy method to get the DIDs from the devices with all names so you don't need to guess the right one.

Thanks for this great idea, but without these features I cannot merge this, because everyone would have to add all his DIDs:

To-Do

• Option to enable and disable the DID Feature
• option to choose if you include or exclude the given DIDs

At least check if the list is empty or not existing at all and then everything must work as before.
