Alert only on for 15 seconds

[biosmanager]

Describe the bug The alert function with a custom timeout ends after 15 seconds, however the last state is restored after the specified seconds. Internally, this uses Hue's v2 breathe functionality, however, this also seems to be limited to 15 seconds.

Expected behavior Internally, this could loop the breathe function after 15 seconds.

Is this expected behaviour at this point or can this be fixed?
