It was the second time in almost 2 month, that a alarm is repeating. The first time restarting Homey helps. The second time after restarting Homey the alarm from 2 day ago is repeating.
Now I've switch off the AlarmeringDroid in the setting menu.
I noticed myself too. I think it has to do with the scanner going offline for some time (those damn windowsupdates seem impossible to hold back in Windows 10).
