Using the Speaker Companion smart app with the SmartThings Android client there is the option to trigger only during a specified time interval
It is not possible to set a start time before 10:00am - all times before this are rejected by the client however they are entered.
With the Classic app this problem does not occur - I can set up an interval starting before 10:00am
I am worried as I now see the Classic app is to be no longer supported
