Alert - time window?

Feature Requests

One feature I miss with the Alert component is the feature to time restrain the alert.

An alert is “quick to notice any unusual and potentially dangerous or difficult circumstances; vigilant.”

But some alert can be delayed to appropriate times, like if your sensor batteries go below a certain level. An alert is appropriate, but not at 03:00 in the night. This could be postponed to 9:00.

I would suggest an Alarm time parameter for a valid time interval. Default 24-7 or

time: "09:00:00–21:00:00"
or
time: 
  - "09:00:00–10:00:00"
   -"18:30:00–20:15:00"
