Timer functionality on panel

[tpanajott]

Is your feature request related to a problem? Please describe. It would be nice to be able to set a timer on the panel and make it beep until confirm when it finishes. This would come in Andy when cooking.

Describe the solution you'd like A button for "start timer" where a user can enter the number or minutes, perhaps with a +/-1 minute and +/-10 minute button. When the timer runs out send a notification to Home Assistant that the timer has run out so that the user can implement notifications on the smart phone if so desired.

Describe alternatives you've considered N/A
