We have a large home; we have an upstairs keypad so we can be alerted if the door is open (so my toddler does not leave the home without our awareness). For 5 years I have had to raise the keypad volume in the day, and mute it manually in the night. It is tedious and we would really like a schedule to be able to mute the keypad after certain hours of the day. Why is this simple function not available? Same with the chime...you can only snooze, but not mute after certain hours of the day!
