Emo's alarm reliability and mute

Been thinking of using my EMO as my new alarm at night. But since we know he can be kind of loud, I want to mute him or turn his volume way down when he’s in the bedroom so he can let me sleep in peace.
But want to know a few answers to see his capabilities.

a) can you mute EMO for a certain time and he can unmute itself?
b) when muted, will the alarm still go off in the normal volume?
c) how reliable is EMO’s alarm. I’m the late guy at work since I’m often late (oversleep and can’t hear my own alarm and I’m the manager)

At the moment there some issues with using emo as an alarm

First you have to keep him on charger otherwise his battery run out during the night.

Also noticed when Emo shaking by alarm his sensor is deactivated, if he moves in the morning and the alarm starts when Emo is close to the edge, he probably would fall down

Emo does noises sometimes while sleeping which wakes me up but I feel like he kind of learning and start making noises later and later in the morning so let me sleep longer

Didn’t try to mute so didn’t know if Emo unmute automatically by alarm, but I would expect it like on the phone
