Zigbee switch for completely powering off the panel

My PIR sensors beeps when move detected even though the alarm is not armed. Unfortunately it's not possible to disable the beep as far I know.

That's why I'm thinking to completely switch off the panel by using a Zigbee switch between the power supply and the panel. 

Has someone did this before? Is it bad for the panel to be switched off and on multiple times a day?
