Simple way to add delay to SMH

Hi all, newbie here. I’d been searching for a way to delay arming SMH but all I could find was some next level stuff. I finally figured out a simple way to do it.
Create 2 virtual switches.
One is arm away relay, one is arm away
Smart lighting app, turn arm away relay on when arm away turns off
Power allowance arm away on for 1 minute
Power allowance arm away relay on for one minute
When arm away relay turns on , arm SMH
