Charging switch before wake up

Configuration

Hi
I want to switch charging switch some time before my alarm on android device will be run
i know how to do it except :smiley:
I don’t know how to create automatization which will run on condition
i have from android device timestamp which is showing time in millisecond, and I want to take time now
and add to it for example 1800000milisecound which is 30 minutes
for example
time now +18000000 > sensor.sm_g988b_next_alarm_2 —> timestamp from this

can anyone help me how to create it ?
