Medication Reminder Light

My 95 y/o mother is starting to forget to take her medications.

I have designed a “lamp” with 120 LED’s that will turn on at 07:30 and 17:00. (Using a D1mini)
I currently have preset 1 to turn on a red light, and preset 2 with a (T=0).

I want to add a button to this so that the light will not go off until the button is pressed, but will still come on at the next time cycle.

I would like to know what D1mini pin I need to use, and what I need to set the WLED configuration at to do this.

Thank you

I tested with GPIO5

Thank you.
This worked perfectly.
Now to design a better looking 3d printable “lamp”
