Time controlled switches

Hi everyboy.
Sorry my english, and if it isn’t the place to write my topic.
I use a 2 ch. WIFI Smart Switches for opening two differents electric doors from the phone, and it works perfectly.
My problem is that I only want the switches work from 9.00 to 17.00 L-V.
How can I do?
Thank you.

Use detach/de-couple mode, and set scenes to trigger relay with external switches, assigning affective periods.
