How to switch sonoff with tasmota at Islamic prayer


I have sonoff pow flashed with tasmota

I would like to switch on my pow at Islamic prayer times by javascript note-red via MQTT

I created a google calendar with all the islamic prayer timings for my city and I’ve been with IFTTT but there are some delay (15 minutes )

Does anyone has an idea how to do that?
