You should try the app. IFTTT web version was fairly complicated, the app pretty simple even if a bit limited. I haven’t used it for a while, it was based on a nice and simple interface, it gave you some choices to mix together, one of my favorite was “if - snow - then - send an alert”. Basically you have to choose what should have triggered the alert. Very intuitive.
Or “turn of the wi-fi when - out of home”. Set the location of your home and you’re good to go.
For more complex actions it was a bit more complex, but the UI was icon based and very intuitive ( Ok, sometime icons wher not that clear, but fortunately they added labels).
Problem is that as user you can choose among a list of pre-prepared recipes, long and extensive of course, but not exhaustive .
Good luck with your project
