I started with easy lesson 5 today. It has a new chord progression, always 3 or 4 fingers on some mellow (minor and diminished) chords. And because it takes a while to reposition the left hand, I need to pedal this. Best pedaling is, if you don't hear that you are pedaling. But still there are no abrupt changes in the chord progression. Meaning, pedal down as late as possible (to make RH melody not mushy / depends also on the specific notes), but early enough to give your hand time to reposition.
And I can't repeat enough: when the hand goes down (in my case LH), the pedal goes up.
That's it: Easy to know, but early-late beginner level to master.
Edit: if you want to master it in early beginner state, you should start as bloody, lovely or total beginner already.
Blues Piano for Beginners Lesson 13 "The St. James Infirmary Lesson" is also a good place to start with pedaling. Christian doesn't talk about it, nor does he demand it, but there are some quite good places for pedaling.
