/diy/ - Do It Yourself

do you have any idea how (or if) I can control the temperature of an induction hob with an external controller?
my problem is that I own this fucking thing, it's got 7 different settings for heat
1: basically body temperature heat
2: just enough to melt butter
3: will melt butter, turn it black and then into smoke in like 4 seconds
4 - 7: way too hot for cooking up to basically brazing temperatures
in my googling I've pretty much only found people trying to hook a PID to it and mostly being unsuccessful. I don't need anything that fancy, I was thinking a PWM or something like that. do you think this is feasible without rewiring the circuit board or is this a dead end?
