Thanks for looking!

10A is kind of limiting for a kettle. Even my cheapo kettle takes 12.5A. And it's not clear if that amazon controller has PID functionality. I could be wrong but I would expect that a simple set point with a dead band probably won't work especially well with a kettle. When I do it manually I find I have to shut off the heating element before I get to the temperature or else it overshoots.
