Pitching an idea here: my current wife tends to “overcorrect” when she thinks the house is too hot or too cold. This is typically by selecting a setpoint for the temperature that is irrationally, warmer or colder than her desired setpoint. This break down tends to be attributable to her transient emotional reasoning that it will get hotter or colder. “faster” if she overcompensates for the set point.
I, being a dutiful husband and tinkerer, have devised a plan to have large, smash ball, brightly colored blue and red buttons that she can smash repeatedly when she is displeased with the temperature.
I can measure of the force with which she hates them with a load sensor, and obviously the number of times she hates them can easily be measured.
Granted, the actual temperature setpoint is an unknown, so the process variable will really just be an absence of smashing buttons. I’ve considered a profanity detector as well.
