smart window thermostat Answered
circuit to open window at night when it is cooler outside than in.
Close it when hotter outside in morn.
Probably add something to prevent it from opening and closing several times in the eve and morn with random fluctuations.
Prefer 2 thermostats, 1 outside, one in, rather than a timer.
I've a vague recollection of a circuit with 2 potentiometers, one on the motor, one on the control panel, such that turning the control pot will activate the motor until its pot is at the same position as ctrl pot.. Could a circuit something like this control my window? But most thermostats are on/off, not continuous variable.
It would be simple to do a switch logic thing like: “IF thermo ‘I’ is above 70 AND thermo ‘O’ is below 70, THEN OPEN “ but that only works at 1 temp.
