Electrical scheme

The electrical scheme include the circuit to control NON PWM Fan (3 Pin).

If you already have a PWM Fan (4 Pin) ignore this part and connect the fan pwm pin directly to the GPIO D1

Config JSON example

Setpoint configuration file.

The algorithm calculate the fan speed between the setpoint with a linear function.
