* Motor error checking. Timeout overall (if regulation fails or stuck). Timeout movement (motor is tunring but no change in poti value detected). Move right direction. * Motor error checking. Timeout overall (if regulation fails or stuck). Timeout movement (motor is tunring but no change in poti value detected). Move right direction.
* Relais switching (selection and muting) * Hardware: motorentstörkondensatoren einbauen direkt an motor. 47nF + zu - und zwei 10nF + zu case und - zu case
* MQTT topics * PI Optimieren. aktuell overshoot
* Implement knob menu structure
