Motivation
Über die Zeit haben sich neue Erkenntnisse herauskristallisiert. Diese sollen hier erfasst und abgewogen werden. Da das NodeMCU Modul nur über eine beschränkte Anzahl von Ein- und Ausgängen verfügt, bietet es sich an, über mögliche Buslösungen nachzudenken. So sollen möglichst alle Sensoren via I2C-Bus betrieben werden.
Mit dem Einsatz eines sehr einfachen Temperaturreglers (2-Punkt Regler) konnten auch schon ein paar Eigenschaften der Regelstrecke gefunden werden. So ist zum Beispiel die Eisbildung beim Kühlmitteleintritt ein Problem, das gelöst werden soll.
