Heizungssteuerung Wärmepumpe Fußbodenheizung
Tag werden die Laufzeiten der Heizung gelogt. Die Relais der Heizkreise werden von einem m8-1-wire-slave geschaltet, der gleichzeitig den Hauptprozessor überwachen soll. Manuelle Eingaben sind über eine Ferbedienung möglich. Das Programm ist inzwischen so komplex, dass es von Dritten wohl nur
