Solarthermie: Ertrag ohne Wärmemengenmesser ausrechnen
Viessmann API und Node-Red – Teil 7 – Solarthermie Ertrag weiterlesen
Obwohl die Viessmann API in der Lage ist, den Solarertrag anzuzeigen, ist das entsprechende API Feature heating.solar.power.cumulativeProduced in machem (leider auch in meinem) Fall leer.
Das liegt daran, dass die Solarinstallation mit einem Wärmemengenmesser ausgerüstet sein muss. Dieses Gerät vergleicht die Solar-Vorlauftemperatur mit der Solar-Rücklauftemperatur und misst zusätzlich den Durchfluss. Bei moderneren Wohnungen wird über solche Geräte die Heizkostenabrechnung gemacht.
Wie finde ich nun heraus, wieviel Energie von meinen Solarthermiepanels erzeugt wird wenn ich kein Calorimeter habe?
