Einbindung Heliotherm Sole-WP per ModBus

Verfasst: 1. Dez 2020 13:02

Liebes Forum,

anbei das letzte Projekt für dieses Jahr.
Ich will meine Heliotherm Sole WP per ModBus in Openhab einbinden.
Das ganze soll dann auch gesteuert werden durch die PV-Anlage bei Stromüberschuss.

Bin mir nicht sicher wie die reads und writes funzen und dann in Openhab aufgebaut sind.
Folgende Doku habe ich von Heliotherm
https://www.loxwiki.eu/download/attachm ... 000&api=v2

Kann mir wer ein Beispiel für read und write geben und wie das Thing auszusehen hat?

Danke und BG

So heute hatte ich endlich mal wieder Zeit. Mit Hilfe des Beitrages viewtopic.php?t=3535 der anderen Forumsteilnehmer funzt das Auslesen der Heliotherm schonmal.

Anbei schon mal die .things.

Am Ende der Things ist ein Beispiel für write. Write traue ich mich noch nicht. Kann einer mal drauf schauen ob das Beispiel zum Screenshot des Herstellers passt?

Bedienungsanleitung sagt zum Schreib-Zugriff:
Schreibzugriff
Über den Schreibzugriff kann die Wärmepumpe gesteuert werden. Etwas weiter hinten befindet sich die

Liste der zu schreibenden Register. Diese können mit dem Funktionscode 06 (Write Single Register) be-
schrieben oder mit dem Funktionscode 03 (Reas Holding Registers) gelesen werden.

Bei einem Verbindungsabbruch muss der Modbus-Server / Master einen Re-Connect mit dem RCG X
initialisieren. Die Register sollten prinzipiell zyklisch, aber nicht schneller als in einem 5 Sekunden- Intervall
beschrieben werden.

falls das noch einer liest und mir weiterhelfen kann:

Habe die WP nun eingebunden und lesen funzt. Nun will ich folgendes umsetzen:
Bild_2020-12-30_194854.png
Reicht es eine Rule zu erstellen, und in die folgenden beiden Register zu schreiben 117=1 und 125=1000 Watt als Beispiel und dies mit einer Rule in Abhängigkeit zur aktuellen PV-Leistung zu bringen? Weiß jemand ob ich auch checken muss, dass die Rule für Warmwasser nur einmal pro Tag ausgeführt wird oder regelt das die Wärmepumpe?

Sobald ich dann per Rule:

Code: Alles auswählen

rule "WP PV Anforderung AN"
when 
  Item WP_PV_Anforderung changed from OFF to ON 
  then 
    //if (Tag_Nacht.state==ON  && (now.getHourOfDay() >= 16 && now.getHourOfDay() <= 20 ))
    {
      Modbus_Waermepumpe_PV_Anf.sendCommand(1)
      //createTimer(now.plusSeconds(5), [| logInfo("Timer", "My Timer!")])
      Modbus_Waermepumpe_Leistungsaufnahmevorgabe.sendCommand(900)
    }
end
die PV Anforderung per Switch schalte, erscheint die Fehlermeldung im log.

Warum schaltet die Wärmepumpe den Wert zurück auf "0"?

Die Länge der Bridge hat nicht gepasst. Man muss von 100 bis 134 und somit 35 angeben. Das war die Lösung.
