Hallo zusammen,
ich bin von meinem Iobroker auf Homeassistant umgezogen.
Einzig die Modbus Integration mit meiner Lambda Wärmepumpe bekomme ich in Homeassistant nicht hin. Konkret geht Raum das Schreiben des Holding Register 102. lesen funktioniert
Anbei die funktionierende Config im Iobroker. Wie bekomme ich diese im HA ?
Du musst das in Home Assistant alles per YAML machen (ist nicht so schön wie im ioBroker). Hier sind einige Beispiele zu finden.
Also erstmal viel lesen und verstehen - ich habe in HA deutlich länger gebraucht als mit ioBroker, bis z.B. mein Wechselrichter integriert war.
Das klingt ja so, als gäbe es schon etwas. Teil doch gerne die Config die Du schon hast.
Danke für die Rückmeldung. Soweit ist mir das klar und ich habe sowohl meine PV als auch meine WP komplett lesbar integriert. Anbei dazu meine modbus.yaml.

unique_id: eu13l_modbus_5152Mein Problem ist es jetzt das Register 102 von EU13L zu schreiben. Bekomme ich im Homeassistant nicht hin. Möglicherweise liegt es daran das ich die Option Write_multiple_Register aktivieren muss. Das ist laut Handbuch der Wärmepumpe erforderlich und im Iobroker konnte ich das auch aktivieren.
Ziel ist eine Automation zu schreiben die mir den Wert des PV Überschusses in das vorgenannte Register schreibt.
Bisher habe ich testweise die folgend Script besucht, klappt aber nicht.
Bin ratlos und Google hilft nicht
sequence:
- service: modbus.write_register
data:
hub: EU13L
unit: 1
address: 102

Jeder Versuch das Register zu schreiben schlägt fehl. Habe es auch erfolglos mit Aktionen => modbus Register.schreiben versucht.
Hallo uhuwald 
,
wenn du vor deinem Code hier im Forum 3x " " zu Beginn und am Ende auch 3x "" eintippst kannst du es in ein Codefeld eingeben und wir können es besser lesen.
Alternativ kannst du diesen Knopf nutzen und dann dazwischen reinkopieren:
Ich habe für dich deinen ersten Beitrag formatiert damit du einen Geschmack dafür bekommst die anderen Beiträge darfst du nachholen 
Danke für den Hinweis. Gern ändere ich die Formatierung in der Hoffnung anderen die Hilfe zu erleichtern.
Ergänzend noch ein Hinweis aus der Doku der Wärmpumpe.
Beim IObroker konnte ich dazu das „Häkchen“ gem. Screenshot setzten.
Nur wie bekomme ich es im HA umgesetzt.
Blockzitat
Es können eine Reihe von Parameter und Istwerte von der Steuerzentrale der Wärmepumpe ausgelesen
bzw. beschrieben werden. Die Steuerzentrale fungiert dabei als Slave.
Die Zeit eines Kommunikationstimeout beträgt 1min. Erfolgt in dieser Zeit kein Abruf wird die
Verbindung geschlossen und muss neu aufgebaut werden.
Die Lesefunktion erfolgt über die Modbus Funktionscode 0x03 (read multipel holding register)
Die Schreibfunktion erfolgt über die Modbusfunktionscode 0x10 (write multiple writing register)``
Da sind aber ein paar Anführungszeichen falsch im Value Template. Du benutzt gerade doppelt hochkomma '' statt Anführungszeichen ". Teste mal:
- action: modbus.write_register
data:
hub: eu13l
address: 102
value:
- '{{ states("sensor.fems_gridactivepower") | int | bitwise_and(65535) }}'
Eventuell war wirklich nur das Template falsch. Eine Value-Liste zu übergeben im Yaml ist schonmal richtig:
(write_register) A single value or an array of 16-bit values. Single value will call modbus function code 0x06. Array will call modbus function code 0x10.
Das passt ja zu
Die Schreibfunktion erfolgt über die Modbusfunktionscode 0x10 (write multiple writing register)
Offen wäre aber noch der Datentyp, was die andere Seite erwartet. Also int oder unsigned int (also vorzeichenlos) und die Länge des Datentyps (16, 32, …)
Und die Reihenfolge der Bytes ist auch wichtig. Also Little Endian oder Big Endian.
Values might need reverse ordering. E.g., to set 0x0004 you might need to set
[4,0], this depend on the byte order of your CPU
65535 wäre ja uint16. Was hattest Du da in ioBroker konfiguriert?
Dankeschön. Funktioniert
Tatsächlich waren es die Anführungszeichen. Allerdings hatte ich das gleiche nochmals in der Modbus.yaml beim modbus Name. Beim lesen ist das nicht aufgefallen, da der Name nur außerhalb der modbus.yaml ( also im Script) benötigt wird.
Eine Frage noch, laut Hanbuch der Wörmepumpe müsste ich ein
Signed 16 bit (Big Endian) nehmen. Was müsste ich dafür benutzen?
Also anstatt 65535 für uint16 im Falle Signed Int
