Anbindung Solakon One mit Fhem

rippi46 · 12 Dezember 2025, 13:23:58

Hallo ,

habe seit ein paar Tagen einen Solakon One Batteriespeicher mit itegriertem Wechselrichter.
Die Einrichtung mit der Solakon App auf dem Handy hat relativ einfach und problemlos funktioniert.
Jetzt wollte ich aber ähnlich wie beim Deye Wechselrichter (Deye SUN-M200G4-EU-Q0) auch die Werte in fhem erfassen und grafisch darstellen.

Da es eine HA-Integration schon gibt ich aber nicht zweierlei Systeme betreiben wollte und ich in fhem noch nichts gefunden hatte,
habe ich versucht schon einmal die meisten Werte auszulesen. Falls es jemand gebrauchen kann ist hier meine RAW-Definition.

Hallo rippi,

vielen Dank für Teilen deines Ansatzes in FHEM.
Ich habe das gleiche vor und melde mich falls ich Ergänzungen habe.

Viele Grüße,
Jan

Hallo,
ein Zwischenstand von mir:
Leider tauchen bei mir keine Readings auf. Ich musste ohnehin die Definition anpassen, nach der Adresse noch ein "-reading" hinzu. Ein anderes Gerät läuft mit nahezu identischer Definition problemlos.
Hier mal meine Test-Def, natürlich mit korrekter IP-Adresse:

Code Auswählen

define SolakonOne ModbusAttr 1 60 192.168.xx.yy:502 TCP
attr SolakonOne enableControlSet 1
attr SolakonOne event-min-interval .*:600
attr SolakonOne event-on-change-reading .*
attr SolakonOne group Elektrik
attr SolakonOne icon solar
attr SolakonOne maxTimeoutsToReconnect 3
attr SolakonOne obj-h30016-len 16
attr SolakonOne obj-h30016-reading SerialNumber
attr SolakonOne obj-h30016-unpack (a16)
attr SolakonOne obj-h30032-len 16
attr SolakonOne obj-h30032-reading Manufacturer
attr SolakonOne obj-h30032-unpack (a16)
attr SolakonOne obj-h36001-reading master_version
attr SolakonOne obj-h36001-unpack n
attr SolakonOne room Energie

Seltsam ist, dass wenn ich nach Modbusobjekten scannen lasse, dann kommen passende Daten an. Die angelegten "obj" Attribute führen aber wohl nicht zum Anlegen von Readings

Grüße,
Jan

Nach einem umfangreichen Update aller FHEM-Module läuft jetzt deine Konfiguration auch bei mir.
Hatte ich mir schon fast gedacht, nachdem deine Attr - Einträge so unterschiedlich aussahen.
Also nochmals danke für deinen Post oben

das sind die meisten Werte die man vom SolakonOne bekommt.

PS: Steuern hbe ich noch nicht versucht!!!
