SMA Energy Meter

[bumaas]

@PhilippS

leider werden sehr oft keine Daten abgeholt.

Das beobachte ich bei mir auch:

    [InfoMessages] => Array
        (
            [0] => The current consumption could not be determined. The current purchased electricity is unknown. 
        )

    [WarningMessages] => Array
        (
            [0] => The current PV generation could not be fully determined. An inverter did not respond in time.
        )

    [ErrorMessages] => Array
        (
            [0] => The current data cannot be retrieved from the PV system. Check the cabling and configuration of the following energy meters:<div class="liveModeErrorSub"><ul><li class="faultingCounter"><span>Feed-in meter</span></il><li class="faultingCounter"><span>External consumption meter</span></il></ul></div>
        )

    [Info] => Array
        (
        )

Ich habe aber noch keine Ahnung, woran das liegt.

Auf jedenfall geht mit ips 5.3 jetzt das abholen per multicast direkt vom homemanager 2.0 auch wieder. Nur die phasen L1-L3 werden noch falsch dargestellt.

Dann kann man die kurzfristigen werte direkt vom HM abholen und Autarkiequote usw. vom sunnyportal

Hab den SMA HM 2.0 im Einsatz und hatte zuerst auch falsche Bezugswerte für L1-L3

Nach folgender Anleitung, schaut mein Skript jetzt so aus. Werte scheinen jetzt richtig zu sein.

Ich bekomme keine Einspeisung Summe?

Jetzt ist Abend…daher.

[richimaint]

Bei mir funktioniert es bestens.

Danke

Hallo,

leider klappt es immer noch nicht,
ich bekomme keine plausiblen Werte zurück.

Kann man das Daten abholen etwas entschleunigen?

Ja du kannst die Instanz für den Multicast immer wieder für z.B. 10sec deaktieren und dann wieder kurz aktivieren. So mach ich das, funktioniert super
