HM-800 Wechselrichter mit Ahoy DTU

hfichtinger · 16. Mai 2024 um 10:28

Ich habe besagen Wechselrichter und eine Ahoy DTU. Damit kann man etwaige Fehlermeldungen als Json-String erhalten.
Ich hab mir die Mühe gemacht, dafür ein Profil mit allen dokumentierten Meldungen zu erstellen.
Das ganze als JSON String

Falls es jemand brauchen kann.

Hallo Helmut,

auch ich habe einen HM-800 WR, den ich mit AhoyDTU abfrage per MQTT. Wie machst Du das? Und wie schaut es genauer mit der Meldungsvariable aus. Ich habe aktuell nur die Inverter-Temperatur und die Leistungsdaten aktuell und Summe drin.

Danke und viele Grüße
Kevin

Hallo Kevin
Ich bekomme von der Ahoy einige Topics rüber. Im Screenshot alle die „MQTTT Server Gerät“ heißen.

Die Einstellungen auf meiner DTU sehen folgendermaßen aus:

Ansonsten habe ich keine speziellen Einstellungen gemacht.
Hier noch eine Liste der Topics, die es bei mir gibt:

Die Ausgabe bzw. die Aufbereitung der Alarmmeldungen hab ich so gemacht:

<?php
$html_id=38209;
$alarm_id = array ( 44624, 
                    47304, 
                    38749, 
                    11887, 
                    38705, 
                    45612, 
                    47396, 
                    36459, 
                    40664, 
                    45717);

$html="";
$html=$html."<meta name=\"viewport\"><html><head><script type=\"application/javascript\" src=\"./preview/wwx.js\"></script></head>";
$html = $html."<table class=\"wwx\" border=\"1\" style=\"width:100%\">";    
$html = $html."<tr>";
$html = $html."<thead class=\"".getvalue(25118)."\"><th><center>Zeitpunkt</center></th></th><th><center>Meldung</center></th></thead>";
$html = $html."</tr>";

foreach($alarm_id as $alarm)
{
    $offset=date("I",GetValue(IPS_GetVariableIDByName("Start",$alarm)))+1;
    $code = GetValueFormatted(IPS_GetVariableIDByName("Code",$alarm));
    $start = GetValue(IPS_GetVariableIDByName("Start",$alarm));
    $start=$start+($offset*60*60);
    if (date("d.m.Y",time())==date("d.m.Y",$start))
    {
        $ende = GetValue(IPS_GetVariableIDByName("Ende",$alarm));
        $ende=$ende+($offset*60*60);
        $html=$html."<tr>";
        $html=$html."<td><center>".date("d.m.Y H:i:s",$start)."</center></td>";
        //$html=$html."<td><center>".date("d.m.Y H:i:s",$ende)."</center></td>";
        $html=$html."<td><center>".$code."</center></td>";
        $html=$html."</tr>";
    }
}
$html=$html."</table>";
setvalue($html_id,$html);

Das Profil für den Code findest du oben im ersten Beitrag.

Besten Dank. Ich schaue mal, ob ich deine Infos benutzen kann und der WR auch was ausspukt.

Viele Grüße
Kevin

Der Wechselrichter spuckt gar nix aus ;-). Die Werte kommen von der Ahoy DTU. Ist der WR korrekt mit der DTU verbunden und siehst du bei Live etwas?

Bei mir zieht gerade ein Gewitter auf

Du kannst auch links oben auf den Namen (bei mir Gartenhaus) klicken, dann kommen Werte

Und wenn du auf „Active Power Control“ klickst, kannst den WR damit auch umstellen.

Wenn ein Alarm vorhanden ist, öffnet sich bei einem Klick auf Alarms das Fenster.
