Geht leider nicht. Aber genau das hatte ich gesucht.
Muss mal schauen ob ich mit homeassistant ein Dummyzähler bauen und ob ich diesen von außen auch abgreifen kann.

Falls Du im homeassistant nodeRED installieren magst, wäre hier die Lösung:

Ganz links wird ein http-Endpoint namens "heizer" definiert. Wenn der angesprochen wird, geht's im nächsten an den Shelly, der den Status als String zurückliefert, der dann mit der JSON-Node zu einem JS-Objekt konvertiert wird. In diesem wird nun in der Change-Node relays[0].ison abgefragt und je nach status in den einen oder andern Fall verzweigt. Die letzte Node schließt den http-request ab.

Code: Alles auswählen

Einen kleinen Stolperstein gibt's noch: In einer Standard-Installation lauscht nodeRED auf Port 1880, also ist der URL http://192.168.x.x:1880/heizer. Musst mal kucken ob das im homeassistent auch so ist und ob die Eingabevalidierung in der openWB das verträgt.

Oder Du machst's gleich in MQTT. Dazu erst den Shelly auf den Broker der openWB pubishen lassen:

Und dann ist das hier der Flow:

Konfigurieren musst Du nur den MQTT-Broker und die richtigen Topics in den beiden MQTT-Nodes.

Habe es mit Node-RED wie du beschrieben hast gelöst (HTTP).

Mit MQTT hat kurz die OpenWB den Wert angezeigt ist dann aber wieder auf Null zurückgesprungen.
Ich werde mich mal mit NodeRed beschäftigen.

Besten Dank Gero für deine super Zuarbeit!
