Crazy-to-BikeSeit gestern haben wir ein seltsames <a href="https://fediworld.de/tags/Kommunikationsproblem" rel="nofollow noopener" target="_blank">#Kommunikationsproblem</a> zwischen unserer <a href="https://fediworld.de/tags/Wallbox" rel="nofollow noopener" target="_blank">#Wallbox</a> <a href="https://fediworld.de/tags/Tinkerforge" rel="nofollow noopener" target="_blank">#Tinkerforge</a> <a href="https://fediworld.de/tags/Warp" rel="nofollow noopener" target="_blank">#Warp</a> 3 und dem <a href="https://fediworld.de/tags/Goodwe" rel="nofollow noopener" target="_blank">#Goodwe</a> <a href="https://fediworld.de/tags/Wechselrichter" rel="nofollow noopener" target="_blank">#Wechselrichter</a>. Die Wallbox zeigt dann für die <a href="https://fediworld.de/tags/Stromzähler" rel="nofollow noopener" target="_blank">#Stromzähler</a> "GoodWe Smartmeter" (Netzanschluss) und "Pylontech Force-H3" (der am WR angeschlossene Speicher), deren Daten beide vom Goodwe WR geliefert werden, nichts mehr an. Dann funktioniert wenig überraschend das <a href="https://fediworld.de/tags/PV" rel="nofollow noopener" target="_blank">#PV</a> <a href="https://fediworld.de/tags/Überschlussladen" rel="nofollow noopener" target="_blank">#Überschlussladen</a> nicht mehr. Steht das Laden auf "nur PV", hört der Ladevorgang folglich auf und man steht am nächsten Tag weiterhin mit leerem <a href="https://fediworld.de/tags/Akku" rel="nofollow noopener" target="_blank">#Akku</a> da, wenn man es nicht rechtzeitig bemerkt. Das Kuriose: Im Router ist der Goodwe weiterhin online. Die Daten werden auch sowohl an das <a href="https://fediworld.de/tags/Semsportal" rel="nofollow noopener" target="_blank">#Semsportal</a> von Goodwe als auch an <a href="https://fediworld.de/tags/Homeassistant" rel="nofollow noopener" target="_blank">#Homeassistant</a> geliefert bzw. sind von diesen abrufbar. Die Anbindung / Kommunikation der Warp3 und HA an den WR ist jeweils über <a href="https://fediworld.de/tags/Modbus" rel="nofollow noopener" target="_blank">#Modbus</a> <a href="https://fediworld.de/tags/TCP" rel="nofollow noopener" target="_blank">#TCP</a>. Lösen konnte ich das beide Male durch Drücken des "Reconnect" Buttons am <a href="https://fediworld.de/tags/WifiModul" rel="nofollow noopener" target="_blank">#WifiModul</a> des Goodwe. Nachdem sich dieses neu mit dem <a href="https://fediworld.de/tags/WLAN" rel="nofollow noopener" target="_blank">#WLAN</a> verbunden hat, zeigt auch die Warp3 die Daten wieder an. Was mich dabei eben irritiert, dass nur die Warp3 keine Daten mehr bekommt / abrufen kann. Es ist also offensichtlich kein generelles Problem des Wifi Moduls vom Goodwe. Kann sich da jemand einen Reim drauf machen oder hat eine Lösungsidee. So ist das ziemlicher Mist.
