Hier ist ein „Flow“, um die Werte eines Photovoltaik-Inverters von Kostal per Node-Red auszulesen und zus\u00e4tzlich als MQTT-Nachrichten zu versenden. <\/p>\n\n\n\n

Der Hintergrund ist, dass die Anlage nicht per SNMP oder \u00e4hnlich g\u00e4ngigen Verfahren auszulesen war, sondern nur \u00fcber eine Webseite die Werte anzeigte. Zwar gibt es eine Software, aber die hat meine W\u00fcnsche nicht wirklich erf\u00fcllt.<\/p>\n\n\n\n

Mit diesem Flow ist es m\u00f6glich, die aktuelle Leistung einer PV-Anlage aktiv alle z.B. 20 Sekunden abzufragen, und die gelieferten Werte als Diagramm im Dashboard darzustellen. <\/p>\n\n\n\n

\"Node-Red
Node-Red Flow<\/figcaption><\/figure>\n\n\n\n

Zur Langzeitvisualisierung versende ich die Werte zus\u00e4tzlich an ein weiteres System (Zabbix). Das sieht dann so aus:<\/p>\n\n\n\n

Hier ist ein „Flow“, um die Werte eines Photovoltaik-Inverters von Kostal per Node-Red auszulesen und zus\u00e4tzlich als MQTT-Nachrichten zu versenden. Der Hintergrund ist, dass die Anlage nicht per SNMP oder \u00e4hnlich g\u00e4ngigen Verfahren auszulesen war, sondern nur \u00fcber eine Webseite die Werte anzeigte. Zwar gibt es eine Software, aber die hat meine W\u00fcnsche nicht wirklich … <\/p>\n
