Hier das was du vermutlich haben möchtest. Den Inject musst du ersetzen, sodass dort der Wert deiner Zisterne einfließt

   

Code:

[{"id":"a1777d62.0927","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"75e584c7.32e99c","type":"function","z":"a1777d62.0927","name":"","func":"flow.set('wert_fuellstand',Number(msg.payload))\nreturn msg;","outputs":0,"noerr":0,"x":515,"y":180,"wires":[],"l":false},{"id":"2e2b760c.c98ffa","type":"rbe","z":"a1777d62.0927","name":"","func":"rbe","gap":"","start":"","inout":"out","property":"payload","x":455,"y":180,"wires":[["75e584c7.32e99c"]],"l":false},{"id":"8ae4c3a2.c9544","type":"http in","z":"a1777d62.0927","name":"/Zisterne","url":"/Zisterne","method":"get","upload":false,"swaggerDoc":"","x":200,"y":120,"wires":[["68da0598.c2eadc"]]},{"id":"68da0598.c2eadc","type":"function","z":"a1777d62.0927","name":"","func":"var o=\n        {\n        Fuellstand:Number(flow.get('wert_fuellstand'))\n        };\nmsg.payload  = JSON.stringify(o);\nreturn msg;","outputs":1,"noerr":0,"x":315,"y":120,"wires":[["bdff46bf.c5e3b8"]],"l":false},{"id":"bdff46bf.c5e3b8","type":"http response","z":"a1777d62.0927","name":"HTTP-Response","statusCode":"200","headers":{"content-type":"text/html"},"x":375,"y":120,"wires":[],"l":false},{"id":"a721deff.6674","type":"inject","z":"a1777d62.0927","name":"Test Wert 56","topic":"","payload":"56","payloadType":"num","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":230,"y":180,"wires":[["2e2b760c.c98ffa"]]}]

Im Gekko machst du daraus eine HTML-Abfrage. Diese erstellst du unter Einstellung.

   


Statusabfrage des Füllstandes via JSON
Typ:                                  Get- INPUT 
Read Int:                            0
Request On:                       [IP NodeRed]:1880/Zisterne
Request Off / Parameter:     JSON@Fuellstand



Zu guter Letzt basteln wir uns daraus noch eine Analyse



   



Viel Erfolg
