So, i got a JSON string like this:
{ "Attribute1":"Test","Value1":"Testvalue" }
It got like 20 Attributes with corresponding values. The String is being loaded and saved from and to a file, which isn´t a problem, but how can i easily change 1 Value in the existing String, coming from another source like MQTT.
I tried it using the change node and Flow messages, which works but i guess there might be a more efficient way to do that, maybe with a function node?
I´ll have to use this like a hundred times so it would be great to have only a few nodes to be configured.
Thanks in advance
