Seems that the problem was that influxdb always configures the field type the first time a series is accessed.
I thought that the value was something like a "variant" and would eat anything I throw at it. So when I altered the data types in the flow, the db refused to save.
A drop and re create solved the problem.
You're welcome!
I've used node red like you are doing for some times and it works well. Since around 1-2 years I'm using home assistant as controller, and node red for the logic in automations.
Home assistant makes life much easier, as it for example takes care of filling data into influxdb automatically
I reply to myself, I succeeded to make it work.
The \n was missing in the payload before sending it back to the gateway.
This took me months to see this...
Works like a charm now, I just need to implement the inclusion feature in NodeRED.
This seems to evaluate to true/undefined every time, effectively resetting the array:
var global_individual_data=global.get("global_invidual_data");
if (global_individual_data===undefined) {
msg.kein_array_vorhanden="true"
global_individual_data=[];
}
even though it's later set with
global.set("global_individual_data",global_individual_data);
