Hi everyone,

I am trying to upload data from Node-red to my Thingspeak channel. I am using 'node-red-contrib-thingspeak42' node to send multiple sensor values. But it uploads single value per field after every 15 seconds. Is there a way I can send an array instead of a single value to my channel.

The above node aggregates the data but it overwrites the stored value if a new value comes in. I would like to send all the values the node receives in that 15 second duration and upload it and plot it in the channel.

Any help would be much appreciated.
