In my set up it is an array - I think....
["0,0,1","0,0,0","0,0,0","0,0,0","0,0,0","0,0,20","0,0,0","0,0,0","0,0,0"]
So I think that is addressed. I don't know if deleting the context is a good idea. IT is ongoing and can be used at any time.
This is part of the code where the messages are received and shown to me.

Event_occurence is the incoming message and the MQTT OUT node on the right is what goes to the LED strip - kinda.
if you want an array then
let rgb = msg.payload.split(",");
if(!msg.as_is){
let stored = flow.get("rgb[" + rgb[1] + "]") || `${rgb[0]},${rgb[1]},0,0,0`;
stored = stored.split(",");
msg.payload = `${rgb[0]},${rgb[1]},${Number(rgb[2]) || stored[2]},${Number(rgb[3]) || stored[3]},${Number(rgb[4]) || stored[4]}`;
}
flow.set("rgb[" + rgb[1] + "]", msg.payload);
return msg;
but an object would be better. your choice.
I started with a mess and went to an array as I have used them for other things and it is kind of how I think. It is an array of states of each of the LEDs.
Yeah, an object may be better, but I don't think I will gain anything at this stage of the game.
Way too much code written now.
I am just wanting to work out a way to allow the R G B values to be altered individually by messages arriving at different times and changing the displayed colour depending on the type of messages.
The || option looks like that is more the one as it allows something that && didn't that I only realised after starting off down the && trail.
