Hello guys, in my NODE-RED flow, I have 4 MQTT In nodes receiving data every 10 seconds from a Python script via the server. Now, I want to integrate the 4 inputs from the MQTT nodes into a function and output the average every 10 seconds. I don't have a solution on how to precisely calculate the average value in the end.
Hi and welcome
You could join the four mqtt nodes manually using a join node, then do your calculation. Create a single message from separate streams of messages : Node-RED
Or possibly feed your mqtt nodes into the smooth node which can do an average. node-red-node-smooth (node) - Node-RED
p.s. I have moved the category to general, as this is not about developing a node.
