Hi, Node-Red v3.1.0 I have a simple 'edit function node' which collects values from global variables and formats a message with those values. I want this function to run once a minute so have put a 'inject node' in front of it. To monitor whats happening, I've put a 'edit debug node' on the outp…

Thanks Steve, the extra debug nodes identified the issue. Taking the speed counters out of being in-line has resolved the issue. [image]

[image] ChrisG: What I get is the inject node starts the activity, and the debug node 'sees' the message, then sees it again, and again, and so on. At the rate of one every second. Hello Chris, Ofcourse the Function node will see every message you send it .. now i gather that you want to do …

I suspect your problem may be here [image] "Every 1m" is in italics, indicating that's the node's name, not how frequently it is set to trigger. [image] Mind you, I'm not familiar with this node [image] And there may well be a problem here too [image]

Thanks Guys, UnborN, you are right re the function node reacting to every message, but I was hoping the trigger sending one message per minute would mean the function node would do one message per minute. I'll look more at the context you mentioned. jbudd, you are right, with the inject node name…

Here is the json for the issue:- [{"id":"4b211f23c08b43f4","type":"tab","label":"Flow 5","disabled":false,"info":"","env":},{"id":"af5483388c10dfb5","type":"function","z":"4b211f23c08b43f4","name":"Combine 6 global variables into one payload","func":"msg.payload = \n\n{\n\n "solarPvId" …

Add debug nodes to the outputs of the inject and the speed nodes. Do they also show the same frequency of messages? Also, your flow is corrupt as you have not wrapped it in a code fence. Canned Text: In order to make code readable and usable it is necessary to surround your code with three backti…

Ah Steve, Here is the flow with a 2nd speed node and ticks:- [{"id":"4b211f23c08b43f4","type":"tab","label":"Flow 5","disabled":false,"info":"","env":[]},{"id":"af5483388c10dfb5","type":"function","z":"4b211f23c08b43f4","name":"Combine 6 global variables into one payload","func":"msg.payload = \n…

[image] ChrisG: the extra debug nodes identified the issue. For the future, the moral is that any time you have unexpected results, then use debug nodes to work backwards through the flow to find out which node is actually malfunctioning.

Function node sends multiple messages instead of one

Malfunctioning is in the eye of the beholder.
For you it was functioning badly. But yes, you are right, 'not as expected' is better.
