(Yes, I've been in a similar place before.)
I think this is different.
Prelude:
I have a function node that is receiving two messages and creating a new message when the two other messages are received.
To help me with seeing what is going on I use the node.status({}) command.
The idea is that when message 1 is received the node indicates that.
Then when message 2 is received, the node also indicates this.
YES! There is a problem with this.
As both messages arrive at the same time (basically speaking) I only see one message.
So to get around this I delayed one of the messages a few seconds.
Given the messages are coming through every 20 seconds, it is not a big deal.
So I set a 3 second delay.
So I'd expect to see (badly worded)
message 1 received. 3 seconds later message 2 received. 17 seconds.
message 1 received. 3 seconds later message 2 received. 17 seconds.
No.
The only way I can get it to do this (with the changes in time understood as being in the equation)
message 1 received. 5 seconds later. message 2 received. 15 seconds.
(repeat)
The messages are complicated but not impossible.
Here are two examples of the messages.
{"payload":{"Who":"TimePi","device":"Modem","Modem":"Online"},"_msgid":"166050d1d44749f4"}
{"payload":{"Who":"TimePi","device":"UpLink","UpLink":"Online"},"_msgid":"570805fe17dd94e5"}
They are sent in together but with a 5 second difference between then.
This is the node:
[{"id":"4bccf388.5f0814","type":"function","z":"c636aa5a.cc34","name":"Make ONE message","func":"let A;\nlet B;\nlet C;\nlet D = context.get(\"D\") || 0;\nlet E = context.get(\"E\") || 0;\nif (msg.topic == \"NEWDAY\")\n{\n return msg;\n}\n\nif (msg.payload.device == \"Modem\")\n{\n //\n // Modem detected.\n //\n// node.warn(\"Modem message arrived\");\n// node.warn(msg.condition);\n context.set(\"Modem\",1)\n context.set(\"Modem_status\",msg.payload.Modem);\n context.set(\"WHO\",msg.payload.Who);\n node.status({ fill: \"green\", text: \"Modem\" });\n}\nif (msg.payload.device == \"UpLink\")\n{\n //\n // UpLink detected.\n //\n// node.warn(\"UpLink message arrived\");\n// node.warn(msg.condition);\n context.set(\"UpLink\",1)\n context.set(\"UpLink_status\",msg.payload.UpLink);\n context.set(\"WHO\",msg.payload.Who);\n node.status({ fill: \"red\", text: \"Uplink\" });\n}\n\n//node.status({});\n\n//if ((context.get(\"Modem\") == 1) && (context.get(\"Uplink\") == 1))\nif (context.get(\"Modem\") == 1)\n{\n //\n if (context.get(\"UpLink\") == 1)\n {\n //\n // both messages received.\n //\n //node.status({fill:\"yellow\",shape:\"dot\",text:\"message\"});\n context.set(\"Modem\",0);\n context.set(\"UpLink\",0);\n A = context.get(\"Modem_status\");\n B = context.get(\"UpLink_status\");\n C = context.get(\"WHO\");\n msg.topic = C;\n //msg.payload = {\"Who\":msg.who,\"Modem\": context.get(\"Modem_status\"), \"Uplink\": context.get(\"UpLink_status\")};\n\n //node.status({});\n \n msg.payload = {\n \"Who\":C,\n \"Modem\": A, \n \"UpLink\": B\n };\n return msg;\n }\n}\n","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":1990,"y":4740,"wires":[["dc8d6eed.9ba1d8","cfb7b905.7a326"]]}]
Why doesn't the node.status work nicely with ONLY a 5 second difference between the two messages being received?
Other stuff:

Thanks in advance.
