Stuck splitting messages

General
1

I am using bigtimer and looking at output #2.

example:

{"payload":1,"reference":"DAYTIME:SUNRISE:SUNSET:744","topic":"status","state":"ON Auto","time":"05hrs 21mins","name":"Day Start/End","start":372,"end":1065,"dusk":1090,"dawn":347,"solarNoon":718,"sunrise":372,"sunset":1065,"night":1148,"nightEnd":289,"now":744,"timer":0,"duration":321,"onOverride":-1,"offOverride":-1,"stamp":1554603861685,"_msgid":"44e46be.5464d94","_event":"node:2c23f48.2b3238c"}

I am wanting to cut this message up to get the many sub-pieces.
So I have a sunrise message. A sunset message. A dawn, dusk etc etc.

split doesn't seem to work.
Neither does switch. At least the way I have it.
Using switch I get the entire message sent out each output.
(or something like that. Actually I am probably wrong in saying it.)

But at the end of the day it isn't working and I am stuck how to do it.

Your string looks like json. Try the json node to turn it into javascript object and then further process it.

I've kind of nutted it out in the mean time.

I tried putting the json node in to the flow, but I still couldn't "spit" it.

(input from BigTimer's #2 output)
Ultimately this is what I did.
Messy, but it works:

(Edit)

This is one example of some flow I tried which didn't work.
You can see the json node and the split and switch.
Didn't work.

There are multiple ways to do this, 1 version:

[{"id":"5549e92f.f9fb98","type":"inject","z":"e6817f81.7d7f8","name":"","topic":"","payload":"{\"reference\":\"DAYTIME:SUNRISE:SUNSET:744\",\"topic\":\"status\",\"state\":\"ON Auto\",\"time\":\"05hrs 21mins\",\"name\":\"Day Start/End\",\"start\":372,\"end\":1065,\"dusk\":1090,\"dawn\":347,\"solarNoon\":718,\"sunrise\":372,\"sunset\":1065,\"night\":1148,\"nightEnd\":289,\"now\":744,\"timer\":0,\"duration\":321,\"onOverride\":-1,\"offOverride\":-1,\"stamp\":1554603861685,\"_msgid\":\"44e46be.5464d94\",\"_event\":\"node:2c23f48.2b3238c\"}","payloadType":"json","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":250,"y":380,"wires":[["7c7004e3.37ef9c"]]},{"id":"224db7f8.a81eb8","type":"debug","z":"e6817f81.7d7f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":550,"y":320,"wires":[]},{"id":"7c7004e3.37ef9c","type":"function","z":"e6817f81.7d7f8","name":"","func":"m = msg.payload\n\nout1 = {payload:m.start}\nout2 = {payload:m.end}\nout3 = {payload:m.dusk}\nout4 = {payload:m.dawn}\n\nreturn [out1,out2,out3,out4];","outputs":4,"noerr":0,"x":390,"y":380,"wires":[["224db7f8.a81eb8"],["4af0225f.34b4dc"],["9464e2cf.62509"],["9775c6ec.01b5d8"]]},{"id":"4af0225f.34b4dc","type":"debug","z":"e6817f81.7d7f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":550,"y":360,"wires":[]},{"id":"9464e2cf.62509","type":"debug","z":"e6817f81.7d7f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":550,"y":400,"wires":[]},{"id":"9775c6ec.01b5d8","type":"debug","z":"e6817f81.7d7f8","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":550,"y":440,"wires":[]}]

didnt check the output of the jsonata, was incorrect, removed it.

Thanks.

I'll look at it soon - I hope.

Just found another problem with one of my flows.

Why make it so complicated?

Just access the properties directly:

Yeah the "problem" is that I still need to split the messages.

But it with a function node to separate them or with debug nodes with filtering in them to which part of the message is shown.

As I am wanting to set context/flow/global (not sure yet which) either n function nodes are needed or one which splits them and (though not in the flow I posted) set the context values.

8

A change node would work as well.

9

Again: True. But there would need to be one for each value I wanted to use.

10

Not true! Multiple lines!

11

How can a change node set contexts?

I'll look into it too. But I am not sure that part is still in the scope of what is actually the desired goal.

Ok.

Mia Culpa.

I don't use the change node that often.

12

I almost only use change nodes and very few function nodes.
