I'm confused as to how the flow you posted relates to the question you asked.  
The flow has 3 inputs ( 2 alexa and one MQTT which looks like a switch)  
so where does `day` and `brightness` come into your flow?

But if you want to direct `message 1` and `message 2` to different places use a `switch` node  
as one payload is a number you can set a switch to `is of type` `number`

Could you be a bit more descriptive? Even lookng at your flow, I don't know whart you want. Explain the issue and use the type/names of nodes you are using in your flow

Ok, when you are posting a flow for others to look at you should assume that any nodes - other than the standard flows - are not installed by others asnd you should provice the full node names so they won't have to spend their time figuring out what you have not provided.

You should also try to create the issue with a minimum number of nodes (use inject nodes to inject data from a sensor etc) and provide the platform, os, os release and the NR and node.js versions

What are you trying to do with the message afterwards?

Do you need an output message every time a new message either type comes in?  
Or only when a new mesage1 or message2 comes in?

You can use a Join node to combine two message payloads with different topics into a single message containing key/value pairs.

Node-red msgs are javascript objects, so I'm not sure that what you are asking is even relevant, since the order of properies in an object are not guaranteed. Perhaps you are trying to force a sqaure peg into a round hole... can you provide some _formatted_ json examples of one msg that is ok, compared to another that is not what you want?

As Colin mentions, if you are trying to place objects into an specific indexes in a payload array, it would be safer to use named properties in a single key/value object (which the `join` node will do for you). Just set the `msg.topic` for each sensor to be the "key" to use as the property name -- then it doesn't matter what order the msgs arrive.
