Splitting A Message Payload In Node Red In this simple project we will look at splitting a simple message payload, and then display the data in a text box and on gauges on a dashboard. the payload consists of a simple string containing temperature and humidity readings separated by a ampersand (&). For example, the split node can turn a single message whose payload is an array, into a message sequence where each message has a payload corresponding to one of the array elements.
Splitting A Message Payload In Node Red In 'streaming mode', this node will split a message and send each complete segment. if there is a partial segment at the end, the node will hold on to it and prepend it to the next message that is received. When returning an array of messages from a function node you need to make it a 2d array to return all the messages from a single output. e.g. this is because the first level of array is the port to output on, and i'm guessing you only have 1 output port configured so all the others are being discarded. For multiple connection points a switch node would allow you to break up those messages to discrete outputs. to have multiple discrete outputs on a function, the setup tab in the function node will allow you to add outputs. then each message needs to be defined in the function. The split node can be used to split the message into one message per line. it can be followed by the nodes needed to operate on the individual lines of text, followed by a join node to recombine them back into a single block of text.

At my power meter i installed a tasmota device which is sending mqtt messages to a broker on a raspberry pi. the values coming from the tasmota sensors node are shown in my last post. The split node can be used to split the message into one message per line. it can be followed by the nodes needed to operate on the individual lines of text, followed by a join node to recombine them back into a single block of text. It would have to be done with 4 change nodes. an example of the msg.payload input would be: {"value1": 1, "value2":2,"value3":3, "value4":4} and the input for the following nodes need msg.payload to equal 1,2,3 or 4. so, splitting each json key into separate payloads. I have an object in my message payload (payload.time) that i would like to split into two separate objects. i think the answer must be really simple with a function node i guess but i am just hitting a stumbling block.
