Hi, I am a noob in this. I am working with wireless Vibration and temperature sensor. I want to send an email alert of vibration and temperature. I have created a function node to send a single value. [error1] it's working. but I want to send multiple values in a single function node. [error2] …

Yes sir I got your point. var results = ''; if (msg.payload.temperature > 28) //You can add value according to your need { //Temprature = "Temprature "+msg.payload.temperature; results = results + "Temprature "+msg.payload.temperature; } if (msg.payload.humidity > 80) { results = res…

Go and look at the link on sending messages again. You have written it to send each message to a different output (but have only allowed one). You want to send all the messages to one output.

I have connected debug node to this function node only [error5]

Is that comment a reply to my point about the fact that have coded it to send one output to multiple outputs instead of multiple messages to one output? If so then I don't understand the relevance of it.

I want to send multiple values in a single function.otherwise I have to create multiple function nodes to send multiple values.

So you want to send multiple values in one message? i.e just as they arrived in your function node? Or do you want to send different values in different messages along one wire to the next node Or do you want to send different values in different messages to different nodes?

I want to create email alerts for a particular value of vibration and temperature. But Vibration comes in different values like rms_x,rms_y,rms_z etc [error2] I have created a function for sending temperature value [error6] like this i want to create alerts for different vibration values. But…

Hi @adamf If you want each of those messages to be sent, one after the other, from the single output of the Function node, then all you need to do is change: return [ RMS_X, ..., Temperature] ; to return [ [ RMS_X, ..., Temperature ] ] ;

Alternatively, if you want to conditionally send some messages you could do: if (msg.payload.temperature > 25) { node.send({ topic: "Subject: System .... ", payload: "Temperature:" + msg.payload.temperature; }); } if (msg.payload.otherProperty > 10) { node.send({ topic: …

[image] adamf: i want to create a single function for multiple values ,like above example In that case you were nearly right in the function posted, except you have told it to send them to multiple outputs. As I said look again at the link posted. You need to send an array containing an arra…

Do you want to send multiple messages each containing one value, or one message containing multiple values? We have assumed here that you are trying to send multiple messages as that is what you seemed to be asking and what you coded into your function node. Your data coming in is already multiple values in one message so it is not at all clear what you are trying to do.
