Hi! I would need help on this matter. How do I differentiate the Var, so it does not take the same values as shown in the attachment.
msg.fecha=new Date();
var fecha = msg.payload
var Tension1 = msg.payload
var Tension2 = msg.payload
var Tension3 = msg.payload
msg.topic = "INSERT INTO sepam(fecha,Tension1,Tension2,Tension3) VALUES (+'"+fecha+"',+ '"+Tension1+"',+'"+Tension2+"', +'"+Tension3+"')";
return msg;
You have set all three to the value of msg.payload, so they will all be the same. Are you sending multiple messages to the node and need to combine the data from those messages? If so then you can use a Join node for that. See this article in the cookbook for an example of how to join messages into one object.
If the values are not coming from multiple messages then you need to give us more information.
