  • Scroll down to the “Decoding Function” section and paste the following code on the text field:

function format_payload(args){

var messages = args["uplink_message"]["decoded_payload"]["messages"];
var ubidotsPayload = {};
var varLabelMap =
{
4175:"AI-detection-1",
4176:"AI-detection-2",
4177:"AI-detection-3",
4178:"AI-detection-4",
4179:"AI-detection-5",
4180:"AI-detection-6",
4181:"AI-detection-7",
4182:"AI-detection-8",
4183:"AI-detection-9",
4184:"AI-detection-10"

};

messages.forEach(msg => {
if (msg.hasOwnProperty("measurementId")) {
ubidotsPayload[varLabelMap[msg.measurementId]] = msg["measurementValue"];
}
});

return ubidotsPayload;
}



module.exports = { format_payload };
