glynnbebee on Multiple temps in one message - help please.

Wondering if anyone has a minute and can tell me how to modify this code to send multiple temperatures to Thingspeak?

I have working the Electric Imp code to send 1 temperature, but have not been able to modify it to send 6 temperatures.  The temperatures are stored in an array.  I'm getting datapoint.temp[1] through to Thingspeak, but don't know how I would also send in the same message datapoint.temp[0], datapoint.temp[2], datapoint.temp[3] and datapoint.temp[5].

 

The Device Code I have now is:

local datapoint = {
    "id" : id,
    "temp" : [ format("%.2f",myThermistor0.read_f()),
                format("%.2f",myThermistor1.read_f()),
                format("%.2f",myThermistor2.read_f()),
                format("%.2f",myThermistor3.read_f()),
                format("%.2f",myThermistor4.read_f()),
                format("%.2f",myThermistor5.read_f()),]
}

agent.send("thing1", datapoint.temp[1]);

 

The Agent Code (online Web-IDE) I have now is:

local thingSpeakUrl = "http://api.thingspeak.com/update";
local headers = {
  "Content-Type" : "application/x-www-form-urlencoded",
  "X-THINGSPEAKAPIKEY" : "MY KEY IS HERE"
};
local field = "field1";
function httpPostToThingSpeak (data) {
  local request = http.post(thingSpeakUrl, headers, data);
  local response = request.sendsync();
  return response;
}
device.on("thing1", function(analog_value) {
  local response =  httpPostToThingSpeak(field+"="+analog_value);
  server.log("House Temp Samples: " + response.body);
});

 

Thanks in advance for pointers on how to proceed.
