After using Pachube/Cosm/Xively for quite a while while the Electric Imp planner was still in use, I wanted to try something new and simpler with the new Agent.
With the new firmware (release 27.9) it is now possible to get a reading of the light level, so why not make a little tutorial on how to log this?
After creating a project on the devicehub.net site you will get a API key and project number. Insert the two into the agent code.
You will also need a sensor. Create that on the site too and insert it’s name into the agent too.
local devicehubApiKey = "api key here";
local devicehubProject = projectnum;
local sensor = "sensor name";
addDevicehub(devicehubApiKey, devicehubProject, sensor, msg);
function addDevicehub(key, project, sensor, value)
local url = "http://devicehub.net/io/" + project + "/?apiKey=" + key + "&" + sensor + "=" + value;
if (resp.statuscode = 200)
server.log("Devicehub sensor '" + sensor + "' got updated with the value " + value);
server.log(format("%i: %s", resp.statuscode, resp.body));
On the device we collect the numbers we want to send to devicehub, then sends it over to the agent.
imp.wakeup(60, devicehub); //Do this again in 1 minute
This should now end up looking something like this: http://devicehub.net/project/221/
