(update) the feed is working – I changed the datastream name from sensor_value to count – and just had it upload a random value every time for testing.
Some initial testing with the Ethernet shield encountered missing libraries when compiling the example sketch which cosm.com provides when setting up an Arduino type feed.
Here is the forum post which explains which libraries are missing: http://community.cosm.com/node/1694
and here is the helpful quote…
You should try using new official Cosm library for Arduino.
You can download a snapshot zip file here:
https://github.com/cosm/cosm-arduino/zipball/master
You will also need this HTTP library:
https://github.com/amcewen/HttpClient/zipball/master
See here for more details on how to install a 3rd-party
library on different OS:
http://arduino.cc/en/Guide/Libraries
You will find a bunch of usefull examples within the
Cosm library. Please let me know if you have any questions.
