Hi,
The feed cosm.com/feeds/1393 shows the use of sensors Grove - SeedStudio in Cosm.
Cosm is everything you know and love about Pachube, with more power to connect and build the Internet of Things today.

It is cool 
, I have also sent some data to Cosm by Wifi Shield , but just test the Shield .
By the way , can you provide the recipe that how you connect the hardware and upload data to Cosm. That will be useful for other guys. 
Thanks in advance.
