The only thing is that you do need to have a microcontroller send the "Start Logging" command

not SPI - since it speaks I2C you can easily connect it up with just two wires (plus power and ground

Xboard Relay - An Ethernet Controllered Relay Brand_Rii The only thing is thatInternet of things has become so easy. With Xboard Relay, you can not only monitor data through internet, but also control it through internet. The Xboard Relay combines an Atmega 32u4 microprocessor and wiz5100 chip which is fully compatible with Arduino Leonardo and Ethernet library, it has build in Xbee socket and 2 Relays which allow an easy sensoring and controlling over internet. As the W5100 Ethernet chip will get hot, when it is working. You
