EasyIoT server require much more resources than Arduino can provide. It has nice HTML5 WEB interface, automation functions, data logging, secure SSL connection. All this is hard or even impossible to implement in Arduino. You need only one EasyIoT server on Raspberry Pi and then as many as you wish Arduino sensors around house.
