Thanks, although not quite what I'm looking for
I've built little arduino gadgety relay controllers using GPRS shield etc, but want something less DIY and more easily expandable. E.g. when I have a new pump that needs to be turned on, I can just plug in another relay widget and start controlling it.
XBee PRO can do the range, but all the ready made kits seem to insist on sticking it onto an arduino. I really don't need the arduino bit, just want the xbee + relay! I thought the market would be flooded with this type of thing.... apparently not
