Well... Seems as if the engineering team decided to leave out an important detail. The nodes won't transmit usage data if the wattage is below a certain level! I have been using a couple of dinky little clock radios. So I decided to try and plug something more substantial into them, (a couple of old G5 towers sucking 170 watts a piece) and presto chango, My Program Works!

Thanks again to everyone for all of your help, and sorry to have bothered you all with a problem that wasn't really a problem,

Tim
