A spa node comprising a spa controller, a power sense adapter configured to compute power being drawn by selected spa components; a spa network adapter, and a home network adapter, each of the three adapters including a wireless transceiver wherein the spa network adapter is configured to receive power data transmitted over a wireless link by the power sense adapter and to further receive status/performance data from the spa controller. The home network adapter is configured to receive power and status data transmitted by the spa network adapter over a wireless link and to convert that data to a form suitable for transmission to an Internet access point. The home network adapter is further linkable over the Internet to a central server, a dealer computer and a spa owner or user computer.
