What software and hardware do you recommend to gather data from the WattNode® Modbus® meter and to configure the CT amps? The best option is to use a product that is “WattNode meter aware” and has built-in support for the WattNode Modbus meter’s register map. Examples are:

    • eZE System, Inc. The standard eZEio Controller is an Internet communications gateway device that connects WattNode Modbus meters to eZEio’s server. In addition to energy logging, the Controller supports analog inputs, control outputs, and email alarms, using only a web browser. Option for GSM cellular radio built-in for locations without a wired Ethernet access.
    • i.Lon® SmartServer has built-in support (register templates) for WattNode Modbus meters. The register template is available here: WattNode_template.zip
    • Infinite Automation Systems, Inc., (303) 558-7112, Boulder, CO 80301

  • Obvius has built-in support for WattNode Modbus meters.
  • Logic Beach supports the WattNode Modbus meter with their IntelliLogger™.
