The recently released version of EZ Meter Power Suite now supports the EZ Cube line of power meters. While kvah and kvarh are supported, support for harmonics will have to wait for another update.
The Power Suite reads EZ Meter and EZ Cube meters that support Modbus on a user defined schedule. While the meters all communicate through an RS-485 port, any number of technologies can be used to get the data from the meter to the computer including direct wire, wireless, ethernet or internet, whatever makes the most sense for the location.
Data can be accessed through the desktop or sent to a browser with the included web server. The program is useful for power usage analysis and tenant billing,
The full program is free for 90 day evaluation. After that, the web server and and billing features cost $100 per year while basic usage remains available for free. Third party programs can access the meter data either through direct access to the SQLIte database or through a TCP port.
See the Quick Start Guide for more information including a link to download the program.
