GBCS Integration Testing for Industry (GFI)

The tool allows you to emulate the sending and receipt of GBCS messages and help identify any potential differences with your interpretation of the specifications.  GFI covers all electricity and gas smart metering equipment (ESME and GSME) Use Cases covered within GBCS v0.8.1.
GFI is not available as a download but delivered on a USB memory stick along with a specifically-programmed USB -connected ZigBee radio; which allows GFI to communicate with your intended meter. GFI also includes meter simulators.
