CACI Limited Testimonials

"CACI were able to bring deep knowledge on device testing onto the nPower team across both SMETS 1 and SMETS 2 technologies and have been a great asset on the nPower Smart Metering Programme. In helping scale our test operations, CACI quickly deployed test leads, device testers and test analysts with the right mix of skills in SMETS 2 and SMETS 1 device testing. Their experience of smart meter testing coupled with their knowledge of the full protocol stack including Zigbee, GBCS, GBZ (DLMS), GBT, DLMS/COSEM enabled them to make a big impact on the test programme from the start. They have played a key role in test strategy development, test execution and test analysis as well as training and the upskilling of other nPower team members. Their skills in capturing, decoding, interpreting and analysing device (ESME, GSME and PPMID/IHD) logs, Comms Hub (CHF and GPF) logs and Head End System packet traces in addition to their understanding and use of GFI (GIT for Industry) for testing of remote (SRV) and local (HAN only) commands has been critical to the success of the testing programme."
