CRC check is set to false in the sample flowgraphs so you will see data but can't be sure there aren't any errors. Every power provider is assigned a unique CRC so neighboring smart meter systems do not interfere with each other. To determine this you need to capture at least 4 good packets and use reveng to reverse the CRC. | CRC check is set to false in the sample flowgraphs so you will see data but can't be sure there aren't any errors.
