Sensus Sonix IQ Gas meter - FlexNet

[pirex00]

Has anyone tried with this device? I have done some research that may be helpful to someone.

There are 2 versions of the Sensus Sonix IQ. SDBSONIXIQ and the new version SDBSONIXIQV2. SDBSONIXIQV2 is the model I am referring to. It appears to operate on FlexNet V2 or protocol 2 using AES 256 encryption or similar. Different config modes determine if it is using 7-FSK, or 13-FSK in most modes, and 2-GSFK when in Mpass mode. Operates on 901-960, with all the specific frequencies listed in the fcc test report.

Not these meters, specifically, but I have a FlexNet water meter I'd love to crack. Maybe the learnings from this will apply there as well?
