Remoticon 2021: Smart Meter Hacking Talk
Remoticon 2021 was an online conference held in November 2021 and videos of presentations have recently been uploaded to the Hackaday YouTube channel this month. One very interesting talk was the presentation by Hash Salehi (RECESSIM) on reverse engineering electricity smart meters that are used to remotely monitor and bill home electricity usage in some neighborhoods.
In the past we've posted about Hash (RECESSIM)'s series on smart meter hacking a few times before. In this latest talk Hash summarizes his smart meter hacking experience, talking about how he went from reverse engineering the firmware, to using an SDR to capture and decode information from all the smart meters in his neighborhood, and finally to determining how to actually transmit data to his own smart meter network.
Hackaday have also posted a full writeup on his talk. This is a very in depth reverse engineering project so it is a great talk to learn from.
