SmartMeter mit 900 MHz ISM-Protokoll mit SoftwareRadio mitlesen

[Morgennebel]

Utilities often use "smart meters" to optimize their residential meter reading infrastructure. Smart meters transmit consumption information in the various ISM bands allowing utilities to simply send readers driving through neighborhoods to collect commodity consumption information. One protocol in particular: Encoder Receiver Transmitter by Itron is fairly straight forward to decode and operates in the 900MHz ISM band, well within the tunable range of inexpensive rtl-sdr dongles.

This project is a software defined radio receiver for these messages. We make use of an inexpensive rtl-sdr dongle to allow users to non-invasively record and analyze the commodity consumption of their household.
