Utilities often use "smart meters" to optimize their residential meter reading infrastructure. Smart meters transmit consumption information in different ISM bands, which allows utilities to simply send readers through neighborhoods to collect product consumption information. One protocol in particular: Encoder Receiver Transmitter by Itron is fairly straightforward to decode and operates in the 900 MHz ISM band, well within the adjustable range of inexpensive rtl-sdr dongles. This project is a software-defined radio receiver for these messages. We use an inexpensive rtl-sdr dongle to enable users to non-invasively record and analyze their household product consumption.
