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 straightforward 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. There's now experimental support for data collection and aggregation with rtlamr-collect.
Features
- Requires GoLang >=1.11
- For Windows
- For Linux
- Running the receiver is as simple as starting an rtl_tcp instance and then starting the receiver
- Currently the only tested meter is the Itron C1SR and Itron 40G
- User provided, but otherwise unverified compatible meters: Google Sheets
- Track down stray appliances
