[Encoder receiver transmitter](https://en.wikipedia.org/wiki/Encoder_receiver_transmitter) (ERT) is a packet radio protocol developed by Itron for automatic meter reading. The system uses OOK short range radio which is transmitted in the unlicensed 900-920 MHz band, so that meters can be read from a passing vehicle. This is mainly used in USA.
The data is not encrypted, and does not have functions to enable full control. The system is not as advanced as a smart meter and lacks the control or security in the data transfered.
