The Open Metering System

The Open Metering System (OMS) is the only system definition across Europe which integrates all media (electricity, gas, heat and water incl. submetering) into one system. It was developed by the industry in order to guarantee a future-proof communication standard and interoperability between all the meter products.

The OMS specification is open and patent-free viable

The OMS specification describes the two-way communication between an OMS device, e.g. a smart meter, and a communication device (gateway). The OMS specification is publicly available and can be realized without any patent-infringements by all interested parties.
