OMS is an open and cross-vendor communication standard for smart metering based on European/ international standards. OMS is the only energy measurement system which is both open and standardized and integrates the consumption values of all energy sectors into one system: electricity, gas, thermal energy, water – in metering and sub metering. Communication is based on the proven M-Bus standard. The wireless M-Bus/ OMS standard (EN 13757-4) describes the communication between an OMS device, e.g. a gage, and an installed communication device (gateway)in both directions. The OMS specification is publicly available and can be implemented by all interested parties without a patent. The OMS Group has developed an OMS test specification and a conformance test tool and also offers certification for OMS devices. This ensures the implementation of the standard in all certified devices.
