The Smart Meter Device Assurance Scheme

The SMDA Scheme has been set up to provide assurance to consumers, suppliers and financiers that smart meter equipment will work effectively in a smart environment. The Scheme provides assurance testing of smart metering equipment covering both interoperability and interchangeability of the devices.

Interoperability is an obligation on energy supply companies, requiring that smart metering devices interact with the Data Communications Company (DCC) systems and can successfully receive, interpret, act on and respond to messages.

Interchangeability testing checks that all devices on the Home Area Network (HAN) can communicate with one another and interpret and act on commands. It is beneficial to the industry in order to reduce the risk of ‘stranded’ assets.

SMDA is unique in that it is the only assurance scheme that tests each device against multiple devices. We use over 300 test scripts in our assurance tests.
