Test House

The SMDA Operator required a Test House capable of providing test services for the SMDA scheme which resulted in the exclusive appointment of NMi Certin BV on 23rd December 2016 as SMDA Test House.

NMi are an internationally recognised Dutch test house and certification body and were chosen to ensure a cost-effective scheme that is both capable of achieving a high quality and capacity for testing.

A specific SMDA test facility in Southampton opened in mid-2017. All the interoperability and interchangeability testing will take place in this facility. The testing consists of two parts:

  • Interoperability relates to the ability of Type 1 devices to interact with the Data Communications Company (DCC), successfully receiving, interpreting, acting on and responding to messages. 
  • Interchangeability goes further, checking that all devices on the Home Area Network (HAN) such as in-home displays, meters, pre-payment interface devices or HAN connected auxiliary load switches can communicate with one another, interpret and act on commands, no matter what brand is being used.
