The Intimate Communications Hub Interface (ICHIS) specification defines a common interface between Intimate Communications Hubs (ICH) and Smart Meters which will be deployed for the GB Smart Metering Implementation Programme.

The ICHIS defines the mandatory features required to ensure that an ICH can be used with any ICHIS compliant Host, as well as defining features reserved for future use or for specific implementations.

DCC will review the ICHIS as a minimum on an annual basis to ensure it remains fit for purpose and use. The review in February 2015 resulted in no changes. It is anticipated the next review will take place at the end of the Systems Integration Testing stage.

Outside of the annual review, if you identify any changes or updates that are required, please email contact@smartdcc.co.uk detailing the proposed change and accompanying rationale for the change.
