The intimate communications hub interface (ICHI) allows for the attachment
of an intimate communications hub which, together with the meter, can
support smart metering applications in accordance with the UK SMETS2
specification for smart metering.
Where the ICHI is not used (e.g. for install and leave applications), the
meter must be fitted with a cover to restrict access to the ICHI. This is
secured using a one-time tamper-resistant screw and must be employed
if the communications hub is not fitted due to the presence of
dangerous voltage levels on the ICH interface.
For SMETS2 operation, the ICHI provides power to an intimate communi-
cations hub in accordance with the ICHI specification promulgated by DCC.
Note that power line communications (PLC) is not used in this model.
