Benefits of Submeter in EVSE

Sub-meter embedded in EVSE communicates securely with 3rd party EVSP cloud based system. EVSP system in turn communicates securely with Utility MDMS

Sub-meter embedded in EVSE communicates securely with utility as end node attached to the AMI edge router (using vendor specific AMI protocol e.g. SSN’s 802.15.4 mesh)

Sub-meter embedded in EVSE communicates securely with utility via premises smart meter using utility controlled HAN network e.g. ZigBee SEP
