ZigBee Powers the HAN ZigBee provides an open wireless standard for the HAN [Home Area Network] enabling device networks in the home for load control e.g. Heating/AC, Security, Lighting, Appliances. 14

HAN Guiding Principles Secure 2-way communications between the AMI Network and the HAN Load control integration (e.g., distributed resource dispatch / control / relaying) Direct access to usage & other meter data (e.g., kwhr, KW, Voltage, etc.) Platform for future customer owned products which leverage meter data and utility/grid information Three types of communications: public price signaling, consumer specific signaling and control signaling Supports communications to other HAN Devices with metering capability (e.g., gas &/or water meter communication, EV sub-metering, PV sub-metering, etc.) AMI Network interface to HAN interface is based on open standards Implementation is appropriate given the high value and relative low cost Potential technology obsolescence is low due to multiple bridging options ZigBee Supports all of these Principles Source: UtilityAMI OpenHAN Task Force 15
