What is "openhan"

The OpenHAN standards for home networks (sometimes called home grids) was promoted by groups such as openAMI and UtilityAMI. Both efforts aim to standardize powerline networking interoperation from a utility point of view and ensure reliable communications co-extant with AC power outlets.

Both utilities and vendors of home control have promoted such standards aggressively . The openHAN label usually denotes standards favored by the utilities, not other service providers. It should be distinguished from the openADR standards that were promoted to ensure open access to customer electricity use data by all service providers.
