Addition functions of ESS model 2
 Detection of active standby power mode of appliances
 Cut-off of active standby power
 Monitoring of energy consumption status (optional function)

Feasible types
 a stand-alone system
 functional modules that can be implemented into legacy home gateway (or home server)

Requirements related to
 Functions of appliances, ESS clients and ESS server
 Saving of context of an appliance before cutting off its supply of electric power
 Restoration of context of an appliance after supplying electric power
 Simple communication protocol for power-monitoring and power-control between
ESS clients and server

Functions and Classification (1)
1)
Appliance
①
Supporting devices

Legacy home appliances and legacy home network devices


New home network devices which meet this specification

2)
ESS clients cut off only passive standby power of legacy devices.
ESS server and clients cut off both of passive and active standby power.


③
Function 1 : Cut off the supply of electric power by itself or an ESS server
Function 2 : Detect passive standby power mode of appliances connected to it
Function 3 : Detect active standby power mode of appliances connected to it
Function 4 : Calculate (or measure) the amount of consumed power (or electric current
and voltage) and send result to ESS server
Class 1 : ESS clients which meet Function 1 and 2 above (for ESS model 1)
Class 2 : ESS clients which meet Function 1, 2 and 3 above (for ESS model 2)
Class 3 : ESS clients which meet Function 1, 2, 3 and 4 above (for ESS model 2)
Feasible Types




②
Build DB by using data from ESS clients
Query functions (with device name or ESS client ID)
Display total amount of power consumed during a specific period
Energy saving function


Be notified the active standby power mode of appliances
Send control commands to ESS clients in order to cut off the supply of electric power
Send query commands to ESS clients in order to monitor the power consumption status of
appliances
Cut off active standby power consumed by home network devices
User-configurable interface and alarm service
Feasible Types



Type 1 : stand-alone type (no connection to home server or home gateway)
Type 2 : stand-alone type, but it is interoperable with home server or home
gateway
Type 3 : home server or home gateway type (can be implemented as additional
functions of home gateway (or home server))
