recognizing a user'"'"'s behavioral pattern and providing occupancy estimation based upon different use scenarios.

6. The method of claim 5 wherein the device is a remote device remote from said load power devices.

7. The method of claim 5 further comprising enabling configuration of load management and control policies.

8. The method of claim 5 further comprising providing sensorless occupancy estimation.

9. The method of claim 5 further comprising:

detecting activation of a pushbutton of one of said load power devices of greater than a first predetermined time and responsively changing an on or off state of one of the at least one power output; and

detecting activation of said pushbutton of smaller than a smaller second predetermined time and responsively turning off said one of the at least one power output after a third predetermined time.

10. A system providing load control and management based upon load identification, said system comprising:

a plurality of load power devices, each of said load power devices comprising;

a power input,

at least one power output for at least one load,
