## Abstract

A system and method for reducing load across a portion of a power grid. The system (400) includes an access manager device (200) that forms part of a local power management network (600) and is configured for communication with a smartphone (10) and a smartmeter (300).

## Claims

### Claim 1

A device for linking a personal controller to a smartmeter, the personal controller having a processor, a user interface, and a wireless communications transceiver, the smartmeter being configured to at least measure power flow, said device comprising:
a wireless communications module operable for wireless communication with the personal controller, said wireless communications module including an aerial and a radio transceiver, said wireless communications module being configured to communicate wirelessly with the personal controller in at least two different modes, a first of the modes being a peer-to-peer communications mode, a second of the modes being a non-peer-to-peer communication mode;
a local network communications module operable for communication with the smartmeter, said local network communications module being configured to communicate with the smartmeter using an IEEE 802.15 series communications standard;
an interface connection for physically connecting said device to a mains power line, said interface connection being configured for plug and socket engagement with a mains power outlet; and
a microcontroller configured to access, through said local network communications module, the smartmeter based at least in part on instructions communicated from the personal controller through said wireless communications module, said microcontroller being configured to relay data measured by the smartmeter from the smartmeter to the personal controller using said local network communications module and said wireless communications module, said microcontroller being configured to change from the first mode to the second mode upon wirelessly receiving instructions from the personal controller for said radio transceiver to operate in the second mode.

### Claim 2 (depends on 1)

The device of claim 1, wherein said local network communications module is configured to communicate with the smartmeter using only an IEEE 802.15 series communications standard.

### Claim 3 (depends on 1)

The device of claim 1, wherein said local network communications module is configured to communicate with the smartmeter using Zigbee.

### Claim 4 (depends on 1)

The device of claim 1, wherein said microcontroller is configured to relay data stored by the smartmeter from the smartmeter to the personal controller using said local network communications module and said wireless communications module.

### Claim 5 (depends on 1)

The device of claim 1, wherein said microcontroller is configured to open a peer-to-peer wireless communication link with the personal controller using a SoftAP.

### Claim 6 (depends on 1)

The device of claim 1, wherein said microcontroller is configured to relay instantaneous power measured by the smartmeter from the smartmeter to the personal controller.
