Power calculation

Maxim provide a pretty cool chip to measure current an voltage on 230Volt grid : http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5673

Logging

The idea is to use APF9328 with SDCard to log measurement each 30 seconds.

Human communication

The HME (Home Monitoring Energy) can be a home server branched to home network via apf ethernet interface, but it can also use LCD touchscreen to provide an interface for some manipulation.

Devices communication

The HME can communicate with other home device like heating systems to shutdown it when electricity consumption is to high. The communication can be with:

  • zigbee
  • X10
  • ethernet
  • ?

Powering the HME

HME must work all the time, even if home current shutdown. To meet this requirement a battery as to be added. The simplest and cheapest battery is lead battery, then this battery will be used.
