“Home Snapshot” enables visualisation of device usage

うちワケ

Home Snapshot enables device power usage to be visualised and managed.
Provide a daily snapshot of energy usage in your home.

A small smart sensor installed within your Consumer Unit (Mains Fuseboard) collects, analyses and reports the electricity usage in your home. The reports can be viewed online or on your mobile enabling you to check on your energy usage even whilst away from home.
