POWER CONSUMPTION FEEDBACK SYSTEMS
First Claim
1. An electrical power supply consumption feedback system for providing feedback on power consumption in a building, the system comprising:
- a current transducer configured to be attached externally to a mains power supply cable providing a mains power supply to said building to measure a current of said mains power supply;
a voltage measurement system configured to measure within said building a voltage of said mains power supply;
a system controller coupled to said voltage measurement system and to said current transducer and having a system controller wireless interface, at least one of said current transducer and said voltage measurement system having a complementary wireless interface and being coupled to said system controller via said system controller wireless interface, and wherein said system controller is configured to calculate a power consumption of said building from said measured current and voltage; and
a display coupled to said system controller to display a visual indication of said calculated power consumption.
