::Clipsal via ::Red FerretA sensor is connected to the main line, and broadcasts a signal up to 30 metres to the receiver. One ominous use of the device: It Is a remote reading monitor developed to meet community demands for energy efficiency. Not only you but perhaps your community can be watching.
"Knowledge about the amount of power used enables consumers to make informed decisions about choosing energy efficient appliances, use of sustainable "green power" source, reduction of stand-by power losses and re-scheduling of unnecessary consumption during peak load periods. The monitoring of ambient comfort levels inside the home encourages efficient use of space heating and air-conditioning that are substantial energy users.
"The Clipsal CENT-A-METER™ comprises of a sensor, wireless transmitter and receiver. The sensor is a clip-on current transformer that samples the electric current on each active phase wire inside the switchboard.
These readings are aggregated and relayed by the 433 MHz wireless transmitter to the remote receiver/monitor. The receiver computes the approximate power use, energy cost and greenhouse gas generation and displays the results on a large portable LCD screen. Consumers can input specific country currency and voltage, electricity tariff rate, greenhouse gas conversion factor and peak load alarm value."
