Do you want to save energy? Try Energy metering. Monitoring of energy consumption is possible both on existing installations and on newly installed gauges. The system allows you to measure the consumption of electricity, gas and water.
Energy consumption is primarily displayed in units of time, but if you are wondering how much current consumption is costing you in real money, it can be set.
Charts and spreadsheets inform you of the history of energy consumption, the current trends. You can also set limits or report regularity.
