Easy Home Offtake is a utility which allows you to track your energy consumption in your home. It can serve as an important document in case of a faulty billing. The application is a simple tool that allows you to record consumption of gas, electricity and water in your home.
It is not necessary to specify the type of meter (kWh, m3, kJ, etc.), because the number of pieces is taken from the number of the consumed units. But if you want to see consumption of a particular type of meter, you can set it in settings. The basic categories are: GAS, HOT WATER, COLD WATER and ELECTRICITY.
