Desire to save is among the most prominent reasons when people decide to get a smart meter. While saving energy is good for the planet, it also works wonders for home budget, making smart meters a win-win solution. The best smart meters also measure more than just W and kWh (import and export), but also V, A, W, PF, kVAh, and kvarh. You should always consult a manufacturer or seller before deciding which smart meter is the best choice for you. When equipping your home with smart meters, you can only monitor systems and appliances which use the most energy, like electric domestic water heaters, or monitor your home as a whole with a smart monitor attached to your electrical cabinet. The best choice is, of course, monitoring individual devices and entire consumption, allowing smart meters not only to measure but also analyse consumption of energy in your home. By tracking energy consumption on your smart phone or tablet in real-time, you can get a feel of where your house is “leaking”, while a month’s worth analysis will help you make informed decisions as to what measures you and your family should take to lower your overall energy consumption. If your home has individual energy sources like solar panels, smart meters will measure both gathered and spent energy and calculate surplus or deficit. Needless to say, you can remote control your smart meters, turning them and your devices off and on from wherever you are. With smart water heaters, for example, you can not only track the amount of energy consumed, turn them on or off, but also set the thermostat and upper limit of energy consumption. After reaching the pre-set consumption limit, the smart meter will notify you about turning off your water heater (or any other device) via your smart phone.
