You can see the difference in your monthly electricity bills. What about its cause?

When maintaining your household account book or receiving an electricity bill, have you ever thought why this month’s electricity bill is so expensive?
It is troublesome to explore the cause of the expensive bill and you spend the following month just on a guess. Consequently, the electricity fee will rise without measures.

“ViewE” can visualize the electric power! If you know how much electricity is used for what, saving electricity and living an eco-friendly life are not difficult.

Let’s start an energy-saving life with “visualization”

You can see daily, monthly and yearly power consumption graphs for the entire house or each circuit breaker with ViewE on your PC, smartphone or tablet.
You can use it even while on the go, which helps to prevent you from forgetting to turn off the lights.

“Visualization” of power consumption

With ViewE, you can compare the power consumption with the previous day, month or year to know its trend. Moreover, consumption by each circuit breaker can be checked in real time (*data is updated every 30 minutes), and you can quickly notice the cause when you become concerned about any power consumption status.
