The electricity monitor
The Lightwave Energy Monitor shows your energy usage in real-time and tells you how much your energy is costing per hour, just like a smart meter.
Turn off devices using the app
However, Lightwave goes one better, as now you can save energy by turning on/off energy hungry appliances from your phone and see how your usage changes. If you think that you have left a power hungry device on, check with the energy monitor and turn it off remotely!
