The Lightwave Electricity Monitor allows you to keep track of your electricity use in realtime from your smartphone or tablet from anywhere. Use Lightwave to turn off power hungry devices then compare the power usage. This is a great way to help understand your consumption habits and to reduce your electricity bills. The Electricity Monitor simply clamps onto the incoming live electricity feed in your home. This is safe, can be done in seconds and does not require an electrician or any special knowledge. The monitor requires the Lightwave Link or Link Plus and the Lightwave App to be able to operate.
