I Installed Ohm assistant energy monitor device few months ago. I needed one single device that could monitor all the appliances at home, so that it will be easier for me to record and take complete control over its usage. This energy power saver not only displays accurate data but also displays the consumption in the same measurements the electricity company does, and the data is not complicated as well. I can easily to predict the cost of future bill and the power consumed by the end of the month. That is how I control the usage and consumption in the following moth. This device has made a huge difference in usage electricity consumption and has made it simpler due to its user friendly app.
