The Opta can be an irreplaceable support for home energy management. Getting information on instantaneous electrical consumption and interacting with the customer's consumption plan, daily usage statistics, and seasonal forecasts can help in planning and managing electrical devices to optimize energetical efficiency. Always be connected and informed by integrating the Arduino IoT cloud and add self-adjustment capability by monitoring and logging electrical statistics along with the option to operate the connected devices on-demand based on pre-set triggers.
