Open Energy Monitor Esp32

To keep component count low and the circuit as simple as possible the ads1115 is used in differential mode eliminating the need for bias resistors. The emontx v3 uses a 3 3v regulator so it s v cc and therefore aref will always be 3 3v regardless of battery voltage. There are power guzzlers in every household that go about their business unnoticed such as the old electric cooker the tv in stand by mode and illumination with conventional light bulbs.
