    This URL from Description: “Most on board information please read on this page.” not working. Check it please.
    Can’t get working library. So get wrong Voltage measurement.
    Calibrate values, get:
    hlw8012.setCurrentMultiplier(8755.00);
    hlw8012.setVoltageMultiplier(313000.00);
    hlw8012.setPowerMultiplier(6553038.00);

    But it’s looks like that get voltage correct only on calibrated power. When power is 0 I have 0 voltage too.
