Hi, I am looking for I2C devices(ICs) that I can connect with Arduino to measure Room main AC supply voltages range from 80v to 300v max(usually 220v or 110v), and current consumption that could be 10A max, I am interested in readily available I2C ICs that will do some heavy lifting like calculating RMS voltages, peak voltages and current. Then I can get these values from these ICs and can send to my server via Wifi.
Any well known ICs that can be easily available?
I have some space constraints, this circuit will be fitted into a close box of 16 centimeter width, 8 centimeter height and 8 centimeter depth. In this box there will be some SSR and power supply as well.

Yes, there several chips that can measure A/C rms volts and amps.
But then adding the I2C requirement and peak values, limits your selection.
@mrsummitville I am open to other techniques too, until unless they can be fitted into the described space, and secondly I have one ADC pin or one I2C bus left.
But then what about voltages measurement? I need to use voltage transformer for bringing down the 220 voltage to ADC level, And second thing is I have only one ADC pin, And I want to measure current and voltages both, and don't want to include any kind of multiplexer into PCB. There I asked for IC that can be interfaced with Arduino or ESP module using I2C bus.
