Hi, if you just want to read the current and volts then an ammeter and a voltmeter mounted in your house sub panel will do the job. Of course the ammeter will require a shunt to carry the current. Needless to say to wire the meters requires somebody who is suitably qualified. Normally this work requires an electrician. The voltages involved can be lethal.
Otherwise, there are products like the "owl" which monitor the electricity consumption by using a current transformer which requires no electrical skills to install.
