power metering and control

Hi guys
Can i make arduino monitor power consumption by the home,
For example if the house is consuming more than 10KWh it will send notification to the user

And can i make it tell which devices are on and give option to turn them off wirelessly?
(need name of the parts plz)

I am doing some researches but i want to make sure before buying stuff
Thanks

I need to do it with arduino

If you are not familiar with electrics and electronics, keep your hands off mains voltage!

Use secure modules for detecting the current consumption of your devices. The many distant places for measuring these currents suggests a network, and that's where home automation modules simplify building such a network. Using the power lines for data transmission will eliminate the need for the many cables to every single sensor.

Did you read the Site I have link, it is for Arduino

The voltage is 220
What i want to know how to measure is the current and energy (KWh)
Then when the house is consuming more than it should i can wirelessly turn of some machines

Start with just one sensor and get it working well, then do the same for another sensor. Don't ever start of a new project with so many unknowns.
