Does anybody know of a product that will monitor the electricity usage of a 240V dryer machine in a given period (like for the whole month)? I was able to find such a device for my washer machine, however the washer operates in 120V. I bough it at home depot and it is called P3 Kill A Watt. I looked all over the internet and i dont seem to find the same device that will work on 240V. ANy ideas? I would really appreciate it!
