I often see website ads for home electricity meters that check on home power usage in order to help save costs by monitoring what is used so homeowners can adjust their usage to cut costs. However, is there a much more sophisticated meter available that oversees actual home usage and compares that to the amounts utility companies state that we have used in our monthly bills? As far as I know, there has never been a convenient way to double check utility company charges and we have had to just pay the bill even if we thought/knew charges were excessive. It seems to me to be possible............by attaching the electricity meter to incoming leads before they get to the panel box thus before any usage. That would seem to help with those nagging doubts we all have about utility charges, and especially now that many utilities have gone to "Smart Meters" which have been seen to be suspect in that some customers with those installed say they think they are smarter for Big Utility than for the consumer. Confirmed accuracy would have to be well addressed and certified, as if not Big Utility could always say our home meters were innacurate and theirs were right so too bad, pay up or else. Informed and qualified answers and discussion are requested. Thank you all.
