It is vastly cooler having a whole house electricity monitor. With this you know if the major(and smallest) appliances use, if they are operating and when. I have zero surprises if I leave the home for any length of time and I can make intelligent decisions on home improvements. Is an electric attic fan expensive over a solar? I know that level of detail. Will solar pay for itself? Will changing the home temp save much??
Many people who mean well on this board are simply wrong, repeating the same myths
