The super cheap (for what it is) Kill-a-Watt does have the ability to average power over what might be a period of days.

There are also quite a few under $500 DSOs out there that could be used to measure power. You do need to get an isolated voltage probe and a current probe to measure mains (or an isolation transformer/other isolated source of AC power), but that's a hardware upgrade.
