There are a lot of devices that have reasonably distinct patterns to their power consumption. Motors- especially well pumps, but also large central air fans and some others- are going to look very different from a microwave or vacuum cleaner or refrigerator, especially if you have time of day on your readings.
Constant lower draw devices- chargers, lights, speakers and such- are going to be harder to distinguish, though.
