My take. As @JustinAtSense, suggests, smart plugs are good for reducing Other and Always On in a targeted way, once you:

  1. have a good handle on what Sense is detecting and not detecting in your house
  2. have a good view of of the relative Always On and typical usage for devices that Sense is not detecting. That’s probably the best use of your HS300 (or a KP115) right now, as a roamer, looking at the 24-48 hour time histories of all the plug-in devices that are unlikely to be detected. That gives you a way to best use smartplugs if you want to reduce Always On and Other, beyond Sense detections.

Here’s a simple view of what’s likely to be detected by Sense and what’s not.
