I'm also considering the Sense, but haven't decided yet.
There's also SPAN Panel [1]. I don't have firsthand knowledge, but the entire panel is "smart", so you can toggle each circuit individually on/off, monitor power utilization, detect patterns, set schedules, etc.
Quite expensive thought -- $4.5K for the device + a massive installation of a new panel, requiring city permits, inspections, etc. I guess the target audience is new constructions and major remodeling, and not existing homeowners.
