Belkin's slim, power-tracking WeMo Insight Switch (pictures)

Belkin's pair of smart plugs, side by side.

The status window in the new WeMo Insight Switch is easier to see from a distance. The LED could still be brighter.

Belkin says the new USB input could support add-on devices in the future.

The WeMo Insight Switch has a smaller body, but it can still block an adjacent power outlet.

It's better this way.

Here's the standard screen for the Insight switch, with all of the power draw data on display.

Belkin doesn't expose a ton of settings, but at least you can adjust a few important ones.

On this screen you can raise or lower the power draw level the WeMo Insight Switch uses to determine whether it's in standby or power mode.

Set your local power rate to get the most accurate usage cost data.

Like numbers? Belkin will send you a ton of them via this exporting tool.

The WeMo app will send you a trove of data, reporting on daily energy usage, cost, and so on.

The WeMo Insight Switch IFTTT channel has plenty of free, useful recipes like this one.
