The new light switch comes in two skews. There's a $50 version that's newly compatible with three-way setups where more than one switch is wired to the same light, and there's a $40 single-pole version that isn't. Good on WeMo for letting folks who don't need three-way support save a little bit of cash.

The direct, bridge-free connection to Siri brings the standard WeMo Light Switch in line with the WeMo Dimmer and the WeMo Mini smart plug, both of which already offer the same thing. The new switch also gets a subtle design refresh that better matches the WeMo Dimmer.
