These will likely be coming in 2016 because many of the HomeKit receptacles are going to be of this type. Right now though, I don’t think there are any that are compatible with SmartThings.
Jasco just certified a new zwave plug-in that includes a USB port, but it’s not even available for sale yet. But they’re definitely coming.
Jasco also just certified three or four new plug-ins for the same line that have 2 z wave controllable outlets in each unit pinstead of 1 zwave outlet and one nonnetworked passthrough. This is another feature that people have wanted for years. Zwave plus makes possible somewhat smaller chips which is helping with this, but there’s no question HomeKit design is also driving it.
Again, not for sale yet, but this is probably the GE line, they should be coming soon.
