Over the weekend I installed a GE 12727 Z-Wave Wireless Lighting Control Smart Toggle Switch. The install was straightforward and the switch paired with my Almond+ without issue. The problem is that I can't control the switch from within the iOS app. The switch shows up as an On-Off sensor and it looks like I should be able to toggle the lights by tapping the app button but the app ALWAYS shows "Could not update sensor data." for this sensor and tapping the button does not change the state of the switch.
FWIW, I can toggle the switch from the A+ LCD screen and it seems that the LCD is showing the correct status (although I did not look at this very closely). Also, I have added the switch to a scene and that seems to be working as expected.
Not being able to easily control this switch from the app makes the switch much less useful - to the point where I might uninstall it and try a different switch if there is one with better app support. If I can get this working I have plans to install three or four master switches and several add on's as well.
Hopefully this is on the radar as something that can/will be fixed.
