Did this problem get solved?
I ask because I just installed one of these things. It paired just fine, once I realized that I first had to execute the counterintuitive step of deleting the sensor from the Almond+.
Once paired, I moved it to its final location and hooked it to a light.
It seemed to only respond to about 20% of attempts to dim or brighten the light, and when it did work the Almond+ iOS app would still sit there waiting a bit and would then report that it couldn't update the sensor (which was the same error it would display when it actually couldn't update the sensor). I tried using the switch closer to the router to see if range was the issue and had the same issue, but it's possible that it was still too far. But it did seem very odd that sometimes the switch would respond to my command even though the Almond+ app said it wasn't able to update the sensor.
On a different note -- does it strike anyone else as weird that on the Router's LCD, the interface for this switch includes both a dimmer and on/off buttons, but in the router's web UI and in the iOS app only a dimmer slider is available? Most of the time I plan to toggle the switch completely on or off, so would like to have a binary toggle in addition to the slider.
I'm on R070 firmware and am running the latest iOS app. I think I only have one other z-wave device on my network, so I don't have much of a mesh going.
As an aside, it'd be nice if the Almond+ router's admin web page would list the protocol used by each sensors, not just their name and type. It'd be nice to look at the list and know what's zigbee, what's z-wave, etc. Not essential, but it'd be nice.
