Bummer you didn't get it working as they really are good devices. If your Fibaro one works for you then no big deal. I did manage to get mine working correctly including reporting power usage (had to set some of the parameters manually before it would do it). I have mine working well both on/off/dim via wall switch (using Clipsal Saturn bellpush). Also managed to get it set so it would show the device being on/off when turned on by the switch. Default settings didn't have that enabled strangely.
