I just added two new 2477 dimmers to replace two older ones.  ISY found the two devices, added them, then I did a "replace with" to replace the two old devices with these two new devices.  All of this appeared to work.

 

Then I tried to move the two devices into the folder they belong in.  The one device worked fine.  The second device failed to move.  I then tried to query it and control it.  I either get no response at all from ISY or it says request failed.  I tried rebooting the admin console a couple times with no affect.

 

What gives here?

 

The device does seem to have been properly programmed as it does control and respond to scenes.

That's unusual. Try Restore Device followed by Write Updates to Device.

I actually tried that already, but again. . . ."request failed"

I solved it by

 

1) Rebooting ISY

2) Restoring Device
