You can get these working but it was a real pain and I eaily see why there are so many refurbs cause people give up on the terrible software and return them.
I got a pair of these year ago. Worst config software ever. Have to use a Windows system with online connection and a working Silverlight install to generate and download the config. Additionally you have to dedicate 1 email address to each remote to save the configuration.
The Silverlight software was really buggy and ended locking out 2 different addesses I tried where it would keep erroring out on the download. Multiple tech support tickets could not reset or release the addresses. I ended up using invalid fake address to get the profile to generate correctly.
