I decided to try a Harmony 650 universal remote after reading reviews and some posts here. Could not get it working properly and their phone support was no help. The setup was pretty easy - connect it to a PC and run the setup program - but it just didn't work properly. It [SIZE=12pt]would not control my Roku 3 at all. The Roku 3 worked fine with its own remote, but would not respond in any way to the Harmony - none of the buttons worked. When I selected the Roku 3 on the Harmony remote, it was controlling my older Roku HD, while the Roku 3 was completely unresponsive to it. I tried the "Add or fix command" option in the program, but it had no effect. The Harmony remote wouldn't even acknowledge that the commands were received. [/SIZE] [SIZE=12pt]The phone support agent couldn't do anything but walk me through the same stuff I had already done, configuring and re-configuring the remote, but it had no effect. He did have me try removing and re-adding it to the configuration, but it made no difference. [/SIZE]At one point, he suggested I just use the Roku 3 remote instead, which is ridiculous, since it would defeat the purpose of using a universal remote. I was able to control my DirecTV HR54 with the Harmony, but some of the buttons I use weren't pre-configured - the SkipForward, SkipBack, and Mini-guide buttons. I used the "Add or fix a command" to program those buttons and this time the Harmony gave me the "Command received successfully" response for each of the buttons. After syncing it again, I tested the remote, but those buttons still didn't do anything. I finally gave up and sent the Harmony 650 back for a refund. Anyone else have a similar experience with a Harmony remote or have any idea what the problem might have been?
