"It works, and has two configurators, basic and advanced"4.0 starson by allan_vancouver
Pros: Windows and Mac OS support, plus Firefox support.
Logitech Harmony Remote 7.7.0 software has significantly more function and flexibility than the default online setup. Good enough for my modest needs.
Cons: Documentation didn't indicate that Harmony Remote Software 7.7.0 was a downloadable alternative to the default "simple" online configurator. Backlight and a charging dock would be nice, but not essential for me.
Summary: I tried the more "advanced" Acoustic Research XSight Touch AARX18G for an hour or two and gave up because the software would not work. I know the Harmony doesn't have a touch screen or backlight, but what good are these features if you can't even set up the Xsight. I exchanged the devices at the retailer and the Harmony worked correctly the first time. I did switch to the more feature-rich downloadable Remote Software 7.7.0 after first trying the default simple setup, because I wanted to rename the Activities (Logitech could improve their documentation included in the box so buyers could make a choice up front). Logitech's huge online database of devices included all four of my home theatre units (Z550 amp, Pioneer Elite BD DVD, Octava 4X1 HDMI switch, Epson 8350 projector), so I didn't need to do any IR "learning" from my old remotes. I only had to manually add one IR step to each of my Activities to turn off the LED on my Octava 4x1 HDMI switch. I may try to work with my Logitech Z5500 audio amp settings to see if there is a discrete "power on" and "power off" instead of an on/off toggle, because sometimes it gets out of step, especially if you are making configuration changes and forget to do an "all off" before updating the remote on the PC.
