The most unpleasant was that in some software versions the volume control RECOURSE hang. There remains one ever had the heart and are you anxious about his conditioning.
The Harmony 1100 is faster and has a new GUI (Graphical User Interface). When you set up I was extremely surprised that I was able to set 1100 NOT with my existing account Logitech Harmony. I was linked to a new account set up and then it could go.
When Harmony can now much more intuitive and configure. The key bindings are much more apparent.
The keys can be stored now graphics. That's a significant advance.
The black surface would have been able to save because it is much more sensitive to dirt. Probably the marketing has willed it so that the customer also sees that he has a new remote control.
Otherwise, technically speaking from the outside is all the same.
Why now should be "off" beside the off button is unclear to me. Obviously, customers have complained that they do not know what the "off" symbol means :-)
However, the extremely high increase in prices for Harmony 1000 is inexplicable to me. The hardware seems to be twice as good NOT. The software is of course much better.
The fact that you have to make for a Harmony 1100 its own account, I guess, that the Harmony is 1000 not updated on the user-friendliness of 1100.
Last but not least is my criticism of the RF Extender. With every update the settings on the main remote control, the RF Extender has to be updated. Even if you just exchanging graphics. Since the updated software should be intelligent. The additional update of the RF Extender (So you can, for example, also control IR devices in cabinets or utility rooms) requires a pull of the power supply from the RF Extender. Since my system is installed in a cabinet in which to get difficult at the outlet I must climb each and seals to pull the plug and plug it back later. Since you should make a on / off switch goes into the RF Extender a try. Alternatively, a ductility of the cable directly on the Extender would be a solution. Since the cable is unfortunately welded.
