The Hub is the greatest addition to the Harmony family to date. It's a game changer for the user-programmable remote space, and it's what the Harmony Link should've been. The price isn't crazy, but it's not exactly a great value either. So while we do recommend the Hub to anyone with a compatible smartphone, the solution is far from perfect. First off, we wish it weren't limited to IR and Bluetooth -- but we've been saying that for years. Two-way control options would greatly enhance the user experience, as would a faster and more reliable protocol.
The other item at the top of our wish list is a documented network API for third parties to interface with the Hub. The included apps are great and all, but there are lots of other solid applications out there that could really enhance our home theater experience, if they only had some control over our living room. This would also make it possible for other home automation controllers to integrate with the equipment. So no, this isn't the home theater control solution we've been dreaming of, but at the very least, it's a big step forward.
