... Requirement however is an absolutely stable wireless !!!
The mentioned in other reviews, I had problems with a Fritz box and with a simple TP-Link routers also. With the change to an Apple Airport these have completely disappeared, along with other hardships at z. B. AirPlay.
If the connection is stable, the remote control is working properly and very reliable. Even switching between app and handle works perfectly, so changes by hand part are in the app also tracked. The enclosed IR additional transmitter is with me in spite of installation in a rack shelf, without line of sight to all devices, not necessary.
Biggest improvement to its predecessors is the conversion to the MyHarmony software. It is much easier to handle when it comes to setting up the equipment, and especially the fine tuning "on the spot" with the app is a huge relief.
As years of Harmony fan, I'm sure not very open mind, but also without radio function, the Wi-Fi system surpasses me anyway, that's the best multifunction remote that I had previously. The Harmony 900, then to 4 times (!) Buy price, since you can not keep up. Other manufacturers (Philips, Sony, ...) had disqualified earlier.
I would buy the SmartControl definitely be back.
