I also have the problem that i always have to repair my smart control with the pc.

To do that i have to start the harmony app on my android phone, click any key and then click on "Pair".
After doing that the Logitech Harmony Remote Control works well with the PC otherwise it doesn't work at all.

Does anyone else also have/had this problem?

if you're using openelec make sure you're selecting trust and connect when you do the pairing. there was a problem where openelec before 4.1.6, i believe, would not re-pair properly so if you're on an old build like that you should upgrade.

Thanks for your quick reply!
No, I'm on Windows 8. In my Device Manager it shows up as "Logitech Harmony Keyboard" and belows stands "No Drivers found". There are also 2 Bluetooth Devices which aren't installed properly.

But usually this should work out of the box without the need of an extra driver, shouldn't it?
