Hi there. I need your support. My setup: Amazon Fire TV 1st gen. FLIRC as IR remote Logitech Harmony 600 I don't have this double key issue. Everything is working fine. But one problem I have to solve. How can I get de FTV into sleep mode? If I press the matching Homebutton longer (2 seconds) I can see on the harmony display only a short signal. Any ideas? Thanks.
