In case anybody is interested, I have figured out how to turn off the Shield TV with Harmony 650+Flirc (or more precisely, put the Shield TV to sleep.) Yes, I'm THAT OCD about keeping my power bill down (not to mention keeping my house cooler in Phoenix summers.) What you'll want to do is tell your Harmony that in fact you do want to control the power of your Shield TV, and then set the Flirc to recognize your profile's power off button. Different profiles have different defaults in this regard, and I know people use different ones, so I'm just going to tell you how I configured mine: 1. I used DanVM's instructions (found here), only I used Flirc XBMC profile (when I chose it, MyHarmony called it Flirc Kodi) as my beginning template and renamed it to Shield TV. 2. In the MyHarmony application, Under Devices > Change Device Settings > Power Settings > Next > I want to turn off this device when not in use. > I press the same button for on and for off > Next > +Add Command > Under the dropdown menu, select PowerOff > Leave everything else default and click Finish 3. Open the Flirc application > Controllers > Media Keys > click the power icon button. 4. On your Harmony remote's LCD screen buttons, go to Devices > Shield TV (or whatever you named it) > Power Off. (If your flirc application says 'Recorded Successfully', then it worked, even if it suspended your PC.) Done! Connect your Flirc to your Shield TV and your harmony remote should turn it off as expected. Ideally, somebody could pester logitech (I don't know how to contact them) to add a Flirc + Shield TV profile that effectively does everything I mentioned above. Here are some things that I wish we could have but probably can't ever have: - Universal 8 second back / 30 second forward buttons that don't bring up the playbar overlay - Universal subtitle toggle button (for those moments when you're not quite sure what the person is saying) - A way to use voice search without having to reach for the Shield TV stick remote (By universal, I mean works on every app) One can only dream, I suppose. Nonetheless, this works really well, and I have to say that the Shield TV is the best STB I've ever owned (you really can have it all with this thing; netflix, amazon, youtube, plex, kodi, hbo, Dolby TrueHD, DTS-HD, emulators, all on a very speedy UI) and Flirc makes it even better.
