I have the newer shield model , I then learned the shield doesn't have IR sensors so I looked into purchasing a FLIRC to solve this issue. I managed to get everything working and its awesome using the Harmony but I had 2 issues, the remote wouldn't wake the Shield up but I managed to solve this on the Harmony by making a command that hits the "back" button when it turns everything on which wakes the system up by hitting a button.
My issue though is the remote won't put the shield to sleep, I don't see anything on the FLIRC or Harmony and even if I click on "power off" it doesn't do anything.
I was wondering if anyone had similar issues and found a solution? It's not a huge deal as everything else works and the system goes to sleep after 20 minutes anyway. Though I thought I'd ask and see if someone has a solution anyway.
Save yourself a lot of head ache and find a Harmony smart remote
It will save you way more head aches than you can imagine.
