With my current remote, Harmony 300, I find that, occasionally, when I turn on the system, the TV does not properly receive the ON command. Maybe I'm just lazy in my pointing style, maybe the emitter is a bit weak, maybe it pauses between sending signals and I put down the remote too soon. Whatever the problem, I do find myself with the TV still off. The H300 is device oriented, so it's pretty easy to press the TV button and turn the TV on.
How difficult is it, on the H1, to go to device mode and turn the TV on? Will the remote get "confused" about the state of the TV?
your TV (or any other device) supports discrete power commands (and you setup the remote to use them), all you have to do to correct and re-sync the power states is to hit the Help button... the first thing the One does when you hit Help is resend all discrete power and input commands. It does not re-send toggled power or sequential input commands because this can screw things up worse than they probably are.
If you have devices that use Power Toggles, the Help button can still correct things... after you hit help and it resends the discrete commands, it will ask you if that corrected the problem... if you answer "No", it will begin a series of questions about each device until it determines the problem and corrects it. This works fine for casual users, but I find it rather tedious to go through all the questions when I know what's wrong and how to correct it.
The only device I have that does not support discrete power is my cable DVR. I have programmed the typically unused + key (to the right of "0") as a DVR power button in all activities that use the DVR. This allows me to fix an obvious problem without playing twenty questions with the remote or entering device mode. You can program ANY button in an activity, hard or soft, as your emergency power button (well... not THE power button, lol). If I was unlucky enough to have several non-discrete devices in an activity, I would add a "Power" page to the custom buttons that had all of the necessary power buttons in one place.
BTW... if you use ANY means other than normal Activity startup/shutdown to change power states (e.g., OE remote, Device Mode, custom power buttons, etc), the Harmony will lose track of power states. However, if its already out of sync because your dog walked in front of the remote at the wrong time, then all you are doing is manually re-syncing things.
