I went into the template for the TV and manually added the On/Off command group, and now I have all the functions that my USB-UIRT can control available in the advanced wizard drop down. However, it did not work on a "Test Code" press of the button in the webadmin.
I have a question: Could this be because I have "Ignore On/Off" set to "On" in the advanced page for the TV? This seems like the most logical answer, but I am not sure, as if I turn this to "Off" then every time I exit media, the TV turns off as the last command. This was doing this before I made any changes to the template, and has been the result since the day I installed LMCE.
Does this new ability in the advanced scenario require that "Ignore On/Off" be set to "Off", and if so, is there a way to make it not turn the TV off as soon as the media exits, and then just continue to do so after the timeout has passed? It is quite vexing, but I am sure someone in this forum has found the "proper" way to get these things to all work in concert.
So to sum up:
I now have the on/off function in the advanced scenario when selecting the TV device for that room.
It does not work.
I have the "Ignore On/Off" set to "on" in the advanced window.
If I set this to "off" is there a way to have the TV not get turned off, after media exits (immediately actually) and still have it do the 5 minute no activity timeout power cycle?
I have not yet looked into the delays. But I will have a look at johndecker's answer at the next opportunity.
Kinda sucks sometimes having a system in production, that very seldom ever gets the opportunity to test things, but that just proves it is a solution that everyone gets benefit out of daily in my home.
