Not Clear, my bad
I guess I did not communicate well.
There is a tweak (like an app) that adds to the settings menu an option to turn off the backlight (The dimmest possible screen) similar to the option to Auto Lock the iPad. This tweak, known as ScreenDimmer, will turn the backlight off after a period of time. It does not lock the iPad.
My question is: what is the action to turn the backlight back on? Do you merely touch the creen (what I want)? Touch the home button? Do a combination of things?
I use the iPads for home control and they are wall mounted. The power button is not easily available (Home button is) and they are continuously being charged.
Hope this clarifies it,
