Hi all,
I have a yamaha preamp, that has only a single power button. (No separate on and off buttons.)
So, I would like some kind of inexpensive way for homeseer to know if the device is on or off, but I do not want to plug the unit itself into a x10 module or any other module.
I do not know if the audio/video rca outputs have any voltage running through them when there is no signal running through them. In order words, last time I used the preamp I was watching and listening to dvd, but now I just turned the preamp on, but NOT THE DVD PLAYER. So the preamp is on but there may/may not be signal through the currently selected preamp input (DVD). Perhaps someone knows if there is some low background voltage regards of output signal.
The other possible ways to monitor might be-- there is a switched and an unswitched power outlet on the back of the preamp. Perhaps using the switched outlet with some sensor that might be the ticket, but I don't know how. When preamp is ON switched outlet is always on, when preamp is OFF switch unit is always OFF.
Finally, I think there was some x10 magnet sensor that was a ring, and went around the power cord and could sense the magnetic field changed for on and off, but I don't really know anything about it.
Thanks in advance for your suggestions.
