</div>Why do you want to turn it off? I seem to recall reading somewhere that most STBs draw the same power when on as when off,<br>
perhaps a fraction of a watt less, but essentially the same.<br>
<br>
The cable companies want to be able to address the box whether you have it on or not, for one of their innumerable channel<br>
lineup changes or to make other "upgrades".<br>
<br>
I'm not sure if this is true of satellite receivers or not.<br></blockquote><div><br>I've seen the same thing with my DirecTv H20 with a kill-a-watt. It draws ~40-42 watts, with barely a detectable difference when the box is "off". I suspect there's multiple reasons, ranging from calling home, to updating recording schedules remotely and actually kicking off scheduled recordings. The only real difference I've seen between on and off is that the live tv buffer isn't recording when the device is off.<br>

You might want to look into whether it makes a difference in your case or not, it might not be worth the effort.<br>
<br>
I would assume you could send the "on" or "off" code using your channel change script. You might have to put a delay after<br>
sending the "on" code before sending the channel data, to allow it to boot up.<br>
<br>
My DISH VIP722 takes the better part of a minute to boot up, which is why I've not looked into turning it off.<br>
