Thanks. It's not necessary to use the PowerSave plugin with SrvrPowerCtrl, though I do.
If you have SrvrPowerCtrl's "Power-off attached players" feature enabled, then SrvrPowerCtrl asks SqueezeCenter to turn off the players just before it shutsdown/suspends/etc. the system. The players do indeed get turned off. So, yes, feature helps you reach your goal. But according to my Kill-A-Watt meter, there's only a one watt difference between a SB3 that's "on" and one that's "off. My SB3 draws 5 watts when on (playing or idle), and 4 watts when "off." Since it doesn't measure tenths or hundredths of watts consumed, who knows exactly what the difference is. If you live off the grid, where every milliwatt is precious, this 1 watt difference may be meaningful to you. Or, if you think of it as 1 watt x 20 hours x 365 days (assuming that you play your player 4 hours a day on average), then that's, what? Around 7 kilowatts saved per year? I think that's about the equivalent of skipping three showers over the course of that year. Moral of this story? In the future, if we're collectively going to get serious about saving energy, we're going to have to get serious about new deodorant technology. SrvrPowerCtr's "Power-off" feature is really there for the benefit of IRBlaster and PowerCenter. On my system, I have PowerCenter configured so that whenever my Transporter gets "turned off", PowerCenter fires off an X10 command to turn off my two big power amps. That's why I'm using PowerSave too: I have it configured to turn off the Transporter (and thus the amps via PowerCenter) after 20 minutes of idle time. Then I have SrvrPowerCtrl configured to suspend the server after 45 minutes of idle. The fact that SrvrPowerCtrl "re-turns-off" the Transporter most of the time doesn't harm anything. The amps just stay powered off. So, unless you are using IRBlaster or PowerCenter to power down other equipment, or unless that 1 watt is important to you, PowerSave serves mostly a cosmetic purpose: you get a nice clock to look at without having to reach for your remote. Or if you have your "off" brightness set to 0, then you'll (I think) save on the longevity of the VFD display. -- gharris999 ------------------------------------------------------------------------ gharris999's Profile: http://forums.slimdevices.com/member.php?userid=115 View this thread: http://forums.slimdevices.com/showthread.php?t=48521 _______________________________________________ plugins mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/plugins
