Hey, I care about 3 watts it is those little 3 watt items that can leave me in the dark!
Yup. And if you have lots of 3 watt items, it really adds up.
Here is an excerpt of the items I want to turn off when I'm not home and their standby wattage :
- 4 battery chargers that each use between 0.3 and 1.5 watts idle. I am thinking of putting them on a power strip, controlled by a module
- shredder uses 1watt when idle. Clearly doesn't need to be on when nobody is home !
- Brother MFC-9840CDW networked laser all-in-one uses 27.6 watts when idle . This has a clock, but it's not critical. Too bad it doesn't have built-in NTP client. The savings from having this turned on/off will be big.
- D-link wireless router uses 6.4 watts. But I'm not going to turn this off, I already have some internet monitoring for my solar system. And I plan to have remote x10 access.
- cable modem uses 5.9 watts. Again won't turn this off due to the solar monitoring. And I plan to have remote x10 access.
- HP LP3065 30" monitor still uses 5.8 watts idle.
- Ooma hub uses 7 watts idle. This provides my telephone connection. Right now it's hooked up between my modem and router. It could be hooked up after the router and turned off when I'm not home instead. Not sure.
- Panasonic cordless phone base. Uses 1.5 watt.
- 5 Panasonic handsets throughout the house. Use 2.5 watts each.
- Roland VS-3100 Pro mixer . Uses 10.6 watts idle. Already have this on an x10 wall switch.
- M-Audio BX5A speakers. Use 8.9w idle x2 . Already have this on an x10 wall switch.
In the home theater, tons of things have idle standby power.
Trendnet gigabit switch 2.1 watts.
Polk subwoofer 6.6watts
Yamaha receiver 2.2watts
Boston subwoofer 8.5watts
HTPC (Asleep) 5.5 watts. Can't turn this off or it won't record.
Dish 722 DVR . 50.7 watts !!! Can't turn this off or it won't record. The power usage from having this on standby is about $15/month, vs the $55/month satellite service bill.
Yamaha DVD changer 0.3 watts. I can still turn this off if hooked up to a power strip with a bunch of thing in one x10 module.
Sony SACD changer. This has a front power switch and not remote controllable for power. 0W standby, but 16.4W if front switch is left on ...
Yamaha Cd changer. 7 watts standby. Clearly never needs to be on unless I'm home.
Channel master antenna amplifier. 2.9 watts. This needs to stay on or the DVR and HTPC can't record OTA signals.
Zektor audio switch. 3.5watts. Doesn't need to stay on.
Simple Tech Hard drive. The power supply uses 5.7 even if the drive is off!
HDMI switch 2.9watts. Doesn't do anything unless I'm watching.
x10 ir543 receiver . 0.9 watts. needs to stay on
20+ air wick warmers throughout the house. 2.5W each ! And I thought the oil cost for these was the main cost. But actually power is just as bad. And it still drinks power even if the oil is out.
washer and 110V gas dryer use 1.6watts each. No clock in those. It still makes sense to turn those off together via x10.
3 Roomba chargers that take 3 to 6watts standby each. I have to allow for enough time to recharge the roombas, so not sure how long I want to turn those off. These might be good candidates for timers.
toothbrush chargers use 1watt each whether the brushes are on it or not. Probably not worth controlling.
sharp microwave takes 1.6w idle just to keep the clock. I don't know why I need a clock on a microwave. Timer yes, but clock ?
And the list goes on. It took me a week to go over everything with a kill-a-watt. There are still a few things I haven't measured like the 2 garage openers on standby (which I may not want to turn off, anyway - but thinking about replacing because they have no built-in light when opening). I also couldn't measure several hardwired appliances either with the kill-a-watt. I may need to figure out the standby usage them using the smartmeter and turning off some breakers and seeing the difference.
All those things may look small by themselves (except the printer), but they actually add up to hundreds of watts. I have accounted for 642 of the roughly 800 watts of standby so far in my spreadsheet. I might end up turning things off selectively with 20 to 50 appliance modules throughout the house that use 0.4 to 0.5w each. It would still be a huge savings.
