I'm sure you can use plugwise for this in the future.
at the moment is RFXcom better solution for what you are looking for.

What's the power consumption of a plug? Plug a plug in a plug to check

Post by **TANE** » Thu Aug 28, 2008 1:29 pm

Plugwise power consumption
Online <0,7 watt
Offline <0,2 watt

measurement is done with a Pro Powermonitoring tool (Digit)

 Are they planning to build a box for in the meter cabinet.
So you can measure a complete fase or 3 fase.
<hr height="1" noshade id="quote"></blockquote id="quote">Yes Plugwise is working on this, would be great to have a Network box instead of the USB key and the possibility to measure on house level like the most of us do.
Only then you have the complete energy consumption control.
They are also working on a small switch on the Circle plugs to manually control the OFF and even more important the ON of a plug.
Lot's of devices can't be switched On And Off by means of cutting the power like Plugwise does. My LCD television for example does not like that.

I found a competing system :

http://www.plogg.co.uk/plogg_zgb.html

available with both british and european plugs
looks a bit more expensive than the plugwise hardware...

but they include a temperature sensor and an Ethernet Access Point and a DLL/API library ?

also each device can be End Device, Router or Coordinator.

I think, for plugwise you have separate circle and circle+ devices ?

Plugs are to big...but..interesting technology.
for Plugwise you need one circle+ (master)
functions of this plug are the same as others.

My server is down to 63W, but that's still too much so I'm thinking about dropping it into an S1 (standby) state with an alarm to wake it up every five/ten minutes. It's running from a USB key; there's no video etc. If a network packet or other interesting event comes in then it will return to S0.

This means the hardware will be switching from S0 <-> S1 hundreds of times a day. I guess this might strain the components - does anyone know how long it will last? Is this going to break it?

My server is using about 75 watt..I'm going to reduce that to 50 watt with new PSU

whats the use of your switches btw? At some point i would go for a 19inch switch (since i have the space and the rack) but thats perhaps to much kwh..

I have few switches
Usage of the 3 Com Giga switch is around 8 watt...thats to much
I will go for some green switches. they consume less then 3 watt
19" versions are for industrial usage mostly they consume lot of extra power and have extra fans for colling +/- 40 watt

(note:12 general-purpose I/O lines and 2 analogue inputs)

the ethernet acces point is simply one of these modules, connected to a Lantronix serial to Ethernet bridge

nice 19 inch for me later, but its bound to be the jackpot..

ziet er goed uit..wat gaat die kosten?
mijn voorkeur gaat meer uit naar een laptop die krachtiger is en minder stroom verbruikt..
ik verwacht dat de prijs ook lager zal zijn.

Okay found another high usage lamp in my house.

It's halogen lamp with 4 X 25 watt G9 socket (25 watt is the lowest)
On e-bay i found some led version that will fit in socket G9...(they are to big)
http://cgi.ebay.nl/ws/eBayISAPI.dll?Vie ... :IT&ih=021

What I'm looking for.
LED
Dimmable
Max size 35mm round
Colour temperature +/-3000K

any tips?
