| Energy Monitor |
Real-time Electricity Monitoring
updated once every minute. We were consuming about 10.000 kWh a year, way to much! For years I was thinking about a plan to
measure the electricity automatically. With this little project I was able to reduce the electricity
from 10.000 kWh to 6635 kWh. Because of the accurate and minute by minute reading of electricity consumption I became much more aware of it all.
I found out that I was consuming 0.600 kWh at night! With simple things like
unplugging adapters of my cellular (GSM) and kill standby of the harddiskrecorder, computers and television I was able to reduce the power to around 370 Watts.
I also discovered that there are a lot of power adapters which consume a lot of energy with doing nothing, so I use now switching power adapters which have a high performance and so consume much less energy. The energy monitor is
automatically plugged in my Home Control System which adds nice little features like for example getting a mail on your cellular (GSM) if the power consumption is higher then
500 Watt and there is no one at home.
I really think automating your home or business and
controlling your energy can help to reduce the worlds growing energy problem.
I still use more energy then average but this is mainly caused by the Bwired Webserver
which consumes 65 watt incl. noBreak 24/7 (old server 130 watt).

| Real-time Electricity Counters |
| The Real-time electricity counters below are
updated every hour. The Right one is the night counter (night-rate)
and the left on is the
day counter (day-rate). The counters are exactly synchronic with the counters of the power company,
so we don't have to write it down!

 How is it Done?
|
| Real-time Electricity Monitoring
A infrared-sensor is optical connected to the flashing led on the electricity meter of the power company and reads the total consumption
we use. The led on the meter flashes 480 times for every Kilowatt (kW). The pulse is counted with the RFXmeter from RFXCOM and
once every 30 seconds my home automation system receives wireless the amount of pulses (led flashes) counted. All the data is saved in a SQL database which I
can query and display on the webpage's. If you want the exact schematics click on the link above or on the image below.
