Interesting how so many people are starting to hack their homes for energy consumption, etc. I was wondering if you have some information about the accuracy and frequency of measurements made by the CurrentCost monitor. Am currently tracking power and gas meter revolutions and wondering what the differences would be with direct current sensors…

Yes, as others have said, the fridge is a likely candidate for the peaks. You could turn it off for a few hours to find out.

Hello!

I don’t know if you managed to get your gas consumption online already. I have a llittle setup that allows me to do that: the gas meter has a reflector number (usually the 0 or the 6) which can be used with an optocloupler to measure gas consumption. Let me know if you want some more details.

Current Cost Monitor…

A couple of guys at work have managed to lay their hands on a funky new device called a Current Cost meter. It’s pretty simple to understand, it measures your household electricity usage and displays……

the blips could be from the fridge/freezer, apparently they do blips

some things i like about this are:

1. i can be alerted via phone when the kettle is ready, as i don’t hear it, by getting the computer to look for the edge at the end of a 2kw blip

2. i can be also alerted via phone when the oven’s ready, there’s the straight line while it’s heating up, but then we have blips when it’s trying to stay at the desired temp

3. with my GPSed phone, i can be alerted when i’ve left the house and the iron switched on (happened twice already!) by putting the two together

4. as my hot water comes from electricity (currently), it can also warn me if i’ve left the water running in bath for too long by looking for the short blips pattern

very useful implications from this simple device.
