since i`m new here, let me first introduce myself a little bit:
i´m a computing/linux enthusiast from cologne/germany with some affinity to electrical engineering, energy and environmental protection, too - so it looks that flukso is just the project i was always waiting for :) . i have just come across this site via wikipedia article about home energy monitors.
i have spent some time with with currentcost envi , with good results. i like the envi very much. see http://umweltsuen.de/envi-demo-static/ for my home-power graphs.
what i´m absolutely curious about: energy monitors like currentcost, owl, efergy, wattson, flukso .... are mostly unknown in germany and there is no market yet, whereas in UK already 1 million ENVIs have been sold. i have asked some suppliers of green energy if they thought about selling energy monitors or giving away for free, like in UK, but they all gave negative response. looks like a conspiracy to me... :)
currently, i`m searching for a way to have long-term & detailed logging capability without need of running a home-server or flat-rate internet connectivity. for example, i would like to put an envi in my parent`s home to be be queried via PC from time to time to show those nice graphs like those i`m currently logging via my home server.
i have set sort of an hurdle for myself:
that system should all be as low-cost as possible, as i think everybody should have such a power monitor with detailed logging capability and that should go well below 100 Euro.
so far, i have these little projects:
- hooking my envi to my home-server and creating graphs with rrdtool (this is in production for ~1 months now and works very well)
- adding openwrt kamikaze to netgear router, reading currentcost envi data and storing on usb-key, to be served via embedded webserver. basic tests look good. nice: you can hook the envi without usb2serial converter directly 1:1 to the board - just plain low-voltage ttl. problem: without internet connection, there is no timesource. so, running this standalone without rtc sucks, as you need to set the time with every power-loss.
- put linux on old compaq evo t20 thin client and run rootfs from usb-stick. have made some progress. what`s nice is that you can easily mod the t20 for having rtc working and you have 4 usb ports. problem: evo t20 still draws too much power, imho (~8W)
- creating a list of available home energy monitoring systems
so, having some device like fluksometer looks interesting and i`m curious if there is a way to run this without internet connection.
even if this will not be a planned feature, this is an interesting project. ( i also had a look at the fonera router for being a candidate to attach a currentcost to....)
