cheers for the link, but I need to monitor electrical consumption at the same time, and was also wanting to monitor solar irradiance, air temperature and wind speed.
I have the ability to do most of that already, just not to be able to data log it all in the same data logger.
Well, I might have, just need to find time to try to cobble it all together, and it involves removing the kit from our solar water heating system.
Should have it installed in the next few weeks I hope, got to get it in for at least part of the winter.
You could use the openenergymonitor.org system with emoncms for the display/logging function, (Emoncms ) and using emontx or various jeelabs/jeenode modules collect all the data ffrom the various sources, it would take a moment or two to work out the configuration, however most of the programming has been done, you just need to hook it up with the appropriate sensors. - Here's a raspberry pi hooked up to a maplin wireless weather station: Worcester Renewables - Live Weather Pages - Powered by Raspberry Pi logging data every 5 mins to the met office and wunderground.
