Interesting Link mreish. I don't know that monitoring the air conditioner and controlling the windows is top on the opengauge priority list
But certainly I hope we can incorporate monitoring and logging for electric vehicles. We just need to sense the voltage and current going to the motor. I'd be planning on adding it eventually.
I couldnt expand the xarias_v0.1.tar.bz2 (said it wasn't valid bz2) and I haven't committed to using SVN yet (and there was no online source browser), and didn't get anything out of the video, so I cannot speak to xarias. But help yourself to what we have in opengauge and let me know if you want to join in the fun.
