Home Vital Sign Aggregation

After having my friend help me with my recent home inspection, it occurred to me that I'd like to have a lot more data at my disposal about my home. Easy stuff that should be logged: Temperature rise and fall, humidity levels, air pressure (positive or negative), power loss and gain. Some home automation systems do a few items listed, but not all of them. I want to know what happens when I light a fire in the fireplace, what happens to my home when I'm away for a month, what things happen to my home at night. I don't need to be emailed about it (all the time), but I'd like to see all these stats on a secure website. It's more than just electrical usage, but it certainly includes that as well. It's about knowing what kind of shape your house is in, the current fitness of your dwelling. It's probably a $500 item, with a bunch of good sensors and a USB connection, but I'm not the engineer nor marketing guy. Should come with all new homes, should be subsidized by the power company, yo.
