Glad to hear that, 'cos I agree 150% - this is absolutely an essential
building block to anything that purports to be an "intelligent"
home...
I would dearly love for someone to come up with some detection technology
and some methodologies for deploying them that would enable occupancy
detection do be done both reliably and economically... Glad to hear that
you're up for the challenge!

You're lucky in that respect then, that should simplify the logic somewhat.
- Not true for all of us though... :-(

I agree you definately need to employ at least 2 different detection
technologies for this, - there is NO single detection technology that is
available today, (to the likes of you and me), that has been proven to be
able to do it reliably... (IMHO)

OK, fair comment! - you've got me on that one!
