[Sean McGrath, butting in]

I am using a 'temp256' kit from Peter Anderson
(http://www.phanderson.com/t64.html); a PIC based system that does up to
256 DS1820 sensors (and some A/D, DIO) to a serial interface.
http://www.phanderson.com/ is a good source of hardware info and projects.

(for your list, I also have a CPUXA, SEC16, an old X10 TouchLinc (Anyone
else think 'Salid' was promising?))

See http://ee-staff.ethz.ch/~oetiker/webtools/rrdtool/
'rrd' = round robin database. rrdtool stores periodic
data samples, can due computations, averaging, ... and
produces web graphs of the data. It originated from
MRTG, the Multi Router Traffic Grapher,
http://ee-staff.ethz.ch/~oetiker/webtools/MRTG
which is in wide use for network and computer data recording
and display.

I am using rrdtool for temprature recording and graphing and
am working on adding rain and wind. Thinking about recording
electric use.
