It's exactly what I'm looking = > for. Thanx for the link. I also have a couple of the spiderplant boxes, and 12 probes scattered around the house. Over the last 4 or 5 years, I've accumulated more than 6 million temperature measurements in a MySQL database. What I would do today is continue to use the Dallas Semiconductor temperature probe devices and just drive them from the Dallas = 1-wire to RS-232 serial port adapter. You'll need some additional software to discover, address, fetch and convert measurements from each of the probes as compared to the Spiderplant box. = As far as software, you can start with /usr/ports/comms/mlan or /usr/ports/comms/mlan3 to talk to the adapter. louie
