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
