Does hardware platform matter? If not a very inexpensive alternative set is found on Adafruit's site for the Raspberry Pi and FreeBSD can easily talk to either some of the options directly or a cheap ($10) 4-channel 12-bit analog board. I am using this approach with the Pi2 as a pool controller with multiple temperature inputs and drive (through a relay board) to handle both the VFD-controlled pump motor and valves, plus spa heater. -- Karl Denninger k...@denninger.net /The Market Ticker/
