    This might offer a solution for switching the Si570.

      It's a USB Experiment interface board kit offered by Velleman. It has
      8 digital outputs, 5 digital inputs, 2 analog inputs and outputs.

      It may be a little bit over kill, but it's a thought.

      ... It looks like it s made for industrial control, put that puppy in the closet with the AC and wire it up to give your home a really smart heating/cooling

        It looks like it's made for industrial control, put that puppy in the closet with the AC and wire it up to give your home a really smart heating/cooling profile and save a ton of money. Those connectors are not put on cheap boards but they are handy.

        Did you find what CPU it uses, I didn't see it, and more important are the I2C connections brought out? But then there is bit banging.

        Actually the circuit for a small PIC or AVR CPU chip is so simple, take a look at the schematic of the new SoftRock, power, ground and that is it, the rest is programming magic, and even that is not difficult or expensive since so many compilers have a free limited version, but capable enough to pretty much do anything needed.
