I suggested that a while back. But I admit to being a total noob. I was
looking at the MCP23017. I saw it on Boxall's site here:

I purchased a couple of these a while back. When I started playing with
Arduinos. Never got to needing them yet.
Like I said, though, I'm learning more just listening and watching you guys.
Dave, I learned some by putting together your Si570 board. Kind of like a
foggy day when the sun starts burning the fog off. Things are getting
clearer all the time. Ha, ha!! :-)
