Hi - I'm looking for recommendations for inexpensive distributed IO boards for home automation. I'd like to monitor and control a few points around the house. I'm thinking of remote IO boards that talk serially to a central control board (or maybe just a central linux box). I've seen a few IO boards here and there, with not too bad prices (around $50 US). However, they tend to have a lot of IO per board. Is there something out there that is even smaller and cheaper? Let's say 1 to 4 IO points per board, connected in a daisy chain. Thanks.
