A simple photocell could be taped over the LED with Gaffer's tape.  I
have never actually used a photocell, but I'm assuming if you are just
looking for on/off you can probably read this with a Weeder digital
I/O board.  Definetly could be read with a Weeder analog input board.

I don't know anything about the 1-wire interface, though.
