i’m looking for a solution to connect wired door and window sensors to openhab. I currently use Z-Wave and IP network as an interface to openhab. Approx. 100 inputs are required, so please no solutions for only a few inputs.
How did you solve it?

Have you considered a multi IO board that uses the I2C binding?
(This is just an idea, based on a Google search for “24 channel Multi IO”)
