Suggestion for termination of wired alarm sensors

I’m building a new home in the coming year and I’m planning the home automation setup.

All doors and windows will have wired sensors. I was looking forward to using a konnected.io board but since it does not have ethernet that is out the window. I have chosen wired sensors in order to avoid intruders to be able to jam the alarm system with a wireless jammer.

So the question is - how do I terminate the wires for the sensors in a way I can read the state from Home Assistant. The end point and the PI with hassio has to be connected via ethernet.

I would prefer an off the shelf product if possible. Any suggestions?

Not off the shelf, but an arduino board with an ethernet shield, with some mqtt glue.

Or just attach the arduino via usb. It does depend on how many sensors you’re having.
