Monitor exisiting inline high voltage limit switch

I have a roller door with a built in up & down limit switches that I’d like to monitor in HA.
The door controls are all 230V mains voltage (I.e. there is no low voltage control circuit)
The limit switches are NC and open to kill the circuit and stop the door.

What is the best way to monitor this in HA?

A standard reedswitch door sensor and a magnet on the bottom of the shutter.

Beyond that, there’s too many variables and safety issues to tapping into an existing high-voltage system. Many have the motor and limit microswitches in a tube within the central drum, so are horrible to service at the best of times.
