Yes, the Ring Alarm Contact Sensor requires a Ring Protect subscription to get instant mobile alerts when doors and windows open.
The sensors themselves work with the Ring Alarm Base Station, but the notification features that alert you to activity require an active Ring Protect subscription, which is sold separately.

You do need to buy a z-wave usb stick to connect the sensor to home assistant.
