This is basic functionality, done by most alarm systems. Should be simple, as we can already tag the different sensors, we should be able to hear a specific entry point as opposed to just a chime.
Since the Ring keypads and chimes will not verbally announce which contact sensor or motion detector is being tripped, I have programmed my Echo system to make the announcements for me. You can do this by building a Routine for EACH sensor and EACH Echo. I currently have 7 contact sensors installed and 6 Echos. I had to build 42 routines to allow each Echo to announce which of the 7 contact sensors were tripped. It is not an elegant solution, but it works.
