How can I wire an Echo into my mother's nurse call system?

Episode 1463 (1:59:18)

Judy from Virginia
Amazon Echo Dot

Judy wants to know if her mother, who is in a nursing home, can be wired in to call the nurse outdoors. She can't pull the string to call the nurse. The chatroom says that Amazon has the "Add a motor drapery motor" that could maybe do it. But Leo says that the easiest thing to do would probably be to buy an Echo Dot for the nurse's station. That way her mother can do a "drop-in" with the Echo to call them.

The chatroom found this solution from hackster.io. That could work, but she'd need to build it and it would cost a few hundred bucks.
