Has anyone done this in STR? Am I too optimistic on this strategy

[Leo Poon]

This could be a unique scenario on STR. I have come across an opportunity on a real Bed and Breakfast but with no breakfast served, and it has been running as Bed n Breakfast for the past 10+ years. The property has 5 bedroom units, each with a private bathroom, with 1 of the units being an owner quarter. Everyone will share the living room and kitchen.

Now I want to automate everything. I am thinking to install a wifi smart lock on the front door, so guest can come in the front door with a digital code. Each bedroom unit will have a door tag number from 1 to 5, and I plan to install wifi smart lock on those bedroom doors as well, so guests can self-check-in according to each door tag number and the digital code I send them. The code will expire when it is time for them to check out. Then the cleaning company can come in and get the bedroom unit ready for the next guest. I intend to automate it out of state.

Have anyone done something similar where you install wifi smart lock on the front door and the bedroom door? It's kinda a new twist to the old Bed n Breakfast model. Love to hear all the suggestions and comments. And a big thanks for @Lucas Carl for answering my questions!
