Wordpress plugin

Hello there. I am an owner of a small hotel. All rooms have some smart functions (eg. controlling the ac by voice, closing curtains etc).
I have a website that the user has to create an account thru all available ways (custom credentials or registering thru famous platforms such as Facebook, apple etc.) so it can make a booking. I was wondering If it was possible that the user after booking could be granted permission automatically so he/she can control remotely all smart functions thru a ewelink plugin Directly from my website.
