Hi, I want to create a button that if any user interact with it first, will automatically disable the same button on other user’s app (I don’t know if that make sense)
Specifically speaking, I want to create a lock/unlock button for a smart doorlock project. If the user1 press the lock button, then the user2 will not be able to press the lock button until user1 unlock it back.
Is it possible to do that? Any solution, link or aia that is relevant to my topic is very much appreciated.
