Notify Unlocked

I’m a senior and I live alone. In the case of an emergency I would want to unlock my door for emergency responders. For this reason I have disabled the auto lock function. However, If I leave the door unlocked, or forget to lock it, I would like to be notified. Can a smart notification be made that would notify me that the door has been unlocked after a certain amount of time, something like 1/2 hour?
