Do you have a lock that can be operated remotely (Z-Wave or ZigBee)? Are you looking to only detect when someone pressed your bell then you’ll need a sound detection sensor which aren’t as reliable since it can be false triggered. You could just buy a Z-Wave or ZigBee button and place that on your front door and then use a simple app like this to trigger notifications to you or you can use something like CoRE or WebCoRE to create more complex rules like you mentioned to automate your setup.
