Another way I used to use is.
Create a virtual switch.
Have smart lighting turn that switch on when door is unlocked.
Have that switch to trigger your routine, or whatever.
Also I'm not sure if @RBoy lock manager handles your lock or makes available the option to use who unlocks the door as a trigger.
I have a Schlage and now use his software to do what I want when a specific person unlocks the door. I used to use this to change the mode when unlocked via keypad . I don't remember if it can trigger a routine or not.
You can also go the CoRE route mentioned above. It's a steep learning curve. You can usually get help when your stuck. It has its own section in the forum.
Hope that helps get you in the right areas or find what you need.
