If you’re using the Enhanced Z-Wave lock device handler then you can set custom actions for Keypad and Manual unlocks (and locks) using LUM, RLA, LM API or any of our other lock and user management apps. You can have it turn on / off switches, changes modes and more when it unlocked via a keypad or manually (for each user individually or for all users)
If you want it to trigger an automation, an easy way to do it would be to configure LUM, RLA or any of the other lock management apps to turn on a virtual switch when opened manually or via a keypad, and then have an automation monitor that switch and run a scene if it’s triggered (and also reset the virtual switch to off).
