Thanks so much for making the switch to our new Alexa Smart Home Skill for Sesame! You can now add multiple Sesames to Alexa and unlock as well as lock and request status for each one.
Currently it's not possible for us to add Sesame being locked/unlocked as triggers in the Alexa app, but we hope the Alexa team will implement this in the future. In the meantime, you may want to check out IFTTT which does allow us to make Sesame being locked or unlocked available as triggers. Hope this helps! - CANDY HOUSE
