We've changed the behavior of our Alexa Smart Home skill when used with Schlage/Wink and August Smart Locks.
Due to a request from the Amazon Alexa team, we have disabled the ability to unlock your lock via Alexa when that action is included within a Routine. This change went in to effect on December 24, 2016.
Routines that contain unlock actions will continue to work, but the unlock action is not run when triggered by Alexa. Lock actions continue to work as expected.
We plan on revisiting support for this functionality once there are better means to limit access to security devices via your voice.
If you have any questions or concerns surrounding this change, please feel free to contact us.
