Which model?
Up until now, the Samsung smart locks (which are made by a different division than the Samsung Smartthings Hub) were Bluetooth devices that did not work with SmartThings.
However, it’s possible that with the new V3 app, they might be compatible. They’re definitely nice locks, but it’s unlikely that people in this forum would have one since they didn’t previously work with the platform.
There are also a few Samsung SDS Zwave models, but only available on the Korean zwave frequency, so again, people in this forum would not be likely to have those.
