There is no official integration for Chamberlain MyQ garage openers with SmartThings. The closest thing is a community written integration pasted below. A couple notes on this integrations:
for the best integration, it will require a separate z-wave or zigbee tilt sensor for your garage door
Support in the new app might be limited. Full support is in Classic, which doesn’t have full functionality for new users migrating from Wink which can lead to confusion.
