August SmartLock (Non Z-Wave) + Connect

What’s the exact model? But, yes, you have to have the pro 3 model with Z wave to have it work smoothly with SmartThings.

Some people have tried some fairly wonky MacGyver type methods to get partial integration for earlier August models. The most reliable seems to be to use the free yonomi app and A Wemo switch to stand in as a proxy for the lock. So when smartthings turns on the switch, you could have yonomi lock the August. But it’s a very limited integration.

There are some people have tried to reverse engineer the connect for the earlier models, using a raspberry pi or a mini Mac as a server, but none of those methods seem to work very well and there’s a very real risk of killing the lock battery because of too frequent polling. The WeMo method is both simpler and more reliable.
