August announced an updated that adds Auto-Connect to its Smart Lock Pro and third generation Smart Locks for quicker connecting remotely. 

Currently, if you want to grant someone access to your home or check your lock's status remotely, you need to tap a remote connect button in the August app. Then, you'll have to wait for the lock to connect to your home's Wi-Fi network.
