I have two August Locks in my home, the first one is the pro-version could not be happier with it.  The second one was not the pro version, and I thought I'd be okay not having the wifi connectivity with it, I was wrong.  I purchased this wifi bridge to get it all connected, and it is working great.  My only disappointment with any of the products is that the non pro version doesn't support Z-Wave or Zigbee.  I was hoping the wifi bridge would add this feature, but it didn't.  Still overall I highly recommend.
