August Smart Lock Pro + Connect Wi-Fi Bridge $165 @ Amazon (February 3, 2020)

I absolutely love mine, and at that price, it’s a no-brainer to me. (I know they’re coming out with a wifi one soon, but I still like this one a lot.)

I feel like I vaguely read once that if you have two of these locks, you lose the ability to do something. Auto-unlock? Auto lock? I’m not sure. Anyone know?
