continues to offer the first-generation August Bluetooth Keyless Home Entry Smart Lock in Red for $164.93 with free shipping. (aSavings via Walmart charges the same.) That's tied with our mention from a week ago as the lowest price we've seen. (It's also the best deal we could find now by $4, although most merchants charge at least $200.) It's compatible with most standard deadbolts, and works with Bluetooth-enabled devices to sense your approach and unlock automatically. It includes three mounting plates and three lock adapters; four AA batteries are required and included.
