ML200 is a new entry-level digital keypad smart lock with Bluetooth communication for semi-outdoor scenarios. With the water-resistant design in all aspects, it reliably secures the front door in some rainy situations. It's super easy to install on the existing lever or knob of a single-hole door directly, and finish the lock's setup with just a few processes in minutes. The additional Bluetooth Gateway allows you to unlock the door lock remotely, check the log history and share the temporary or dynamic passcode via ZSmart App. More importantly, you can unlock the lock with voice commands when paired with a compatible Amazon Echo or Google Nest device. ML200 will be a better choice for the front door, garage entry and dramatically creates a more straightforward, smarter, and more convenient life.
