916 SmartCode Touchscreen Deadbolt

Works perfectly with ADT Security Home Control App & Command Center Center Console. The key alike feature is also a bonus. Easy to set new codes for guests after having the Master Code. Random Digit feature "pressing 2 random numbers prior to entering code" gives extra level of security.

Buy this model if you want to connect to an existing home automation controller with Zigbee. Get the Halo WiFi model if you just want to use an app on your phone and Alexa. I see some reviews that say you can't control the 916 lock with Alexa. This is simply not correct. But you do need a Zigbee hub. A few of the Amazon Echo/Alexa speakers come with one, but most do not. There are two big advantages to the 916 over the Halo: 1. Zigbee takes less power than WiFi, so the 916 will require fewer battery changes. 2. The 916 does not require its own app. Having a different app for every smart device brand you own is a pain. I have my 916 controlled by Home Assistant, and Alexa can control the lock and report on its status. You should be able to do the same with Samsung Smart Things or Hubitat hubs.
