If you want to try a smart device to upgrade your home, I would suggest a smart lock. The smart lock is practical and easy-to-use, as most versions connect to an app you can access on your phone.
Plus, you will never have to worry about losing your keys again. Smart locks are easy to install and will let you track each time your door is opened or closed. Here are some of the most popular smart locks:
– Nest x Yale Lock with Nest Connect
– August Smart Lock HomeKit Enabled
– Schlage BE479 V CEN 619 Sense Smart Deadbolt
– Courtney Conyers, The Boston 100
