Smart Door Lock? But Which One? How Hard Could it Be?

Not really a huge secret, but we decided to install an Aqara Smart lock for our front door. So how hard was it to install this smart lock? As it turns out, installing the Aqara U100 wasn't too difficult as all. And, it set up easily with my HomeKit environment. Best of all, I can now unlock the door with my watch, at the office, or even sitting on the sofa.
