The first person to send me the message receives and then I will delete or edit this post. The code expires on 31.12.2020. I’m not 100% sure it’s not related to my account with them, but you can try.
Honestly, I don’t even know how it works. I assume you need to have a device registered (your phone) at a certain distance to be able to unlock it with a single touch. I returned my Level Lock because the usual size didn’t fit my door and I was hoping to move soon, to which I couldn’t assume the size of my next door. Make sure you measure VERY accurately! Remove the current jam to get a flat measurement. I strive for better software and hardware that uses U1ultra broadband technology, with dreams of my Apple Watch unlocking the door once it’s in a very short time and locking once it’s out of range.
In terms of sharing visitors’ access to Level Lock with visitors, this should become easier in iOS 14 with App Clips, which means your guests shouldn’t download the Level app.
