I installed a Yale Assure lock about a year ago that includes the August app. It integrates with Airbnb so that each guest automatically receives a unique entry code.
Unfortunately, it’s completely unreliable: after about 11 months I started getting reports from guests that their code had stopped working in the middle of their stay (sometime in the middle of the night!).
August Support can barely communicate in written English and is of no help.
Basically, it’s so unreliable that I’m back to using a lockbox and physical key.
The Yale hardware, I should say, is fine. But everything related to August is buggy and terrible.
Don’t do it.
