@Lee-And-Eli0. I also host three listings, all with Schlage Encode smart locks. I never want to integrate with Airbnb as I love the Schlage app. If you search these forums you will find many discussions about pros and cons. One apparent con I believe is that once the times are automatically sent (determined by Airbnb) they cant be changed. So if you have a guest turn up early or they overstayed, went out and are now locked out and you want to let them in remotely you cant. Maybe this will change.
I also know the Schlage app tells you when the lock is low battery, you can add up to 100 codes per lock and vary the frequency to cater for regular cleaners, trades etc as well as the temporary ones for guests. I just like to rely on only one app. And no, I didnt get paid to say this 😉
By the way, Redcliffe is a lovely part of the world.
