I'm glad you've taken the plunge on this exciting endeavor, @Jessica3814 . As far as I know, Schlage is the only brand Airbnb integration currently supports. Looking at Airbnb Smart Lock Guide: Easy Smart Lock Installation for Hosts has Yale and August as "coming soon". It appears they will be supported, but there's not really any indication of the timing.
At the time that I bought the locks we're using, the only ones on the market that worked with Apple Home Key were the Schlage Encode Plus and the Level Lock+. Using Home Key was a big driver for why I limited it to only those two. The Yale Assure 2 does support that now, too, so I'd not dismiss it now. I don't know if you use Apple phones or if Home Key matters to you, but it's a big deal to me.
Not knowing the timing of when the airbnb integration will work with Yale, I'd probably get the Schlage if I was buying it today. At some point in the not-too-distant future, that could change. I haven't looked closely enough at the Yale yet to say it would overtake my favorite spot.
The one thing I dislike about the Schlage Encode Plus is that it does not support programming keycards for access. It's certainly something that could be added with a software update, but I don't know that they intend to do that. I'd like for guests to have the option to use a keycard I could share with them in the same way I use my phone. Not a huge deal and I've so far just let them use the access codes.
Yeah, before the airbnb integration, I created access codes via the Apple Home app and just shared them in messages via airbnb. (Though I could write an app that would set up codes similar to what the airbnb integration does, but have not done that.)
