To be real...kind of all of them. All the "smart" locks you see for sale are WILDLY insecure at the consumer level.
You are correct that almost all of them focus on the deadbolt, but look at something like this. I kind of hate this company, but they make components as well as entire lock systems.
I have no idea if they work with HA or not, just giving you a jumping off point to familiarize yourself with the options and terminology to have a deeper search.
