SmartThings to HomeKit bridge for door locks

My automation system of choice in my house is Apple Home, but I have devices that are not directly compatible, including a Schlage door lock. It’s connected (via Zigbee and SmartThings), but not accessible via HomeKit / Apple Home.

In the past, I have used Homebridge and a plugin to connect this up. This worked fine for a while, but for some reason it would periodically stop working and require some maintenance steps (for the record, I’m sure this was my fault, and not a Homebridge problem!). I ended up just turning off the Homebridge server, and just used SmartThings with some Apple Shortcuts for automation.

Recently, though, I decided to tackle this again, but this time with some custom single-purpose code. st-hk-bridge is the result - a small server, which will run in a Docker container, that bridges a SmartThings-compatible lock into HomeKit:

I’ve been running this for a couple of weeks, and after ironing out a few kinks, it’s been working well. It uses the SmartThings API, so if you’d like to use it yourself, you’ll need to sign up for the (free) API, and get your deviceId and an access token.

The majority of the code was written by Codex, which has truly seen massive improvement over the last few months!
