@steve.hoge thanks I'm new to Hubitat and Groovy (like yesterday new 
) but gave this a try based on your Python code (I love Python). This Driver so far will get the access token after you enter in your UAID and Secret Key, save, then press configure. This will also then populate the devicesList state variable after you refresh. Then you can plugin the deviceToken and deviceID in the preferences and save, and now use the refresh button to pull those state variables from the sensor. Note I'm using this with a motion sensor, so be sure to change the part to your device type if not using MotionSenor in the getMotionSensorDetails command and also the updateState logic to reflect your state variables.
I don't quite know how to setup polling or use the HTTP Callback API for YoLink I see mentioned on the API docs so that the state would update based on a motion event. Sorry if it is a little rough, still learning everything but wanted to share in case it helps anyone else get closer to something working.

I got it basically installed and talking to my Hub and it's listing my devices!
