I managed to get things mostly working, however it looks like there are some issues with the new smartthings app. I created a parent device and a couple temperature and humidity sensors. The parent device shows "Connected" but the temp/humidity sensors continuously show "Checking Status". Each device's history shows updated values and if I look in the Smartthings Classic app everything appears as expected, however I also can't create any new automations with these devices in the new app.
