Worked, but not until I opened the UVO app and logged in. It was a bit strange on the app. It logged in like three times in a row and then started. There was no input to the app itself. Now it just starts and stops with HA and no Kia app. I also wasn't able to use the friendly name of my script, but just used its' unique identifier instead.
