I realize this thread is a bit old but my wife and I just purchased a ST hub for ourselves in Jan and I just started playing around with device types. That said, I put together a “Smart Start” device handler for SmartThings that works OK for the basics at least and thought I would share. I have a Viper Smart Start but others use the same back end. If anyone knows of a better version or a way to collect the current status of the vehicle I would love to hear about it.
