If you didn’t load the Edge driver from the beta channel than your probably using the old Dth. You can no longer add the Rboy Dth Enhanced Zwave thermostat driver that worked with the CT 100 and 101. There was a link that you would go to called IDE where you were able to load custom apps and drivers that has limited functionality now. Everything is done through the Cli or command line. There are a lot of community members creating drivers and helping with the transition. The link below will allow you to access the CLI through a gui and provides a lot of information about devices and such. I would set this up so you can see your devices and whether they are using a DTH or Edge driver. It was created by Taustin and he is one of the members that you should definitely read his posts. He has a lot of excellent info
Also, another developer named Mariano_Colmenarejo he has written most of the Edge drivers and they really work well. Another member that you should read also has excellent information. Read the below .
Pay attention to posts by @JDRoberts he has a lot of very useful information and I figured out most of my Smartthings stuff from reading posts from him since I moved over to Smartthings 5 years ago.
Ask lots of questions, everyone is very nice here and will help you.
