Since you’re starting out with this, start using the edge drivers, which is what’s going to exist in the near future.
Edge drivers are controllers that are used to manage the devices that are installed in the hub.
The driver has to be installed on your hub from a web channel where the drivers are stored.
There are several channels, there is the official smartthings and many more. Each user or developer can create and share their channel with other users.
To enroll your hub in an edge driver channel you have to enter the invitation link to the channel and accept use it and press enroll for access to drivers.
Once hub enrolled you will see all the drivers available in the channel.
Install only the drivers you are going to use on your hub.
Once the driver is installed on your hub, you can add the device from the app with the option to search for nearby devices.
