The following will explain the basic concepts of smart apps and device type handlers. There’s always a device type handler, but the system will assign one at the time of pairing if it can. It just might be a simple generic one and not give you all the advanced features of a device.
In this particular case, the advanced features include using the second switch.
I’m not sure what the current status is on this particular model, so hopefully someone who knows more will respond.
