The ZEN16 currently doesn't have the functionality to separate inputs from outputs, the inputs are fixed to outputs and you can only disable them (so that the connected switch for example, doesn't trigger the relay) but there's no way to have individual devices in Hubitat created for inputs separate of the outputs. This functionality is only available on the ZEN17. The built-in driver should cover most if not all of the settings and all other advanced settings can be accessed through the basic parameter tool.
The current version of the ZEN16 is 500 series so it doesn't feature the parameter labels like the 700 series devices do. BUT some good news: we're redesigning the ZEN16 at the moment and the new version will feature the 700 series chip as well as similar functionality to the ZEN17 model (with inputs separated from outputs).
