Command

A Command represents an action you can perform on a Device.

An instance of a Command object encapsulates information about that Command. You cannot create a Command object; you can retrieve them from a Capability or from a Device:

preferences {
    section() {
        input "theswitch", "capability.switch"
    }
}
...

// Get a list of Commands supported by theswitch:
def switchCommands = theswitch.supportedCommands
log.debug "switchCommands: $switchCommands"

// Iterate through the supported capabilities, log all suported commands:
// commands property available via the Capability object
def caps = theswitch.capabilities
caps.commands.each {comm ->
    log.debug "-- Command name: ${comm.name}"
}

arguments

The list of argument types for the command.

Signature:
List<String> arguments
Returns:
List < String > - A list of the argument types for this command. One of “STRING”, “NUMBER”, “VECTOR3”, or “ENUM”.

Example:

preferences {
    section() {
        input "theSwitchLevel", "capability.switchLevel"
    }
}
...
def supportedCommands = theSwitchLevel.supportedCommands

// logs each command's arguments
supportedCommands.each {
    log.debug "arguments for swithLevel command ${it.name}: ${it.arguments}"
}
...

name

The name of the command.

Signature:
String name
Returns:
String - the name of this command.

Example:

preferences {
    section() {
        input "theswitch", "capability.switch"
    }
}
...
def supportedCommands = theswitch.supportedCommands

// logs each command name supported by theswitch
supportedCommands.each {
    log.debug "command name: ${it.name}"
}
...
