Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:brickletdualbutton:[UID]")
val hwVersion = actions.brickletDualButtonGetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletDualButtonGetLEDState()
Return Map:
  • ledL – Type: short, Range: See constants, Default: 1
  • ledR – Type: short, Range: See constants, Default: 1

Returns the current state of the LEDs, as set by the thing configuration.

The following constants are available for this function:

For ledL:

  • val LED_STATE_AUTO_TOGGLE_ON = 0

  • val LED_STATE_AUTO_TOGGLE_OFF = 1

  • val LED_STATE_ON = 2

  • val LED_STATE_OFF = 3

For ledR:

  • val LED_STATE_AUTO_TOGGLE_ON = 0

  • val LED_STATE_AUTO_TOGGLE_OFF = 1

  • val LED_STATE_ON = 2

  • val LED_STATE_OFF = 3

brickletDualButtonGetButtonState()
Return Map:
  • buttonL – Type: short, Range: See constants
  • buttonR – Type: short, Range: See constants

Returns the current state for both buttons. Possible states are:

  • 0 = pressed

  • 1 = released

The following constants are available for this function:

For buttonL:

  • val BUTTON_STATE_PRESSED = 0

  • val BUTTON_STATE_RELEASED = 1

For buttonR:

  • val BUTTON_STATE_PRESSED = 0

  • val BUTTON_STATE_RELEASED = 1

Advanced Actions

  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char, Range: ['a' to 'h', 'z']
  • hardwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • firmwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • deviceIdentifier – Type: int, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here.
