# Switch on a type A socket with house code 17 and receiver code 1.
# House code 17 is 10001 in binary (least-significant bit first)
# and means that the DIP switches 1 and 5 are on and 2-4 are off.
# Receiver code 1 is 10000 in binary (least-significant bit first)
# and means that the DIP switch A is on and B-E are off.

Command Structure

The common options of the call and dispatch commands are documented here. The specific command structure is shown below.

tinkerforge call remote-switch-bricklet [<option>..] <uid> <function> [<argument>..]
Parameters:
  • <uid> – Type: String
  • <function> – Type: String

The call command is used to call a function of the Remote Switch Bricklet. It can take several options:

  • --help shows help for the specific call command and exits
  • --list-functions shows a list of known functions of the Remote Switch Bricklet and exits
tinkerforge dispatch remote-switch-bricklet [<option>..] <uid> <callback>
Parameters:
  • <uid> – Type: String
  • <callback> – Type: String

The dispatch command is used to dispatch a callback of the Remote Switch Bricklet. It can take several options:

  • --help shows help for the specific dispatch command and exits
  • --list-callbacks shows a list of known callbacks of the Remote Switch Bricklet and exits
tinkerforge call remote-switch-bricklet <uid> <function> [<option>..] [<argument>..]
Parameters:
  • <uid> – Type: String
  • <function> – Type: String

The <function> to be called can take different options depending of its kind. All functions can take the following options:

  • --help shows help for the specific function and exits

Getter functions can take the following options:

  • --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Setter functions can take the following options:

  • --expect-response requests response and waits for it

The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

tinkerforge dispatch remote-switch-bricklet <uid> <callback> [<option>..]
Parameters:
  • <uid> – Type: String
  • <callback> – Type: String

The <callback> to be dispatched can take several options:

  • --help shows help for the specific callback and exits
  • --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Basic Functions

tinkerforge call remote-switch-bricklet <uid> switch-socket <house-code> <receiver-code> <switch-to>
Parameters:
  • <house-code> – Type: Int, Range: [0 to 31]
  • <receiver-code> – Type: Int, Range: [0 to 31]
  • <switch-to> – Type: Int, Range: See symbols
Output:
  • no output

This function is deprecated, use switch-socket-a instead.

The following symbols are available for this function:

For <switch-to>:

  • switch-to-off = 0
  • switch-to-on = 1
tinkerforge call remote-switch-bricklet <uid> get-switching-state
Output:
  • state – Type: Int, Range: See symbols

Returns the current switching state. If the current state is busy, the Bricklet is currently sending a code to switch a socket. It will not accept any requests to switch sockets until the state changes to ready.

How long the switching takes is dependent on the number of repeats, see set-repeats.

The following symbols are available for this function:

For state:

  • switching-state-ready = 0
  • switching-state-busy = 1
tinkerforge call remote-switch-bricklet <uid> switch-socket-a <house-code> <receiver-code> <switch-to>
Parameters:
  • <house-code> – Type: Int, Range: [0 to 31]
  • <receiver-code> – Type: Int, Range: [0 to 31]
  • <switch-to> – Type: Int, Range: See symbols
Output:
  • no output

To switch a type A socket you have to give the house code, receiver code and the state (on or off) you want to switch to.

A detailed description on how you can figure out the house and receiver code can be found here.

The following symbols are available for this function:

For <switch-to>:

  • switch-to-off = 0
  • switch-to-on = 1

New in version 2.0.1 (Plugin).

tinkerforge call remote-switch-bricklet <uid> switch-socket-b <address> <unit> <switch-to>
Parameters:
  • <address> – Type: Int, Range: [0 to 226 - 1]
  • <unit> – Type: Int, Range: [0 to 15, 255]
  • <switch-to> – Type: Int, Range: See symbols
Output:
  • no output

To switch a type B socket you have to give the address, unit and the state (on or off) you want to switch to.

To switch all devices with the same address use 255 for the unit.

A detailed description on how you can teach a socket the address and unit can be found here.

The following symbols are available for this function:

For <switch-to>:

  • switch-to-off = 0

Advanced Functions

tinkerforge call remote-switch-bricklet <uid> set-repeats <repeats>
Parameters:
  • <repeats> – Type: Int, Range: [0 to 255], Default: 5
Output:
  • no output

Sets the number of times the code is sent when one of the switch socket functions is called. The repeats basically correspond to the amount of time that a button of the remote is pressed.

Some dimmers are controlled by the length of a button pressed, this can be simulated by increasing the repeats.

tinkerforge call remote-switch-bricklet <uid> get-repeats
Output:
  • repeats – Type: Int, Range: [0 to 255], Default: 5

Returns the number of repeats as set by set-repeats.

tinkerforge call remote-switch-bricklet <uid> get-identity
Output:
  • uid – Type: String, Length: up to 8
  • connected-uid – Type: String, Length: up to 8
  • position – Type: Char, Range: [a to h, z]
  • hardware-version – Type: Int Array, Length: 3
    • 0: major – Type: Int, Range: [0 to 255]
    • 1: minor – Type: Int, Range: [0 to 255]
    • 2: revision – Type: Int, Range: [0 to 255]
  • firmware-version – Type: Int Array, Length: 3
    • 0: major – Type: Int, Range: [0 to 255]
    • 1: minor – Type: Int, Range: [0 to 255]
    • 2: revision – Type: Int, Range: [0 to 255]
  • device-identifier – 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

Callbacks

Callbacks can be used to receive time critical or recurring data from the device:

tinkerforge dispatch remote-switch-bricklet <uid> example

The available callbacks are described below.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

tinkerforge dispatch remote-switch-bricklet <uid> switching-done
Output:
  • no output

This callback is triggered whenever the switching state changes from busy to ready, see get-switching-state.
