Introduction

wallcontrol10 is module for working with WallControll 10 command line interface over LAN-TCP. Decode responses from Wall Control 10 into JS values.

Main features

• connect over LAN-TCP
• execute native WallControl 10 commands
• decode responses into JS values
• command queue and time management
• events driven
• different schemas for connect-disconnect cycle

Usage

const WC10 = require('wallcontrol10');
//send-receive data using TCP socket
const dev = new WC10({host: '192.168.4.111'});
dev.emitter.on('responseFromDevice', data => console.log(data));
dev.process('wcmd -layouts'); //ask for layouts for default wall
dev.process('wcmd -layout="layout 1"'); //apply 'layout 1' for default wall

WC10cli Object

The primary exported object is WC10cli. It uses RAW object from raw-device as its prototype.

Constructor new WC10cli(AddressObject, OptionsObject)

• AddressObject <Object> - required.
  • name <string> - default 'WC10'
  • id <string> - default 'blueprint'
  • host <string> - required. Use valid IP address
  • port <number> - default 23
• OptionsObject <Object> - optional, default is {encoding: 'ASCII', duration: 1400, disconnect: true, splitter: {timeout: 1200}}
  • encoding <string> - default 'ASCII'
  • duration <number> - default 1400 ms. Inter-command period [ms]. A time for device to process command and to prepare and send a response.
  • disconnect <boolean|number> - default true. Connecion cycle scheme. Use true, false or timeout[ms]. True means close connection when command queue is empty, false means do not close connection, number means close connection after some ms. of connection inactivity.
  • splitter <Object> Used to select one among three supported transform streams which merge incoming data chunks and split it into valid messages. Only single property from delimiter, regex, timeout can be used. Default is {timeout: 1200}
    • delimiter <string> - use @serialport/parser-delimiter with string delimiter
    • regex <Regex> - use @serialport/parser-regex with regex
    • timeout <number> - use @serialport/parser-inter-byte-timeout with timeout. Response is completed if inter-byte time is longer then timeout. Please consider that timeout must be shorter than duration (inter-command period) and disconnect time (if disconnect use timeout scheme)

Method process(...commands)

Encode and send commands to controler. Commands will be queued and executed FIFO. You can use multiple commands in single call. Commands must be native WallControl 10 CLI commands as described in WallControl 10 Help/Tools/Command Line Interface or WallControl 10 User Guide. The most commonly used commands are:

• wcmd [-wall=wall_name] -layouts - Get layout names for given wall
• wcmd [-wall=wall_name] -layout=layout_name - Apply layout for wall
• wcmd [-wall=wall_name] -layout - Get current layout name for given wall
• wcmd -inputs - Get list of sources
• wcmd [-wall=wall_name] -openwindows - Get list of opened windows with their properties
• wcmd -wallstate - Get list of defined walls with their properties

Internal commands

There are some internal commands which start with #. They are not sent to controller, but are processed by WC10cli object itself.

• #pause duration - Append additional pause between neighboring commands as number of miliseconds.

Event: responseFromDevice

Emited when response from controller is properly decoded.

• response <Object>
  • dev <string> - controler name
  • id <string> - wall name
  • raw <string> - not decoded response
  • status <string> - response status. If command is executed OK, returned status is 'Success'
  • value <string|[string]|Object> - decoded response value. Returned type depends on request id (req).
  • req <string> - request id, used to identify response value. Currently following request are implemented:
    • req:'layouts' (available layouts), response for wcmd -layouts command
    • req:'layout' (current layout), response for wcmd -layout
    • req:'inputs' (available inputs), response for wcmd -inputs
    • req:'providers' (installed source providers), response for wcmd -providers
    • req:'windows' (opened windows), response for wcmd -openwindows
    • req:'walls' (available walls), response for wcmd -wallstate
    • req:'favourities' (available favourities), response for wcmd -favourities

Event: commandForDevice

Emited when command is properly encoded and sent to controler. Of course only encoded property is sent to controler itself.

• command <Object>
  • name <string> - device name
  • command <string> - a command itself, not parsed or encoded
  • encodedstr <string> - command encoded as string
  • encoded <Buffer> - command encoded as Buffer
  • duration <number> - time [ms] for device to process the command.

Event: connectionData

A data which comes directly from controler port "as is". Not decoded, merged or chopped by splitter

• data <Buffer>

Event: connectionStatus

Emited when device connection status changes.

• statusObj <Object>
  • dev <string> - device name
  • address <string> - device address as string
  • status <string> - connection status
  • more <string|Object> - additional status information
