User objects are used to send commands to the server. There are few different user objects:

Commands can be dealt with from Java or JavaScript in the events environment.

Every user object has a name and a parameter, that are sent to the server, and a repeat mode. If this mode is enabled, the behaviour will change:

  • No repeat mode - the command is sent on the mouse up or touch up events

  • Repeat mode enabled - three types of commands are sent:
    • down: on mouse down or touch down events
    • repeat: if the button is still pressed, a repeat command is sent every second
    • up: on mouse up or touch up events, for a short press (less than a second, so no repeat commands have been sent yet)
    • stop: on mouse up or touch up events, for a long press (more than a second, so at least a repeat command has been sent)

A UserList object has a list of items, each behaving like a user object.


While programming keep in mind that due to connection errors or user inputs (e.g. changing page) communication could be interrupted, so in the case of a user object with repeat mode enabled, the final command (up or stop) could be lost

  • on/off: no repeat, switches the dimmer on and off
  • +: repeat mode, while pressed will increase the dimmer's value
  • -: repeat mode, while pressed will decrease the dimmer's value
