Detailed Description

This is a fixed size datapoint type with the length of 1 byte, though only one bit is used by the actual implementation.

It is a base class for the following datapoint types:

  • QKnxAck - Acknowledge command (trigger) for alarms, for example. Possible values are Acknowledge and No action (dummy).
  • QKnxAlarm - Possible values are Alarm and NoAlarm.
  • QKnxBinaryValue - Possible values are Low and High.
  • QKnxBool - Possible values are False and True.
  • QKnxDimSendStyle - Dim send style. Possible values are Start/Stop or Cyclically.
  • QKnxEnable - Possible values are Disable and Enable.
  • QKnxHeatCool - Possible values are Cooling and Heating.
  • QKnxInputSource - Possible values are Fixed and Calculated.
  • QKnxInvert - Possible values are Not inverted and Inverted.
  • QKnxLogicalFunction - Possible values are logical function OR and logical function AND.
  • QKnxOccupancy - Possible values are Not occupied and Occupied.
  • QKnxOpenClose - Possible values are Open and Close.
  • QKnxRamp - Possible values are NoRamp and Ramp.
  • QKnxReset - Possible values are No action (dummy) and Reset command (trigger).
  • QKnxSceneAB - Possible values are Scene A and Scene B.
  • QKnxShutterBlindsMode - Shutter or blinds mode. Possible values are Only move Up/Down mode (shutter) and Move up down + StepStop mode (blind).
  • QKnxStart - Possible values are Stop and Start.
  • QKnxState - Possible values are Inactive and Active.
  • QKnxStep - Possible values are Decrease and Increase.
  • QKnxSwitch - Possible values are Off and On.
  • QKnxTrigger - Possible values are Trigger and Trigger (also).
  • QKnxUpDown - Possible values are Up and Down.
  • QKnxWindowDoor - Window or door. Possible values are Closed and Open.

The possible values for this datapoint type are true and false.
