The Wheel control is a control dial to control functions (for example volume) inside the IRControl System. For this you have to define an actions for both direction of rotation. But there exists devices types, that can be configured explicit.

Control Attribute

Bluesound System If you want to use the wheel control for volume control of a BlueSound device, you can set the Id of the Bluesound System at this place. For other use of this control this attrbute must be empty.
Bluesound Device With this attribute you can confgiure a Bluesound Device optionaly in addtion to the Bluesound System parameter. If you don’t set this parameter the volue control has imapact to all connected Bluesound System, otherwise only for the specified one.
Dimmer Device With attribute you can configure different devices with a fix range of values (0 – 100 %). Possible devices: Philips Hue Light, Philips Hue Group, openHab Thing (Item Dimmer), FRITZ!Box DECT 301

Design There are 2 design types for the wheel control at your disposal (grey and green)
Value from / Value to Here you can configure absolute values defined wheel (e.g. 0 until 100 or also -40 until 40). You have to register an Action with Trigger „state“ and a Trigger with „value“. This is only possible for devices for which we can determine the acutally value and do also set the it with an abolsue value. For tevices we control with a infrared singnal, this is not possible
ID Optional attribute. Is is used for some special configurations only.
