Block colour selector RGBW

This control element sets the colour of a coloured light, for instance an LED strip. The colour is picked in the colour wheel; brightness, white share and five favourite colours for quick recall complete it. Switching times, the behaviour on presence and absence and a presence simulation round off the operation.

Operation

Colour: the circle in the centre shows the colour currently set.
Outer ring: if there is a white channel, the grey ring shows the white share – the lighter the ring, the more white. Without a white channel the colour fills the whole circle.

A tap on the element opens the dialog. As a circle (basic screen) the element shows the same, only without a caption.

The dialog

Clock, presence, settings – the three symbols in the title bar, see below.
Colour wheel: tap it or drag your finger across it; the colour under the finger is applied and sent to the light.
Preview: shows the selected colour including its brightness.
White (sun): sets the white share, top 100 %, bottom 0 %. The slider only appears if the light has a white channel.
Brightness of the colour: the full colour sits in the centre. Downwards it becomes lighter up to white, upwards darker down to black.
Favourite colours: a tap recalls the colour and closes the dialog. To assign a button, first set the desired colour, then hold the button for 2 seconds – it gets a yellow frame, the colour including the white share is stored. Preset ex works are off (black), red, green, blue and white. A button can only be reassigned if the element is linked to a function block. Without a block the factory colours remain.

Switching times and presence

Behind the clock are switching times that set a colour at a certain time – on request only when it is bright or dark. Everything else about switching times is described under Presence.

Behind the house you define which colour is set when the presence changes. A tap on a symbol selects whether anything is switched at all in this state; a tap on the colour field next to it opens the colour selection. Black switches the light off. Ex works only Present is active, with white.

Settings

The gear wheel opens the settings. Save applies them.

Brightness

Defines from when it counts as bright or dark: Threshold bright and Threshold dark, each in lux. The brackets show the brightness currently measured. The thresholds apply to switching times with “If bright” or “If dark” as well as to Start only when dark of the presence simulation and only take effect if a brightness value is available. Default for new elements: Threshold bright 1000 lx, Threshold dark 100 lx.

Presence simulation

Switches the light on in random colours and off again so the house looks lived in. The three symbols select in which state it runs – usually Vacation. When the simulation ends, the light is switched off.

Start / End: period in which the simulation switches.
Count from / to: how often the light is switched on in this period. The number is chosen at random within this range and spread randomly over the period.
Duration from / to: how long the light stays on each time, in minutes, also at random within this range.
Start only when dark: the simulation only switches the light on if the brightness is not above Threshold dark; if it is still too bright, this switching on is skipped.

Setup

This section is meant for the installer of the system.

Two variants

The control element comes in two variants:

Operation presence – is linked to the function block Block colour selector RGBW: first create the function block including its variables, then right-click the control element and select the function block. The variables sit at the function block. Only this variant offers switching times, presence and settings. See also Presence.
Standalone – without a function block, the variables are linked directly at the control element. The dialog then carries the text of the element as its heading and has no symbols in the title bar.

The colour is output either via the three channels Red, Green and Blue or as one combined value RGBW; both at the same time is also possible. The single channels may be of type EIS 6 (relative value 0-100 %) or EIS 14 (counter value 1 byte, 0 to 255), the combined value of type EIS 18 (RGB 3 byte) or EIS 19 (RGB 6 byte, with white). The tile shows the values of these variables.

With the function block, switching times with bright/dark only work if its input Brightness is linked; otherwise the switching time does not offer this choice.

Parameters

Display
Scene selection	Defines whether the element can be selected in the control element Block Scene group. Default: on.
View	Block (tile) or Basic screen (circle, e.g. for a floor plan). The third choice List(deprecated) comes from older projects and should no longer be used.
Text	Caption of the tile. Its size scales with the element, a line break is inserted with \n, at most two lines.

Variable links

With the variant presence all variables sit at the function block. With the variant standalone the following are linked at the control element:

Red / Green / Blue	The three colour channels. They are sent as soon as a colour is picked in the dialog, and their values determine the colour shown. Optional if RGBW is linked instead. Not linked: this channel is not sent.
White	Optional. White channel, 0 to 100 % or 0 to 255. Not linked: the white slider in the dialog and the grey ring on the tile are omitted.
RGBW	Optional. The colour as one combined value (EIS 18 or EIS 19, with EIS 19 including white). Not linked: only the single channels are sent.
