Block Roller shutter/Blinds

This control element moves a roller shutter or a venetian blind – fully up, fully down or to a certain height, with a venetian blind also the angle of the lamellas. On top of that there are switching times, the behaviour on presence and absence, an automatic shading based on the position of the sun, brightness and room temperature, and a presence simulation.

Operation

1. Top row: shows the current height; a tap opens the dialog. A sun on the left means the automatic shading is active right now.
2. Arrow up: a short tap moves fully up, holding for 2 seconds moves the lamella step by step.
3. Stop: stops the movement.
4. Arrow down: a short tap moves fully down, holding for 2 seconds moves the lamella step by step.

Depending on the setup, short and long may be swapped. As a circle (basic screen) the element shows height and lamella; a tap opens the dialog.

The dialog

1. Symbols of the title bar: clock, presence, shading (sun) and settings, see below.
2. Height: the left slider sets the height. A tap on the value opens the input.
3. Lamella: the right slider sets the angle of the lamellas – only for venetian blinds.
4. Travel buttons: the single arrow moves fully up or fully down, the double arrow moves the lamella step by step.
5. Favourite positions: a tap moves to the position. To assign a new one, first set height and lamella, then hold the button for 2 seconds. A button can only be reassigned if the element is linked to a function block. Without a block the factory positions remain.

Switching times and presence

Behind the clock are the switching times – for instance moving up at 7 am and closing at sunset. Behind the house it is set where to move when the presence changes, for example down when leaving the house and up again when coming home. Both are described in detail under Presence.

Automatic shading

The sun in the title bar opens the shading. It moves the blind by itself to a protective position when the sun shines onto the window – against glare or to keep the room from heating up. The dialog is longer than the screen and is moved by dragging.

1. When: the three symbols select in which presence states the shading works – in the example when present and absent, not during a vacation.
2. Shading position: where to move while shading (Active) and where to move when the shading ends (Inactive) – height and lamella each.
3. Sun position: range of sun height and sun angle (direction) in which the sun shines onto this window. The current position of the sun is shown in brackets – that makes it easy to find the range on a sunny day.
4. Brightness: with Active shading additionally only happens when it is bright enough – so the blind stays up on dull days. Shading starts above Active over and ends below Inactive under, but only once it stays darker for as long as set under Time to inactive. That way the blind does not go up with every cloud.
5. Temperature: with Active shading only happens when the room is warmer than Active over; below Inactive under the shading ends.
6. Inactive as soon as condition no longer fulfilled: whether the shading only ends when all conditions have gone, or as soon as one is no longer fulfilled.
7. Status: the last row shows which conditions are fulfilled right now – for instance a sun when the brightness is sufficient.

Save applies the settings.

Settings

• Brightness: Threshold bright and Threshold dark in lux – the thresholds for “If bright” and “If dark” in switching times and presence. The measured value is shown in brackets.
• Presence simulation: moves the blind up and down at random so that the house looks lived in. The three symbols set when it runs – usually during a vacation. Start / End is the period, Number of / to how often it moves, Position from / to the range of the random positions. At the end of the simulation the blind moves once to Off pos. (height and lamella).

Setup

This section is meant for the installer of the system.

Two variants

• Operation presence – is linked to the function block Block Roller shutter/Blinds (right mouse button on the control element). The variables sit at the function block. Only this variant offers switching times, presence, shading and settings, see Presence.
• Widgets Standalone – without function block, the variables are linked directly at the control element. The dialog then carries the text as its heading and has no symbols in the title bar. It only opens when an address Height percent is linked.

The variables for the lamella are optional – for a roller shutter they stay empty, then the lamella slider and display are hidden. Without an address Shorttime the double arrows are left out in the dialog.

Tip: If the transparency is set to 0 and a height is linked, a tap on the whole area opens the dialog.

Parameters

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:
