Lighting Control Functionality

The lighting control solution shall provide the following functionalities:

Basic lighting control functionality: Basic lighting control functionality such as turning the luminaires on/off, dimming the light level, adjusting the colour temperature and setting colour for colour changing luminaires.

Grouping: Grouping is a method of organizing luminaires. This can make it easier to find the correct luminaires later (especially in a large network). One luminaire can only be part of one group.

Scene control: A scene can be recalled at any time from a user interface, or it can be programmed to start at a certain time. It shall be possible to have multiple scenes active at the same time. A scene can be a certain dimming level, or a combination of a dimming level and a colour, a combination of a dimming level and a colour temperature or a preset adjustment of the indirect/direct lighting ratio- depending on what kind of luminaire is being controlled. It shall be possible to create up to 255 scenes per network.

Animations/dynamic scene control: Dynamic scenes consist of lighting situations that change throughout the time they are active. Dynamic scenes shall include adjustable fade times, to fade into and out of different lighting scenes. Dynamic scenes shall have the possibility to be set to be one-off or to be on repeat.

Time based scenes: Consists of at least two “conditions” with different scenes or scene dimmed levels for each. Depending on when the time-based scene is activated, the relevant lighting scene condition for that time will be actioned.

Calendar events: The Calendar functionality shall allow scenes and animations to be turned on and turned off based on a certain time and date. The options are to either choose a certain weekday or several weekdays or a specific date. After this the exact time can be chosen or also according to local sunrise and sunset times. It shall also be possible to set the fade time for turning on and off luminaires/scenes with the timer functionality.

Daylight control: Daylight sensors shall function in the lighting control system and shall be allowed to choose if the sensor is affected or not by artificial lighting. The lighting control solution shall allow four daylight sensing approaches:

Basic: Luminaires in an active scene will switch ON or OFF based on two configurable Lux threshold levels. Sensors may or may not be affected by light from nearby luminaires.
Closed loop: The sensor actively adjusts the luminaires to try to reach and maintain that lux level via a feedback loop. Sensors are affected by light from the luminaires in the scene. In the closed loop mode it shall be possible to initialize control with initial dim levels that depend on the current sensor value.
Open loop: Luminaires will have their output level adjusted by comparing the sensor's lux reading against a response graph. Sensors should not be affected by any light from the luminaires in the network.
External: This is like the Open loop option, but it is based on a 0-100% dimming signal being sent from the sensor rather than a lux level.

Circadian control: The lighting control solution shall have the capability of controlling the colour temperature of tuneable white luminaires based on daytime. It shall allow automatic colour temperature management for regular scenes by using a response graph that spans the hours of day on horizontal axis and colour temperature on vertical axis. Users with Manager or Admin accounts shall have access to the circadian control curve from the App and to be able to modify the curve. It shall be possible to use Circadian control simultaneously with daylight control.

Sunset/sunrise control: The lighting control solution shall have a possibility to control lighting based on sunset/sunrise times, with configurable offsets, using the geographical location of the network.

Movement detection: Motion sensors shall function in the lighting control system. It shall be possible to configure presence, absence, linger time and fade time. It shall be possible to configure up to 30 sensors to control the same luminaire or control group. Each sensor can trigger up to 2 scenes.

Gallery function: The lighting control solution shall have a graphical interface where it should be possible to control lighting directly from a picture in the App with easy gestures. The functionality shall be flexible and permit the user to choose any kind of picture like a real photograph of the space, a floor plan or a render. Several pictures can be added and arranged. This function should not require any special software or drawing tools.

Switches: The lighting shall also be controllable from standard wall switches or momentary action switches. The switch shall be connected to a wireless control module. The settings for the switch shall be configured from the App and shall control one or multiple luminaries.

System Emergency Override: The lighting control solution shall include a feature to create an "emergency switch" from a latching wall switch. When the power to that device is ON, the assigned scene is activated and is only disabled when power to the device is switched OFF. It means that luminaires used in the Emergency scene cannot be controlled by any other method until the Emergency device is powered OFF.

Remote Access: The system must have a remote access functionality via the App or a Cloud Gateway, facilitating maintenance or troubleshooting.

Control Hierarchy: The lighting control solution shall allow a co-operation with manual lighting control (app, switches and push buttons) and automated controls (presence sensors and timers) to be able to create overrides and lighting control priorities. Each control action shall have a specific priority and if multiple controls are simultaneously controlling a luminaire it will adhere to the highest priority. When the highest priority control is removed the luminaires will fade into the next highest priority. If hierarchy is empty the luminaire will turn OFF.

Integration with DALI networks: The lighting control solution shall facilitate seamless integration between wired DALI networks and wireless networks. A wireless device, connected to the same powered DALI bus as the DALI controller, acts as a gateway, allowing control of all wireless luminaires through the DALI controller software. Alternatively, another wireless device can be utilized, enabling all DALI luminaires connected to it to appear as wireless devices in the lighting controls App. This option offers individual programming and control capabilities for up to 64 DALI luminaires through the user-friendly App.

Simple replacement of nodes: The wireless lighting system shall provide the possibility to easily replace an existing node with a new one without the need for a specialist. All settings and functionality from the old node will be copied to the new node using the App and no completely new pairing process shall be required.

Network history: The control system shall support a history which allows two recovery options: BACKUPS and SNAPSHOTS. Both options are stored copies of the network program. Snapshots are saved automatically, whereas backups are created and stored manually. A total of 50 snapshots will be stored automatically. When more are stored, the oldest will be removed to allow space for the newest.

Network storage indicator: A system device storage percentage shall be provided by App where there must be an indication of the network storage and the space consumed to present the available storage area left.

Nearby Devices: The system shall enable scanning and identification of nearby devices. Users shall have the ability to sort and filter these devices within the app, allowing for organized and efficient display.
