Here you can find definitions of some of the main terms used in the Casambi app. It is for guidance only and is by no means comprehensive.
Absence
- The state of being away, or not present
Animation
- A sequence of scenes activated automatically in a predetermined order
Automation
- Control by anything that does not involve human interaction (i.e. By timers or sensors)
Circadian rhythm/profile
- The change of luminaire colour temperature (cool/warm white) over time to promote human wellbeing.
Closed loop
- The daylight control method to achieve constant light levels in an area.
Daylight control
- Automatic control of the artificial lighting based on levels of natural light measured by one or more sensors.
Daylight gain
- An estimate of the amount of available natural light in an area directly under a luminaire. Daylight gain can be used to ensure luminaires by a window in a room are kept at a dimmer level than luminaires further in the room so as to achieve the effect of having the same level of illumination throughout the room.
External
- A daylight sensor mode similar to Open loop, but for use if the sensor provides DALI dimming commands instead of lux levels.
Fade time/fade out
- The speed at which lights will dim, or an underlying command will take control.
Flick unpair
- The method of unpairing a device from a network by rapid power disconnection/reconnection.
Group
- A collection of luminaires in the same physical area (e.g. all luminaires in a row or in one room).
Hierarchy
- Software functionality that defines which type of commands take priority over others if multiple types of command are being actioned simultaneously.
Linger time
- The time from when a presence sensor stops detecting movement before it deactivates the Presence scene.
Manual control
- Control by physical interaction (e.g. Pushing a button or switch, or by selecting a control or scene icon within the app).
Manual control time out
- The period of time that manual control remains active (i.e. If a scene is selected from a push button, automation commands will not affect luminaires in that scene until the timeout expires).
Open loop
- Daylight control where the measuring sensor is not receiving any light from luminaires it is controlling (i.e. the sensor could be outdoors and luminaires indoors).
Override presence
- The method to raise the importance (priority) of a day or date timer in the control hierarchy so that it becomes more important than a presence command.
Presence
- The state of being in an area.
Remember last state
- Luminaires will automatically store their last dimmed level when toggled off (i.e. power is NOT switched off). When toggled back on they will return to the stored level. This function also overwrites the dimmed level of a scene if the scene was first selected and then dimmed before being toggled off.
Resume automation
- Disable manual control commands that may be active at a higher level in the control hierarchy to allow the automatic control to take over (e.g. from sensors or timers).
- If done in the Luminaires tab with a Group open, Resume automaton will apply to that group only. In other cases it will apply to all luminaires in the network.
Scene
- A lighting scenario usually comprised of multiple luminaires set to a desired configuration (e.g. brightness levels and colours).
Smart-Switching
- Options to provide simple lighting control depending on how a luminaires power switch is turned off and on.
Startup -> Last state
- After power is removed and restored, luminaires will start at the dimmed level they were at before losing power.
Timeout
- The period of time a command remains active for.
Toggle
- Switching a luminaire on/off via a Casambi enabled device (i.e. Device power remains on).
