Presence sensors

Paired sensors will appear on the Sensors page in the More tab. Presence sensors, Daylight sensors, and combined Presence/Daylight sensors will be shown. To minimise network data traffic, sensor motion detection or lux functions can be disabled in the individual sensor properties for sensors where the feature is unnecessary.

To configure a presence sensor, the Use Control Hierarchy option must first be enabled (see section on Network setup/Control options). Note that, if it has not been enabled already in the Network setup/Control options, you will automatically be prompted to enable Control hierarchy when trying to configure the first sensor in a network. There are different configuration options for each sensor:

•    Presence

•    Presence/Absence

•    Absence

•    Resume automation (group)

•    Resume automation

Presence can activate up to two mutually exclusive scenes when the sensor is triggered. Activates a scene when presence is detected and deactivates it after presence is no longer detected and the linger time has expired.

Presence/Absence activates up to two mutually exclusive scenes when the sensor is triggered, and up to two mutually exclusive scenes when motion stops and linger time ends. So this function activates a scene when presence is detected and changes to the absence scene after presence is no longer detected and the linger time has expired.

• Note: Presence and Absence scene(s) must contain the same luminaire(s).

Absence Removes manual control from selected scene(s) when presence is no longer detected and the linger time has expired (see below). e.g. The scene(s) are activated manually (e.g. by a switch) but automatically deactivated.

Local control is sensor profile specific, so will not always appear in the app. If available, it allows compatible sensors to directly control only the luminaire in which it is installed with a predefined “Mode/Scene” for Presences and Absence.

Linger time Is the delay between presence no longer being detected and the controlled scene(s) expiring.

Fade time Is the time it takes the scene(s) to dim to off (0%) or to the Absence scene once presence is no longer detected and the linger time has expired.

Absence timeout defines how long the Absence scene will remain active. By default, it is Disabled (i.e., The absence scene will not turn off).

Removes manual control Allows any previous manual control of a scene to be removed once presence is no longer detected and the linger time has also passed.

Sensor is activated by trigger is only visible in Presence/Absence mode and ensures the sensor will stay inactive until the Presence scene is triggered by another method and only remains active and detecting motion until the Absence timeout expires.

The two Resume automation options can be used to remove manual control from a specific group of luminaires or from all luminaires in your network.

A presence sensor will display a ‘walking person’ icon in the top right of the main sensor icon image when presence is detected.

Note: mains-switching PIR sensors can also be used with the CBU-ASD or CBU-TED to act as a Casambi-enabled sensor. The profile of the CBU device may first need to be changed to enable this (See Changing a device profile in the Appendix).

Up to 30 sensors (for Evolution networks), or 10 sensors (for Classic networks) can be configured to control the same luminaire.
