Configure light behavior

There are three components to light behavior: behavior settings, high end trim, and daylight sensing settings. Daylight sensor calibration should only be done after the light behaviors and scenes have been deployed to the group, so that will be covered in a following section.

High end trim

High end trim is an optional setting that limits the maximum light/power output of a group below its normal maximum. If a high end trim is desired, it is advisable to set it before the light behavior and scene levels are configured because it will proportionally reduce these levels, potentially making them too dim.

  1. Navigate to the appropriate group, then tap Controls.

    controls1

  2. Under the Light behavior section, tap High end trim.

    config grp bhr 1

  3. Move the slider to achieve the desired reduction in maximum light level or power reduction. The reduction in light level and power is linear to the eye but is exponential in its actual reduction (Refer to Dim curve for more details).

  4. Tap the < chevron to navigate back to the group Controls screen.

Behavior settings

Behavior settings enable different group responses to occupancy, vacancy, and daylight sensing. Light behavior V2 groups allow up to six different states to be stored by devices in the group, while non-Light behavior V2 groups only store a single state. In Light behavior V2 groups, each created state can be independently named and configured. These states can then be recalled by the mobile app, enabling users to switch between lighting behavior states for different operational needs without requiring manual group re-configuration.

  1. Navigate to the appropriate group, then tap Controls.

    controls1

  2. Under the Light behavior section, tap Behavior settings.

  3. For non-Light behavior V2 groups, in the Behavior settings screen, configure the light behavior state parameters according to the requirements and tap Save. To know more about the light behavior state parameters, refer Light behavior state parameters.

  4. For Light behavior V2 groups, in the Behavior settings screen, scroll down and tap Add state. In the Add a state screen, enter a state name in the State name field, configure the light behavior state parameters according to the requirements and tap Save. To know more about the light behavior state parameters, refer Light behavior state parameters.

    For Light behavior V2 groups, up to six light states can be created and saved.

    In Light behavior V2 groups, when Minimum dim level is set to Off, the setting works independently of Daylight sensing, provided that Daylight sensor zone calibration has been completed. This behavior applies even when Daylight sensing is disabled in the active state.

Available UI settings

The available UI settings vary depending on whether a supported outdoor parking sensor is present in the group.

No supported outdoor parking sensor present

When no supported outdoor parking sensor is available in the group:

  • Minimum dim level is displayed.

  • Daylight sensor zone calibration is displayed.

  • The Indoor/outdoor selection is not displayed.

  1. Adjust the Sensitivity to turn lights On slider:

    • Move the slider towards Low to require darker conditions before the lights switch on.

    • Move the slider towards High to switch the lights on sooner as daylight levels decrease.

    • Medium is the default setting.

  2. Adjust the Threshold to turn lights Off slider:

    • Move the slider towards Low to switch the lights off sooner.

    • Move the slider towards High to require brighter daylight before the lights switch off.

    • Medium is the default setting.

  3. Tap Save.

    Result: Outdoor daylight override uses factory-calibrated daylight thresholds and does not require daylight sensor zone calibration. Supported outdoor parking sensors automatically control light output based on ambient daylight levels.

Daylight sensor zone calibration

Daylight sensor zone calibration calibrates zones for Daylight sensing and should only be performed after the group settings have been deployed.

The Daylight sensor zone calibration section is available when:

  • No supported parking sensor is present in the group.

  • Indoor / covered parking is selected.

The Daylight sensor zone calibration section is not available when Outdoor / uncovered parking is selected because supported parking sensors use factory-calibrated daylight thresholds for daylight override.

Prerequisites

To ensure accurate and effective daylight sensing operation:

  • Perform calibration when ambient light entering the space through windows, skylights, or other openings is minimized. Calibration should preferably be completed at night or when daylight can be blocked using blackout shades, window coverings, or similar methods.

  • Calibration of a zone takes approximately six minutes.

  • Multiple zones can be calibrated simultaneously if the lights in one zone do not affect the light levels in another zone. If zones influence each other, perform calibration one zone at a time.

  • A lux meter is required if the installation must be calibrated to a specific lux level.

Configure daylight sensor zone calibration

  1. Navigate to the appropriate Group, then tap Controls.

    controls1

  2. Under Light behaviour, tap Daylight sensing settings.

  3. In the Daylight sensor zone calibration section, tap the required zone.

  4. Review the Preparing for calibration information, then tap Got it.

  5. Adjust the default light level to the required setpoint.

    default light level

  6. Tap Calibrate. Wait for the calibration process to complete. Calibration takes approximately six minutes.

    Do not control the lights while calibration is in progress. If the hold time is set to five minutes, ensure occupancy is detected during calibration to prevent the lights from transitioning to the background level.

  7. Tap Continue.

  8. Repeat the calibration procedure for any additional zones that require daylight sensing.

Sensor info - occupancy sensing

Lights with built-in sensors and standalone mains powered sensors can have their occupancy detection individually enabled or disabled once they are added to a group. If a sensor in a room is too close to a door or HVAC vent for example, its occupancy sensing can be disabled to avoid unnecessary motion triggering from passing motion or HVAC systems.

Occupancy sensing settings are not supported by ZGP battery-powered sensors, as they cannot have their occupancy sensing disabled if added to a group.

All built-in or mains powered sensors in a group must have the minimum firmware level to support this function. If the minimum firmware version is not met by all sensors in a group, the occupancy sensing per sensor option will be disabled. The firmware of the sensors can be updated by adding gateways and running a project update (Refer to Project Updates for more details), or by updating the sensor(s) using the BLE OTA update function.

  1. Navigate to the appropriate group. The Lights screen is shown by default.

    lights tab

  2. To adjust occupancy sensing settings for lights with built-in sensors from the Lights screen, tap the Info icon beside the light to load the Light info screen. Scroll down to the Occupancy sensing section, then tap to toggle the light’s occupancy sensing on or off accordingly.

    Tip: Tap the light icons to blink each light if you are not sure which light you need to adjust.

  3. To adjust occupancy sensing settings for mains powered sensors, or as an alternative way to adjust occupancy settings for built-in sensors, tap Controls, then tap Sensors in the Group controls section. Sensors will be listed by the types that are installed in the group under three sections: Battery powered (occupancy sensing settings not supported), Mains powered, and Integrated sensor luminaires.

    • For mains powered sensors, tap the chevron beside the desired sensor to load the Sensor info screen. Scroll down to the Occupancy sensing section, then tap to toggle the sensor’s occupancy sensing on or off accordingly.

      Tip:Tap the sensor icons to blink each sensor’s LED indicator if you are not sure which sensor you need to adjust.

    • For built-in sensors, tap the Info icon beside the desired sensor to load the Sensor info screen. Scroll down to the Occupancy sensing section, then tap to toggle the sensor’s occupancy sensing on or off accordingly.

      Tip: Tap the light icons to blink each built-in sensor if you are not sure which sensor you need to adjust.

Sensor info - occupancy sensing sensitivity

Lights with built-in sensors and standalone mains powered sensors can have their occupancy detection sensitivity adjusted individually once they are added to a group. If a sensor is in an office where the occupant sits still for prolonged periods for example, it may be desirable to increase the sensitivity to reduce unnecessary timeouts. Occupancy sensing sensitivity settings are not supported by ZGP battery-powered sensors (they cannot have their occupancy sensing disabled if added to a group).

Only SC200 built-in sensors and mains powered sensors (MPS) support sensitivity adjustment. Older SNS210 IA built-in sensor models do not support this function. All sensors in a group must have the minimum firmware level to support this function. If the minimum firmware version is not met by all sensors in a group, the occupancy sensing sensitivity per sensor option will be disabled. The firmware of the sensors can be updated by adding gateways and running a project update (Refer to Project Updates for more details), or by updating the sensor(s) using the BLE OTA update function.

  1. Navigate to the appropriate group. The Lights screen is shown by default.

  3. To adjust occupancy sensing settings for mains powered sensors, or as an alternative way to adjust occupancy settings for SC200 built-in sensors, tap Controls, then tap Sensors in the Group controls section. Sensors will be listed by the types that are installed in the group under three sections: Battery powered (occupancy sensing settings not supported), Mains powered, and Integrated sensor luminaires.

    • For mains powered sensors, tap the chevron beside the desired sensor to load the Sensor info screen. Scroll down to the Occupancy sensing section, then tap the Sensitivity option and choose between High, Medium (default) and Low.

      Tip: Tap the sensor icons to blink each sensor’s LED indicator if you are not sure which sensor you need to adjust.

    • For built-in sensors, tap the Info icon beside the desired sensor to load the Sensor info screen. Scroll down to the Occupancy sensing section, then tap the Sensitivity option and choose between High, Medium (default) or Low.

      Tip: Tap the light icons to blink each built-in sensor if you are not sure which sensor you need to adjust.

      Changing the sensitivity of a battery-powered ZGP sensor is not possible via the mobile app. You can change the sensitivity of a ZGP sensor by rotating the sensitivity knob that can be found at the back of the sensor.

Sensor info - daylight sensing

Lights with built-in sensors and standalone mains powered sensors can have their daylight sensing detection for individually enabled or disabled once they are added to a zone in a group. Sensors not added to zones will have their daylight sensing option fixed as disabled. Daylight sensing settings are not supported by ZGP battery-powered multi-sensors. Do not use ZGP multi-sensors in the same zone with built-in and/or mains powered sensors.

  • When daylight sensing is enabled in a sensor, it will regulate the light level based on its own light level detection, independently from other sensors in the zone.

  • When daylight sensing is disabled in a sensor, the sensor will follow the Zone master for daylight sensing, which is another sensor in the same zone that is selected to be the daylight reference for:

    • All other built-in or mains powered sensors in the zone with their daylight sensing option disabled

    • Any lights in the zone without a built-in sensor

All built-in or mains powered sensors in a group must have the minimum firmware level to support this function. If the minimum firmware version is not met by all sensors in a group, the daylight sensing per sensor option will be disabled. The firmware of the sensors can be updated by adding gateways and running a project update (Refer to Project Updates for more details), or by updating the sensor(s) using the BLE OTA update function.

  1. Navigate to the appropriate group. The Lights screen is shown by default.

  2. Tap the appropriate Zone where you wish to configure daylight sensing settings.

  3. To adjust daylight sensing settings for lights with built-in sensors from the Zone screen, tap the Info icon beside the light to load the Light info screen. Scroll down to the Daylight sensing section, then tap to toggle the light’s daylight sensing on or off accordingly.

Sensor info - daylight sensing zone master

Lights with built-in sensors and standalone mains powered sensors can be chosen as a zone master once they are added to a zone in a group and their daylight sensing option is enabled. Zone master settings are not supported by ZGP battery-powered multi-sensors. Do not use ZGP multi-sensors in the same zone with built-in and/or mains powered sensors.

  • When daylight sensing is enabled in a sensor, it will regulate the light level based on its own light level detection, independently from other sensors in the zone.

  • When a sensor is additionally enabled as the Zone master for daylight sensing, that sensor becomes the daylight reference for:

    • All other built-in or mains powered sensors in the zone with their daylight sensing option disabled

    • Any lights in the zone without a built-in sensor

  • There can only be one zone master sensor per zone. Enabling a sensor as a zone master will automatically disable any other sensor that was previously set as the zone master.

  • When there are lights in the zone without a built-in sensor, a zone master must be enabled for these lights to respond to daylight sensing.

All built-in or mains powered sensors in a group must have the minimum firmware level to support this function. If the minimum firmware version is not met by all sensors in a group, the daylight sensing zone master per sensor option will be disabled. The firmware of sensors can be updated by adding gateways and running a project update (Refer to Project Updates for more details), or by updating the sensor(s) using the BLE OTA update function.
