How do I turn outdoor DALI lights on from 6:00 AM to 8:00 AM only if it is still dark

Problem
The customer wants outdoor lights to come on between 6:00 AM and 8:00 AM, but only when it is dark outside. A normal schedule cannot do this properly because sunrise changes through the year.

Solution
Use a Profile Schedule with the lux sensor in Twilight mode Nighttime recall max.

• At 6:00 AM, activate the profile with Twilight mode enabled

• At 8:00 AM, return to normal operation

Set the lux sensor thresholds so:

• lights turn on when lux drops below the Twilight on threshold

• lights turn off when lux rises above the Twilight off threshold

Example:

• On threshold: 300 lux

• Off threshold: 800 lux

If the sensor is only being used for this one function on that group, an alternative is to use Scene Validity:

• create an enable scene

• create a disable scene

• make the sensor valid only in the enable scene

• schedule the enable scene at 6:00 AM

• schedule the disable scene at 8:00 AM

Important
Make sure the lux sensor is not affected by the lights it is controlling, or the lights may cycle on and off.
