Hi Thomas,
For information, it is easy to implement constant lighting using the schneider electric KNX/Dali gateway coupled with Argus present + lux sensor.
In your knx project, you will create group address for "auto control" with Dali Gateway and KNX presence sensor dedicated objects. According to the setpoint, your controller (KNX/Dali gateway) will send Dali command to luminaries to dim up or down until the lux setpoint value +/- hysterisis is reached. This solution can be applied with or without LM or HL (standard KNX button 2 gangs or push button pro or Multitouch pro can be used)
For pure KNX or any other prococol (modbus, enOcean, etc...), if you don't have the dedicated device for lighting regulation, you need to write or modified PID script, use Logic Machine or SpaceLynk or HomeLYnk as gateways and controllers to deal with constant lighting.
Best regards,
Chouaibou.
