Summary

This release focuses on improving the daylight harvesting function and fixing problems.

Daylight-dependent light regulation was improved.
- In the previous firmware version (1.0.5), when DDR is enabled the light goes to approximately 500 lx in a typical office situation. With 1.1.11, when DDR is enabled the lights go to “On level Presence” times 500 lx (i.e. 80% x 500 lx results in 400 lx target level).
- In addition, calibration can be manually initiated and then the lights go to On level Presence times the maximum light output of the luminaire (given by the operating current).
The possibility of commissioning an Ubisys gateway to enable the upgrade of firmware of all devices in a group was added.
Extended support for switches was provided.

When occupancy sharing is disabled the sensors of a group still do not work standalone: all lights of the group still go to On-Presence level when occupancy is detected. Only granular dimming does not occur.

When daylight-based control is enabled, the following limitations apply:
- The calibration routine for daylight regulation takes longer (about 7 minutes) than with higher firmware versions. For luminaires, where the calibration fails due to too little light reflections from dark surfaces (e.g., a dark grey carpet) in the field of view of the daylight sensor, the luminaire goes to maximum light output. In contrast to higher firmware versions the light level is not capped at the On level Presence. If this results in luminaires with too high light output, we recommend disabling daylight regulation of these luminaires.
- In case daylight control is enabled, a double press of Switch ON action (with wireless switch) is needed for lights to go to On level Presence. The 1st button press brings the lights to Background light level; a subsequent 2nd button press will bring the lights to On level Presence as expected.
- Two occupancy triggers are needed for the lights to go to On level Presence. In case people enter a room the luminaire that triggers occupancy first goes to background light level only while the other luminaires go to On level Presence when they trigger presence too. Within some minutes the light of the first luminaire slowly increases to On level Presence.
