I’m trying to implement a constant lighting system for a bird refuge, where the day starts at 7:00 AM and ends at 8:00 PM. The goal is to have the floodlights dim in and out over a 20-minute period, similar to sunrise and sunset. After that, specific spectrum lights should turn on and off at certain times, and UVB lights should operate for a few hours during the day.
I initially planned to use a KNX clock for switching, but I’m struggling to find a solution for the dimming functionality within the KNX realm. The ideal setup would involve using the Siemens building control system’s weather station data, which provides external lux levels, to adjust the lighting accordingly.
I’m considering using the OpenHAB rule engine as the basis for this system. The challenge is to create a ballpark dim value based on the external lux without equipping the entire facility with photosensors. Has anyone successfully implemented a similar system or have advice on how to approach this?
