My rollershutters are closing/opening based on astro binding sunrise & sunset. As this was not precise enough I bought a light sensor which gives quite nice lux values.
Based on this lux value I can close the rollershutters now (when lux <= 50 && rollershutters == OPEN).
When thinking about enhancing the “opening the shades” with that lux value something came to my mind:
- When the automatic outdoor lights are getting activated due to movement, the lux value might increase so that rollershutters do open…
- Or kids playing with a light torch lighting the sensor so that shades go up and down after few minutes not lighting the sensor any longer. Very funny game I could imagine.
Anyone an idea how to overcome this drawback? Something with percentage change over time? or lux value must be lower X lux for Y minutes to close/open shades?
Thanks for your ideas.
