I have front curtains and back curtains.
Curtains open at sunrise, after illuminance rises above 200
Curtains close at sunset, after illuminance falls below 100
I have some switches that influence the curtain behaviour.
Film switch on - front and back curtains closed.
Coolback switch on - back curtain closed.
Coolfront switch on - front curtain closed.
And of course curtains open when the switches are off (If it is between sunrise and sunset, and no other switches are on).
Thank you in advance!
