I’m in the process of building a new house and would like to add the following functionality:
When the ambient lighting is low (i.e. during nighttime), when a motion sensor is triggered I would like certain lights to come on dimmed (say 10% of total brightness).
After 5 minutes they should go out.
Here is the kicker - if someone stays in a room and adjusts the lights to full brightness, I would like those lights to stay on at the user selected brightness. The lights should turn off after 3 hours if the user forgets to turn them off before retiring for the evening.
How can I get item 3 to work without the 5-minute nightlight delay shutting off the lights. On the same token, how can I make sure the brightness isn’t dimmed back to 10% when the motion sensor detects movement even though someone wishes to stay in the room and has manually selected the brightness?
Thanks for any help - I’m new to this and can’t seem to find this information via search.
