Sorry… I should have said that.
What I wanted was for my stairway lights to come on as soon as someone stayed walking up or down them.
I tried a monoprice motion sensor, but there were two problems. 1- it was slow. I could be halfway up the stairs before it reported or even detected motion. 2- it would detect motion of people walking by the stairs through the foyer.
At the time that was my only motion sensor. I’ve sense started using the Enerwave ceiling mounted sensors and the iris sensors. Both are very good. But I still didn’t use them in the stairs.
Here is what I did… I built low light level led lamps and placed them on the stairs railings. They are dim, but bright enough to see at night. They aren’t noticeable during the day. They cost about 25 cents to run 24/7/365.
The stair lights are on automations with mode changes.
While this want my ideal fix in the beginning, I have found it to be much better than what I actually planned.
This is exactly what I did…
