I have two stairway switches (one at top of stairs and one at bottom) that work together (double pole?) and I want to replace both with motion sensors. What kind of sensors would I need to buy and how would I configure the wiring? TIA!!

You need motion sensors that are three way.

Ah, thank you!

Depending on how the 3-way wiring is set up, you can reconfigure it and use single pole switches too. Somewhere here I have a wiring diagram I rew up for someone so they could copy a job I did a while back. I will see if I can find it.
