Hi, Welcome to Just Answer. My name is XXXXX XXXXX would be glad to assist.
What is the make and model of the sensor? With only 4 leads, sounds like a single pole and not a 3way.
let me look it up
it is a single pole, so we need to get some more info on your wiring
At the location you wish to install this sensor, how many wires in the box? and what colors?
all wires connected to the switch you are replacing and any wires that are in the same cables as those that attach to the switch
3 ways have 3 terminals, one black screw and 2 brass
need wire color on each
and at each switch
now, the whites that are in the same cable as the red and blacks, are they just connected to other whites in each box?
Switch you are replacing------The sensor Hot wire connects to the Old switch Hot (black screw). The sensor white connects to the the group of whites in the box (neutral). The ground of course connects to all the other grounds, and the sensor Load connect it to the red going between the 2 switches.
If you will read what I posted
Now, the other switch that will no longer be used
connect the red that goes between the 2 switches to the red on the black screw
Then cap off all the other on the switch
The red that is on the black screw is the load to the light
you are just connecting it all the way back to the sensor load wire
on 3 ways, the black screw will either have power or the light. You identified which one had power, so the red is to the light at the other end
that is why it is identified, it is called the Common
The other 2 brass are called Travelers
correct. But dont think it is always that easy. Sometimes all the wires are in the same box. Then you send the power to the last switch and back again
There are many ways to connect the wires, but end result is---power on one switch black screw and the light on the other ones black screw
You see mis labels all the time, here is a way to do a proper circuit directory on a panel
they can be fun and sometimes down right tough
