Stairwell 3-way with sensor switches

Greetings! I have recently researched how to wire a stairwell on 3-way switches with two motion sensor switches. It took awhile to find the answer that made sense but I now have one question.
The way i found to do it was basically wire each sensor as a single pole switch and running both switches to the single wire running power to the light. This way motion either at the top of the stairs and motion at the bottom of the stairs will activate the switch and turn on the light.
My question is this: is there any problem with both switches sending current at the same time to the light? I dont see how its an issue but I thought I should ask just in case.

Stairwell 3-way with sensor switches

As long as both switches are on the same breaker there should not be a problem. It is just two switches in parallel and either one will turn on the light.


Do not PM with questions that can be asked in a forum. I will not respond.
