RE110P+

Do you guys sell the RE110P+ ? I can only find the RE110P but I see a link to a PDF showing the RE110P+ for GE systems. Is there a difference?

There is no difference. My understanding is that a typo, that they are working to correct, on some of the material added the β€œ+” to the end, but β€œRE110P” is how Resolution Products officially refers to their GE compatible Motion Detector.
