Is there a difference between P-PKG1W-WH and the P-PKG1W-WH-R (with the -R)?
I am guessing the '-R' might be a RETAIL packaging designator? Maybe for the big box stores like Best Buy, Home Depot, and Lowes?
Just a guess.
Ok good enough .. I just wasn't sure if it was a different model ...
This is what I found on Lutron's site for model numbers http://www.lutron.com/en-US/Products/Pages/SingleRoomControls/CasetaWireless/ModelNumbers.aspx
