Thank you all for replying.? I wasn't expecting this much feedback but I appreciate all your feedback.
It good to know that even though the Jandy RS adaptor isn't made or supported by Jandy anymore that it may still work.? And IMHO, assuming that it still works, it is really the better solution than using the cloud base solution.? And now there appears that someone is making an after market one. Just do a google search for "jandy rs serial adapter" and you will find the first hit is for one being sold on Amazon.? A little pricey at $890 but it may be a good alternative.? Also search github for Jandy and you will find several open source projects using it.
