I have seen other threads on here and I want to make certain I understand. We just had our pool built(less than 2 months). We have the Jandy Aqualink PDA firmware 7.0. We want to upgrade to the I Aqualink that will be compatible with Alexa. (our entire home runs on Alexa) I thought looking through the posts we only needed the IAqualink 2.0-A antenna. The poolbuilder states we need the additional board otherwise it only is on/off and has no control like our PDA does. This seems to conflict to the literature from Aqualink. Do we need to spend $1000 or will the $400 antenna and download of app give the same performance. I wan to get this for my husband for father's day so any info is appreciated. Shhhh it is a surprise (well only if in budget).
