Yep, unfortunately most of the pool gear like VSP pumps & SWG is proprietary - there are some efforts to reverse engineer the protocols but it's not for the average user. So... pick your poison and go with Pentair, Hayward or Jandy. Since you already have the Intelliflo then Pentair would seem logical for you.I'd like to remove a lot of this and replace it with something simple. I'd prefer something that is a bit more friendly and open. By that I mean it will work with more than 1 brand, but from reading that seems kinda of difficult in the pool world. If anyone has any suggestions let me know.
