I have a 2007-ish Sundance Optima inground spa with CPU board 6600-018.... was wondering if there was an upgrade path to being able to have it controlled/connected to wifi?
the newer CPU boards seem to have this feature/add on option. I'm told mine is incompatible with the Sundance app/wifi....
i cant see having to replace the entire spa....maybe just the cpu board? The factory has not been very responsive on this point.
