SunSmart Cloud 4+

Do not bother with this app or the associated hardware. This expensive option never makes the wifi connection to the spa. Mine is only twenty feet away with no obstructions and will only work, and then only about 5% of the time, if it is hung out of a window. Totally useless for remote access.
Even if there is a wifi connection the app itself has basic flaws. The reset of the clearray lamp and the outer filter will never reset from zero days remaining. Other functions are without explanation and the whole app is extremely sluggish.
This expensive option is so bad it is borderline pure theft. I should have realized given my experience with different Sundance spa dealers who were very reluctant to promote it, even though in theory it would sell itself, given the (broken) promise of added convenience.
This wifi package will do serious damage to the reputation of Sundance spas if not recalled and corrected.

And they don’t support you. Unfortunately if you are reading this you already bought a Sundance and paid for the WiFi. Ugh. Never again! And good luck calling either Sundance or the local warranty guys. The man sent for warranty told me he only does things that involve real tools.

App has not been updated in more than 2 years. I’m on iOS 11 and only temperature function works reliably. Resetting of Clear Ray and Outer filter countdowns do not work. Disappointing functionality for the $300 I paid.
