Unreliable

Constantly needs resetting despite SNA being hardwired to network and placed close to spa. Even after resetting may not always work. Extremely buggy.

Completely broken

This app is worthless. You’ll be mad you ever tried.

Not worth the cost

I purchased this option thinking it would be useful to monitor my hottub. The radio setup required me to have a Ethernet port to plug in the Digi adapter. The app doesn’t show proper information, and when changing my salt output it never matches the panel display. I don’t have confidence it reads the temp right and impossible to tell if it’s connected or providing “dummy” data. The round gauge doesn’t match the gauge on panel either after performing a salt test.

Basic

Would be great if you could choose light colors. My control panel went on my hot tub so I had to get the wireless app. Very basic.

Simply stopped working

Can’t control my spa anymore. For an expensive add on, with no API access, this is very disappointing.
