Bestway Smart Hub APK 2.1.92

5 stars: Had to run through wifi setup twice but it connected the second time. Very happy to have Wi-Fi functions for turning on and off heater, pump, and air. Hoping to use the scheduling function too, but haven't yet. Will update review if there's any issues.
4 stars: Easy to setup just make sure your connecting to your routers 2.4g. If your phone is connected to the 5g it won't connect. Check your wifi reconnect your phone to the 2.4 and retry. I was connected to my netgear06-5G so re-scanned connections and selected neatgear06. This work for me no issues. Hope it helps. 4* because I had to reconnect to my wifi. App works great no adds.
3 stars: I had no problems setting this up, I'm sure there's some step that may not be obvious to some that is causing all the negative reviews. However this app is missing two essential features: 1) notify me if the spa is off unexpectedly, like after a power outage, and 2) support a daily schedule so I can turn it on and off set hours every day and by day of week. Do that and you get 5 stars.
3 stars: Use this instead of the LAYZSPA app, which is useless. Would be nice to be able to set repeat timers or better still, scheduling. It is not easy to connect on Android, as the OS keeps disconnecting and hiding any wifi network without an internet connection. Took several tries last time.
