It functions....usually – Fan Smart Sync Review

One star because it does do the basic things like turn the light or the fan on and off. Anytime you go to set a timer, you have approximately 3 seconds to spin the wheel to set the amount of time on the timer and if you have not confirmed your selection at the end of 3 seconds the app crashes and disconnects you from the device you were attempting to control. The app has been this way for over a year. Numerous complaints have been ignored. No updates to the app. Obviously, customer service is not a priority; though, they likely do not even have a customer service department judging by similar feedback left on here.
