This app still has a lot bugs. It usually works (but not always) on my older android devices. However it does not work at all on my galaxy s8. Lately the hub has been disconnecting from my wifi and reverting back to its own wifi connection. Quietcool support services is also non responsive. I have called and left messages as well as sent several emails with no response.
I could not possibly be more unhappy with this. The app hardly ever works. It either says it's updating (endlessly) or says my network controller is unreachable. It's useless. We paid $1000 for this fan and it's basically nonfunctional due to this.
Looks like it's time for a class action lawsuit. We've been told that the app would be fixed months ago and still not a dam thing done.
Ok, I agree. The app is very buggy. I have been struggling with it like everyone else: Super annoying "updating, waiting..."!!!Finally, I think I have figured it out: Router settings. This is with the latest firmware update (1.03.16). 1) make sure 2.4 GHz is set at Auto for channel and 20 MHz for channel Width; 2) Set quite cool wifi device IP address as static on your router. To help you identify which one (oui: Newport Media, Inc.) After these changes (who knows which one is more important), I can quickly find the fan from multiple devices and control it simultaneously (I know!). Anyway, good luck. p.s. I have Tomato Router control. So all these settings are available.
It locks up and says "Updating, please wait". Now it will not work at all on my Galaxy S8. Stuck in the updating loop. Uninstall and reinstall will not fix. I tried another WiFi fan controller with same results. Odd thing it works on my Galaxy S6 work phone. That provides its not the controller hardware. Totally useless on S8.
Had so many bugs when I first got the app but now it is amazing. Love my QuietCool fan!
Various bug fixes. Updated the included fan firmware version.
