This is a really poor app. At best it can be given one star because you can set the vent fan & turn it on & off which in my case eliminates the need for a ladder in the attic. It does not connect to your network so you cannot control it outside the home. Using wifi you either connect to the fan or you home network. The best choice is to connect via Bluetooth after updating the firmware. It even lacks the ability to refresh without closing & reopening the app. I expected better from GAF. Hopefully they will improve it over time but based on my brief encounter with their support staff I doubt it.

A lot of these negative reviews are unfounded. Folks, this is not a smart device like your nest thermostat. A roof vent typically has a manual control for thermostat and humidistat. This is something you set and forget in most cases, or adjust only seasonally. This simply keeps you for having to go into the attic to do it. There is no reason to adjust the settings while away from home, or on a frequent basis. If you want to monitor the temp of your attic you need a different device, preferably near the attic floor. In a tall attic there is a huge difference between the roof deck and the attic floor. The app is a bit confusing, esp with two fans. Yes you must log into the fans WiFi network, make your adjustment, then log back into your home WiFi. This is secure. Do you want someone hacking into your router through your attic fan? No. I hope GAF can improve the app and the fan, but they just need to make the marketing more clear. For me it’s been great. No ladders.

I’m a roofing contractor and we just installed two wifi vents. Once they were powered they showed up on the list of available wifi connections. You can only connect to one at a time but, my phone connected to them no problem. Then, the app found the connected device no problem. I could turn the vent on manually or turn it on with the thermostat setting. I made settings for the first one, then I switched over the connection to the second one. I turned it on and off through all avenues, and made settings for it. Then I switched back to the first one again and, the setting were still as I put them. I updated firmware immediately so, hopefully these things will continue to be this awesome for years into the future!

First off I am NOT affiliated with GAF or their app developer. That being said, I’m confused as to why there are so many negative reviews on this product and the app. I installed the gable vent fan using rubber insulator washers placed between the four “L” brackets and wall studs. It is located directly above my home office and I can barely hear it when it’s on (and yes, my hearing is fine!) The app works as advertised so I’m wondering why so many negative reviews? I’m very happy with my purchase and I’m really glad I took a chance and ignored all the negative feedback. This is a good product that is reasonably priced.
