When this app works it works OK, when it’s not working it does not work at all. I have the temp and humidity both set for their lowest settings and the humidity and the temperature are both higher than the settings and it does not turn on. I have to constantly go in and turn it on manually. Very Inconvenient. I think I am going to bypass the whole system and put a manual switch and that will be more reliable. I would not buy this unit again if I had to rely on the Wi-Fi. Bypass it in the unit works great

Does the job

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.

Worked like a charm!

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!
