Have a Model 8840. Have tried repeatedly to have the app connect to the thermostat but no luck. Keeps telling me to delete the thermostat and try again. Still can't find thermostat. The app totally sucks. Or maybe it's the thermostat that sucks. Not totally sure.
Just purchased 8620W thermostat The thermostat says lost Internet connection and app will not connect to the thermostat. Professional installer could not figure it out. Used 4 difderent wifi routers (linsys, netgear, asus, isp router) Tried in dual band mode and 2.4 only. Joins wifi fine but wont connect from there. No support either
Love the control Had to read the directions a couple times to get connected but now I just love the control. I can access my thermostat from anywhere and it has essentially all the controls including changing the schedule. The only function I hope they add soon is finger print instead of password.
Just purchased 8476w, works perfectly
Sparse with Communication Issues Interface is sparse and non-intuitive but functional. App fails to successfully connect to thermostat on first attempt...very repeatable. Please fix issues and improve user interface for higher review score. Allow days to be grouped for easier programming. Updates through Google Play do not describe changes or fixes. App does not provide user feedback means to developer. (8/31/16 update: connectivity issues still exist. Does Aprilaire read these reviews?)
Doesn't work Thermostat disconnected from Internet. No way to reconnect to the internet. Only thing to do is delete the thermostat from your profile and try to sync it all back up but it still won't connect to the internet.
Minor bug fixes and enhancements.
