I have a new WIFI thermostat that loses it's internet connection at least once every week to two weeks requiring the thermostat to be manually disconnected and reconnected to the mounting plate to restore the internet. Obviously the purpose of the WIFI thermostat is to be able adjust it remotely but with no connection this is not possible. I can't tell why the internet drops out. The thermostat manufacturer wants me to open PORT 443 to hopefully fix this condition. Is there any problems with doing this?
