Nothing extraordinary. It's a programmable thermostat with WiFi. Requires you to use it's network name instead of your home WiFi network name so it's difficult to set up. Haven't tried to access it from outside, so not sure it works from 5G networks.
These wifi thermostats works great - super simple to use and program and no problems with connectivity or otherwise. it's great to be able to program the thermostat when not home also
Easy to program and the app works well on my iPhone. The geography feature that starts or stops the system depending on the owners physical location (I.e. within two miles of residence) is very nice.
Works perfectly with my dual fuel system. Also works great with Alexa. Couldn’t be happier. I paid a local HVAC company to install it and glad I did. Not exactly like “old school” thermostats that I’ve installed myself in my other homes.
