Very easy to initiate the WiFi network. We moved into a two story home and can either use the app or ask Alexa to change either or both temperature settings.
I wanted a thermostat that I could control when I was out of state and this one does that. It’s very basic and does not offer the option to switch from air conditioning to heat automatically. Having said that, it achieves the purpose I purchased it for.
Thermostat was in use for 18 months, but hadn't set up internet access for the thermostat. Reasonably easy to use and like other similar devices requires an app. It is convenient and works as promised.
