Thermostat is easy to program daily and nightly temperatures, set and you're good to go. That's how we use it. Haven't used the vacation mode or the Geo mode, but probably will eventually. Happy so far at one month.
upgraded from an older carrier thermostat, so the installation was a hair difficult, and it took at least 12 hours to get the wifi to sync up with the app, however, it was worth the wait. unit operates great, the app works well to adjust the temp while I'm on my way home from work; and the upgrade even qualified for a credit from my utility company.
