Purchased this little heater specifically for it's ability to be controlled with my phone via Wi-Fi. Couldn't have been easier to set up, Heater has been up and running for over a month without losing its Wi-Fi connection. Highly recommend! Note: Wi-Fi set up must be done using 2.4GHz, NOT 5GHz! Most home Wi-Fi routers have the ability to switch back-and-forth between the two. If directions are followed, this little heater is everything it says it is and more!
