Really enjoy this smart beautiful light, but one thing you need to make sure your router is set to 2.4Ghz in order to connect your smart light to WiFi. For those who has a 5Ghz router which is a combine 2.4Ghz frequency, and sharing the same Wifi in both channels,  just go into your router setting, change your 2.4Ghz channel name to a different one then the 5Ghz. I wish they will make a 5Ghz smart bulb in the future.
