I did just like you said when I connected the 1st one. I updated the time zone on th app, then synced the time. Worked just fine, kept the time and all. Now on the 2nd one I synced the time and hit save just like the 1st one and it locked up, no blinking led (still connected to wifi) and all control of the light stopped in the app. I tried a factory reset, doesnt work, I deleted from the app, doesnt work. I check my wifi from my phone doesnt show up anymore, even when I unplugged my router, still couldnt see the lights internal wifi. The one step I forgot to do was update the firmware on the light when I got it connected, soIm assuming thats what went wrong, but now its stuck connected to my wifi but I can't see it no matter what I do. About to open the light and remove the battery, and see if thatll reset it, idk.
