I have 5 Hue lights working, till my roommate decided to turn one off physically by using the switch and not using the app. I looked at the app and it said unreachable, so I deleted it and tried to add it via entering the serial number, but didn’t work. I installed the bulb on a lamp that’s less than 1 feet from the hue bridge and used the lamp finder, but it didn’t work. I tried to do the one via programming/api where I was able to do everything BUT connect the freaking bulb. I’ve been in this for hours now and I need help. BTW, I did notice that as I was unscrewing the lightbulb, with the power still on, it flickered a little. PLEASE HELP!!!
