As stated, the lights (all of them, which are 9 different ones) turn blue after about 5 minutes on any other color.
I had the same issues with Nanoleaf Bulbs and this is why I stopped using the system. I am tech savvy but this is beyond annoying, it renders the entire SmartThings sytem unuseable because lights are one of the anchors of the system.
Also, I tried disconnecting it from SmartThings and hooking up the skill on Alexa. Works perfectly, but then I can not use my SmartThings system with any automations.
I wish it were that simple. No hunches. No Alexa routines.
I connected to a new Samsung account and no problems.
I think I have a ghost in my system. Keep in mind this happened with Google Home connected to Smartthings as well, the same exact color, with NanoLead and TPKasa
