I’ve lost the ability to change the color of my OSRAM Lightify A19 lamps through the SmartThings app. I don’t know when this feature stopped responding, since I’ve returned home from a number of weeks on the road. The feature is still shown in the app, but the lamp does not respond to a command to change color. I’m guessing that a firmware update to the hub probably goofed up this function. I haven’t tried removing the lamps from my hub and adding them again. I will try that, but wanted to first see if anyone else is experiencing this problem and if there is another solution. Thanks.
