Hi, I have the same problem with the YLXD50YL. How can we go about getting the devices supported? If it was a driver, I'd happily take a look at the code.
Ok thanks, I did send in a support ticket just last week. I will tag Mr. @mike.maxwell here so he can see your original request. Hopefully we will get an update soon.
Also, if you post the model number like danirtoma did "Yeelight YLXD41YL Ceiling Lamp" and cc mike with the full log error they might be able to add the device for you. I would like get those lamps as well, if they are added.
