I have a CC2531 running and have paired mostly Xiaomi device to date. I have some Sylvania SMART+ 73741 RBG ceiling lights that I just installed. What is the proper process to pair them? They are listed on the supported devices page, but no steps are provided on pairing. I have enabled join and nothing happens and the devices themselves have no button. I brought one down right next to the coordinator just to be sure and cannot seem to get anything to appear in the logs. Have tried the latest and latest-dev releases of Z2M as well. Anyone know what I am missing ? Thanks!
