Just moved to a new house. I had a couple Sengled color wifi bulbs conected to my network at that house. The new house I am not using those bulbs, not connected to the network. My Smartthings keeps finding them and adding new devices to the system thus Alexa then adds them also. I checked my Netgear Nighthawk router and the bulbs are not in the access control as connected. I delete them from both the Smartthings and the Alexa just to reappear agian later. How can I stop this?
