Pulled this from the Amazon description.
"Two or more lights can be controlled by a phone at the same time. You just need to change user-name and set template for each light. When setting one light, make sure another light wifi button is off, then set another light. When all the lights are setted a template and a different name, you can control lights together by a phone."
It did say to contact them if you had any trouble setting up the lights.
