A:Answer Not sure if this will help, but wanted to make sure that you are trying to add the additional lights via Google Home on your phone and not using the C by GE app. I have this speaker and currently have 4 C by GE Sleep bulbs in my home that are currently connected and working. Granted I also have multiple Google Home Minis and a Home Hub throughout the house, but I believe the main thing that was needed was to make sure that I the used Google Home app on my phone to find and add the bulbs. Two of the C By GE bulbs are in rooms with the insignia speaker and no Google Home devices. I do believe that the C by GE bulbs connect via bluetooth and I think that was a limitation with this speaker, but using your phone and the Google Home app should help. On a side note, if you want to try a different bulb, I would recommend the WiZ bulbs, they are priced right and I have had better success with mine as they are wifi bulbs. Not sure if BB sells those as I got mine from a local warehouse store.
