I am trying to find a starting point for making our home "smarter." I have two can lights over the fireplace that provides the primary illumination for the living room. Expect to get a Home Pod in the near future. I have been looking at Lutron smart dimmer switch conversion kit. Will it work with the existing bulbs? And, if I understand it correctly, I would not need a hub with this type of system. Appreciate any direction you can provide.
