I'm not a professional here, but I think you can use the Wi-Fi connection to link the devices and create a network.
I use this with my color-changing smart LED light bulbs from Vont
. They are very easy to install and adjust to your personal needs. For example, I use them mostly to fall asleep easier. They can create a very calming atmosphere in the room by shining dim and soft yellow or green light, which calms down my mind and helps me fall asleep. But this is only one of the possible uses of these devices, and you can use them for parties or for creating your own home movie theater. It's all up to you.
