I’m completely out of the smart lights loop and I’m looking for light bulbs that allow me to set brightness, color temperature and possibly the color in general using HA.

I see a lot of people recommending zigbee bulbs, which is fine, I just need to buy a dongle, but I already have an isolated wifi network with no internet access that I use to control smart stuff from my home server, so something with wifi would be ideal. I want something that I can just screw in and control from my server with no proprietary apps needed for the initial configuration.

Can you give me some recommendations?

Thanks
