FYI Phillips hue is not vendor locked, and does not require the internet. They're not cheap though.
Zigbee2mqtt and a cheap zigbee dongle is all you need really. You could add home assistant for a better interface but there is no need to involve Phillips or the Internet. One of the huge advantages of zigbee imo.
One other really cool thing is they have a wireless switch that is powered by the act of pushing the button.
