With Philips you don't need to only make an account, you'll need yet another "Bridge" device (costing about as much as your lamp give or take) to get all the features.
Correct. I have a Home Assistant SkyConnect coordinator (zigbee) connected to my home server to control my RGB lighting. Fuck Phillips though, they plan to make registration mandatory under the pretence of "security"
Which is funny, cause if people cared about security they wouldnt have all those stupid useless devices in their house demanding internet connections and trackable accounts.
