This is what's happening with Philips Hue light bulbs, switches, etc. First, you could do what you want. Then you needed their stuff to activate all features. In a couple of months, you'll have no choice but to use an account. Luckily, they still use the Zigbee protocol, so you can set up a Zigbee USB dongle with mosquitto and zigbee2mqtt or Home Assistant and do whatever you want.
