Actually the link itself talks about ZigBee and Philips hue bulbs specifically. Appears that association can also be used with ZigBee bulbs. It seems to me that I can:
- Turn on/off from the switch directly - this is possible already
- Turn on scenes from the switch directly - this is also possible once the lights turn on
- Turn on using Google assistant - not possible fully as it goes directly into the warm white of Philips hue
- Turn off using Google assistant - possible
- Tell Google to set lights in porch (all my lights are in the porch) a certain color - not possible
