How to dimmer a HUE bulb

HI All,
i’d like to buy a hue bulb and i want to control with a dimmer and change the intensity. Is it possibile? In other words i don’t want to implement a switch (on/off).

Best regards,
Marcello

This is standard behaviour for hue.

that’s a good news. I need to buy the hub also in order to integrate to my hassio?

Yes, you will need to use the hub (or an open source alternative) to facilitate communication between homeassistant and the bulb.

suggestion for open source alternative?
