Home Assistant: Philips Hue Tap Dial Light Brightness Control (through the native Hue Bridge integration)

• Control a light's brightness with the rotary dial of the Hue Tap Dial switch with this blueprint.
• No Zigbee hardware required.
• It only handles the dial rotation without the button presses.
• You need to create a new text helper. Inside that text helper, you have to type in the light entity ID.

Based on this blueprint from the forums.
