It’s by using Matter.
You add your Hue Bridge to Aqara with Matter. Then all your Hue stuff appears in Aqara app. Please don’t ask me details, just search “add Hue Bridge to Aqara” and you’ll get there.
The bug applies to scenes and automations.
Fiddling about I discovered that you can tell which actions will work or not by using the preview toggle.
To try, create new scene, add a Philips Hue light, choose “set brightness to”, then toggle preview on. When you drag the slider and let go, the brightness will change.
If you try to add “set color and brightness” and toggle preview, when you drag sliders around, no response from the bulb.
