I don’t have neutral wire for lights, is there some “fake” dimmer now, so that it could be on/off using hw switch (not requirement) and control the dimming using zigbee rule?
The only one I could think of at the moment is the innovelli blue series zigbee dimmer.
They are the best in class and they can do pretty much anything and everything that you want a dimmer switch to do.

I think yeelight is currently the best option since BT support was added to home assistant, but i do not think any work with zigbee binding which is what i thing i meant by rule years back
