Smart Dimmer switch recommendation? - no neutral, no hub, 4 AMP min

Hi- So I currently have some overhead LED lights connected to Alexa via a Sonoff miniL2. However, that requires me to keep the physical switch always on in order to control them remotely and use the dimmer on the physical switch. I'd like to upgrade the dimmer switch to a smart switch, but it need the following: *No neutral required *Doesn't require a hub or can use the Zigbee hub integrated into our Eero system *Can handle 400+ watts *Preferably could also extend the one wired switch with a remote, non-wired switch.

There are a lot of options that come close, but can't find any that hit all the marks. Anyone have any recommendations?
