I believe the Inovelli Blue Series dimmer switch does exactly this. I have it networked through some zigbee usb controller I bought and is entirely managed via Home Assistant. I haven’t tested it non-networked but I don’t think there would be any issue using the functionality directly from the switch.

Maybe I’m misreading the only plot that mentions dosing numbers anywhere. It looks like the largest dosing group is getting 3mg/kg/day. That’s a lot scaled up to a 100kg person (like 10x a normal gummy for example).
