A lot of the automatic toilets in public restrooms don't have handles anymore. Manually flushing one involves finding and pushing a button or intentionally activating the sensor.Guess I wouldn't consider that "smart" since that's literally a basic light sensor and a switch. You can get ones that literally just fit over the handle and the switch just rotates a cog that pushes the handle down as it rotates around. 1980s tech. Maybe even 1970s.
