Smart bulb mode for S210, S220
When the switch is in smart bulb mode, tapping the paddles doesn't switch the relays, so it doesn't cut the power to the bulb. They act like a S200 - just as a controller. Long pressing the paddles do cut the power by switching the relays.
This is useful in installations where it is important to be able to cut the power, for example if the smart bulb needs to be replaced.
Many other brands - like zooz - offer this feature.
