Yeelight 3 gang switch

Hey, can someone tell me if this 3 gang switch can control 1 smart lamp and 2 normal lamps? Or it doesn’t work like that and needs all smart devices.
Single button switch has a switch for traditional or smart lamp ( the red switch inside the gang) but on the pictures I see only 1 so I guess its all 3 gangs as traditional or smart and can’t distinguish them like that.
Anyone knows?
