So i have 2 smartswitches - one for a ceiling fan, one for the attached ceiling lights. Is this an add-on situation or can I use the smart fan control and a smart light?

Title says it all - apparently they used to have the ceiling fan/lights controlled by one switch and an outlet controlled by one switch. But then decided to have the ceiling fan and lights be controlled with one light switch each (and constant power to the outlet).

I may be over thinking this - but can I use two smartswitches in this case? Would I use an add-on switch for one? Or can i keep my fan switch?
