wireless control

I currently have a very outdated controller, AquaLogic. Like everyone else who has or had this system it hardly ever keeps time or looses 8 hours of time then becomes non existent. Without replacing the entire system at the moment is it possible to wire in a Wifi switch to just the filter pump...

I have an Easytouch 8 setup with a wireless controller(UWC) and one wired controller (UIC). All were setup/installed in 2016. The controlled did have a spill into the spa and it was replaced under warranty (only the handheld remote portion, not the wired antenna). I don't know if that matters...
