What do you call a wifi Switch that will provide continuity or no continuity on its output - NO LOAD - Control only

[DPressm]

I have a bathroom fan with a moisture detector that turns it on and off. It also has a control circuit to turn it on/off when moisture is not connected. This is a no voltage/no current circuit.

I want to add a parallel control circuit that would of course be no load no current that I can turn on/off by Wi-Fi (Alexa) - I realize that operating current (5v or 12v) would also be needed. I need to know what to look for on Amazon to get a switch that operates like as described. I link(s) below that shows one I think will work.

Thank You
