I don’t have a Cam v3 or the Spotlight Kit, so I can’t see what IFTTT can control (though I’ve used IFTTT at times to interact with other Wyze devices, like Bulb Color and Plug Outdoor). I don’t have an answer, but I do have a question: How do you intend to trigger this event?
I’m asking because I think it’s an interesting problem, even though I don’t fully understand your particular use case, and I’m curious about what guidance the community might provide. Maybe I’ll learn something new!
