Are you talking about using it with a Wyze Bulb, or using it through IFTTT to turn on some other bulb?
With Wyze Bulbs, you can do this through Wyze’s native rules. No IFTTT needed. Choose the camera as a trigger and select “Detect a person.”
If you’d like to do it through IFTTT, it can’t be done yet. I doubt they’ll ever add total feature parity to third-party services like IFTTT and Alexa and Google, in terms of triggers. But I added a wishlist item for a Wyze Virtual Switch, which would essentially enable total feature parity, without the need for them to directly add every trigger. Vote for it if you’d like to see it happen.
If Wyze added a virtual switch functionality, you could make a rule in the Wyze app that tells the virtual switch to turn on when a person is detected. Then you’d have a separate trigger in IFTTT that turns on third-party bulbs whenever the virtual switch is activated.
