Wiz bulbs use ESP-NOW (so that the Wiz remote can communicate with them). They also have an ESP-WROOM-02 inside (a package integrating an ESP-8266EX).

The fact that they use ESP-NOW means they can be controlled (theoretically) by any ESP* that has ESP-NOW support. So far, folks have only managed to go the other way—to intercept remote key presses [0]—but I imagine it won’t be long before they suss out control of the bulbs.
