Yeah, give it a whirl. There's only two kinds of memory in an Athom bulb: The RAM that is built into the ESP MCU (temporary, fast -- like RAM in a PC), and the flash ROM (permanent, much slower -- like an SSD in a PC). Data in RAM doesn't survive for even a moment without power. Data in flash should be good for years and years with or without power.
