I put all untrustworthy devices on my guest WiFi. My game consoles, e-readers, streaming devices, and Internet appliances don't need access to my privileged network, and they don't need access to each other. And if I were so inclined to buy smart bulbs, they'd get the same treatment. And, yeah, my guest WiFi password is kind of secret, but I routinely give it out to people who I only casually trust.
