There’s no bigger reason than security to connect all smart home devices to a separate network. Somebody finding their way into a home’s personal network can have lifelong repercussions. News reports about hackers gaining control of a smart device like a baby-monitoring camera have happened, which is a significant security concern. An especially skilled hacker could use that access to launch a denial of service to the device and any other device connected to the same network.
It doesn’t have to be something with a camera, either. Digital invaders could use something as benign as a smart speaker to wreak havoc. If bad actors can gain control of those smart devices, they can lock owners out of their laptops or, worse, gain access to sensitive documents saved on their computers. This leads to stolen identities and computers being held for ransom. An isolated network for smart devices adds a layer of protection, as it limits the devices connected to the main network you use for your phone and computer.
