Direct IP connection
Wi-Fi devices join the normal home IP network without a separate low-power mesh.
Bandwidth needs differ
Cameras need far more network capacity than a plug or switch.
Power consumption matters
Battery devices often benefit from lower-power networking technologies.
Router changes can be disruptive
SSID, security or network architecture changes can affect many direct-Wi-Fi devices at once.
Keep in mind. Compatibility is not permanent. Confirm the current manufacturer, platform and certification information before purchasing, resetting or migrating a device.
