Multiple SSIDs for IOT segregation
Many IOT residential devices are manufactured in China; many brands (example: Gosund) use Chinese cloud services where privacy concerns are well known . SSID partitions will allow customers to segregate IOT devices (and its backing Chinese cloud services) to a secure , isolated network. Please implement ; security is day one , job zero at Amazon which you are now a part of .
Rather than a separate SSID, it would be nice to have a Profiles setting that isolated devices assigned to that profile so they could only connect to the Internet (WAN) and not connect to any other devices the local network (LAN or WiFi). You could then put all your IoT devices in that Profile and know they can only phone home but not connect to any other devices.
