You'd want any interface like this to only be accessible over JTAG/serial in order to help prevent bad actors from recruiting the devices for Mirai-style botnets. Additionally, DNN NLP AI really isn't possible on these devices.

The ESP8266 microchip is very popular for use with consumer IoT, because it includes not only a microprocessor with full TCP/IP software stack included, but also WiFi hardware that's compatible with most consumer WiFi systems, all on a 5mm x 5mm x 1mm IC. However, it doesn't even have enough computation power to implement 802.11x WiFi certificate authentication for standard enterprise WiFi environments. There's no hope for implementing an NLP DNN AI on chips like this. You'd "need" to upgrade from a $2 microchip to a $100 IoT Edge AI chip like Coral or Jetson, and now each of your $30 IoT light switches would cost $130 instead and consume much more power.

You could instead have a pretty standard telnet access with 'help' functions like most *nix programs have, but enabling any kind of telnet/SSH is often a big security risk with IoT devices.

You don't want any devices accessible over the normal internet. Set up a Tor Hidden Service, require some authentication at the bastion host to your internal network and you're good to go.
