For initial setup, there's tons of different methods, though I don't know about light bulbs specifically, but the different IoT devices I've set up have included:
* WiFi direct
* Setup over Bluetooth
* Device broadcasts for autoconfig, get settings from a gateway or local master node.
* Static configuration entered in the IoT gateway based on
the physical port the device is plugged into.
* Dip switches
* Initial configuration needs to plug into a PC via USB or serial port and a custom windows program.
* Cryptic sequence entered via IRDA remote control.
Thanks, I can see these would be relevant for many different devices. Actually you've reminded me how many VoIP phones use DHCP for this, which would be great for any device that supported it.
