One way to solve 3 and maybe 2 would be adding to the ecuation an ESP32/8266 and use it as an access point for the lamps. Then you might create any physical controls for the lamps or with some network magic add it to your infrastructure through a segmented network. I'm not sure if this can be done with an ESP alone (hence "network magic") or you could just use a second ESP connected to your private network and passthrough your commands via a serial port to the Lamp's ESP AP.

ESP32's are fairly cheap, easy to use and can even be programmed through micropython.
