I need to replace about 15 traditional wall light switches (no neutral wire) to turn on/off all lights with one operation inside the warehouse. And still maintain the ability to control each light individually.
The preference is not to set up a Wifi for each switch to reduce the number of devices connected to the network.
I am looking for some solution that will achieve this with either Bluetooth/RF or any other technology.
The warehouse dimensions are about 100ftx100ft with sheetrock walls.
Please assist.
