I have come across a smart light switch made by LightwaveRF which contains some electronics to turn on/off the lights, dim the lights and allow the user to control the lights remotely using a smart device or remote control.
The switch appears to generate its power from the incoming unswitched live wire in and the switched live wire out, there is no neutral required at the light switch.
This is one of a handful of similar switches powering electronics in the same way - without a netural - and I'm intrigued as to how it works.
Does anyone have any ideas as to how this works?
