Can a smart switch work without a neutral?

A few models can with a bypass capacitor for incandescent loads. Most LED loads need a neutral. We add one.

Wi-Fi Smart Switch Installation

WiFi smart switches installed properly — with the neutral that South African wiring usually doesn't have at the switch.

Sonoff, Shelly and Tuya switches are great — provided they have a neutral. Most SA homes don't. We add one cleanly and properly.

Add neutral at switch, install smart relay or smart switch, commission.

Neutral wiring done properly — not a wire-nutted bodge.
