Smart Switches and Modules (Zigbee, Wi-Fi)

Smart switches control your lights from your phone, by voice or automatically. There are three types – depending on whether you want to replace the switch, keep the existing one, or add a new one without cutting into the wall.

Three types of smart switches

• A wall switch replaces the old one – e.g. the glass BSEED Zigbee (with N) and BSEED Zigbee (no N) switches.
• A module behind your existing switch hides in the wall box and the switch stays – SONOFF ZBMINI R2, SONOFF ZBMINI-L2 or the 1-channel smart switch module.
• A battery wireless button sticks anywhere – SONOFF SNZB-01P or the MOES 4-button scene switch.

With or without neutral?

Many smart switches need a neutral wire in the wall box. If you don’t have one, choose a no-neutral model – e.g. the BSEED Zigbee switch (no N) or the SONOFF ZBMINI-L2. Leave the wiring to an electrician.

Zigbee or Wi-Fi?

Zigbee switches are low-power and the network is stable, but they need a Zigbee coordinator or gateway. Wi-Fi models connect straight to your router. Most of them also work with Home Assistant.
