Smart wall switch or relay module: which one?

Both make your lights smart, but they work differently. Here is how to decide.

Smart wall switches

A smart wall switch replaces the switch on your wall. Touch panels give a clean, modern look and let you control the light from the wall. Wireless wall switches and decorative covers add more choice in style.

Relay modules

A relay module is a small unit that adds smart control to a light or appliance you already have, without changing how the room looks. It is a good fit when you want to keep your existing switches.

DIY modules

DIY modules such as the S-Mate2 are designed for automation projects and work with compatible gateways.

Which is right for you?

Choose a wall switch if you want to upgrade the look and feel of your switches. Choose a relay module if you want to make existing lights smart with the least visible change.

Check before you buy

Both types depend on your wiring and the space behind the switch, and some need a neutral wire or particular wiring. Send us a photo on WhatsApp, and use an electrician for installation.

Examples: SONOFF TX Ultimate and T5 wall switches; SONOFF Basic Gen5 (R5) relay module with Wi-Fi and Matter; SONOFF S-Mate2 DIY module.
