Wall switch Sonoff M5-1C-80 Wi‑Fi — single‑pole smart switch for in‑wall installation, 1 channel

Sonoff M5-1C-80 Wi‑Fi smart wall switch, 1 gang, mechanical button. The switch connects to the eWeLink app and supports voice control via Amazon Alexa and Google Assistant, local LAN operation, timers, scenes, device grouping, status sync and sharing. It communicates over 2.4 GHz Wi‑Fi, can replace a regular wall switch, fits into a standard electrical box or the Sonoff M-80 frame (frame sold separately), and includes an adjustable-brightness LED indicator for easy locating in the dark.

Advantages

The Sonoff M5-1C-80 provides reliable remote and local control of lighting and appliances using the eWeLink ecosystem and voice assistants. Mechanical quick-response buttons remain usable in gloves or by elderly users and support two-way or multi-way control when paired with accessories such as the Sonoff Scene Controller R5. The device offers consistent appearance with NSPanel, optional integration with DW2-WiFi sensors for scene automation, and can operate without cloud access via configurable LAN support.

Recommendations

Use only with compatible Sonoff devices and a stable 2.4 GHz Wi‑Fi network. Ensure wiring is performed by a qualified electrician and verify voltage and current limits (max. 10 A, 100–240 V AC). For reliable smart-scene behavior without cloud access, enable local LAN support in the eWeLink app.
