Sonoff M5-2C-80 Wi-Fi wall switch, 2 circuits, model M5-2C-80

Sonoff M5-2C-80 is a 2-gang Wi‑Fi smart wall switch with mechanical buttons, designed to replace a standard wall switch and integrate with the Sonoff smart home system. It provides local and cloud control via the eWeLink app, supports voice assistants Amazon Alexa and Google Assistant, and can work with IFTTT and Sonoff accessories such as NSPanel, R5 scene controller and DW2-WIFI sensors. The switch uses 2.4 GHz Wi‑Fi and offers configurable local LAN support for operation without a cloud server.

Advantages

The Sonoff M5-2C-80 combines a familiar mechanical button feel with smart features: remote control from smartphone, voice control, timers, scene creation and device grouping. It supports multi-way control when used with the Sonoff Scene Controller R5 and integrates with NSPanel for touch-screen control. An adjustable LED indicator improves visibility in the dark, and the quick-response buttons are suitable for users wearing gloves or for elderly users. Its compact design and matching colour scheme allow seamless integration with other Sonoff devices.

Optionally pair with NSPanel for touch-screen control, with R5 for multi-way switching or with DW2-WIFI sensors for automated behaviours. Configure timers, schedules and groups in the app as required.

Recommendations

For safe operation, have the switch installed by a qualified electrician and ensure the connected load per gang does not exceed 5 A. Use 2.4 GHz Wi‑Fi for device pairing and keep firmware and the eWeLink app up to date. Do not expose the device to moisture or install it in environments outside the specified temperature and humidity ranges.
