Wall touch smart switch Sonoff ZBM5-1C-80W, Zigbee, 1-channel, 80W

The Sonoff ZBM5-1C-80W is a Zigbee wall-mounted touch smart switch with one control channel and support for installations with or without a neutral wire. It integrates with the eWeLink app and compatible Zigbee gateways to provide remote control, schedules, scenes and voice control via Alexa or Google Home. The switch supports detach relay mode so smart bulbs can remain powered when the wall switch is turned off, and it is compatible with open-source systems such as Zigbee2MQTT and ZHA for broader smart home integration.

Advantages

The Sonoff ZBM5-1C-80W combines touch control and Zigbee connectivity in a compact white housing made of PC and CRS. It supports low minimum load operation (3 W without neutral), offers a single-channel design suitable for one lighting circuit, and works with a range of SONOFF Zigbee gateways (iHost, NSPanel Pro, ZBBridge-U/P, ZBDongle-E/-P). It provides reliable remote control through the eWeLink app, voice control via Alexa and Google Home, and interoperability with open-source platforms for flexible automation.

• Homes with or without a neutral wire

How to use

Install the Sonoff ZBM5-1C-80W into a compatible wall box following local electrical regulations and the included user manual. Connect live and neutral wires according to your installation (the device supports both with and without neutral). Pair the switch with a compatible SONOFF Zigbee gateway or Zigbee coordinator, then add it to the eWeLink app to enable remote control, scheduling and scenes. Use the touch panel for local control or voice commands via a linked Alexa or Google Home account. If required, configure detach relay mode so connected smart bulbs keep network power when the switch is off.

Recommendations

Use the switch with a compatible SONOFF Zigbee gateway (for example iHost, NSPanel Pro, ZBBridge-U/P or ZBDongle-E/-P) to enable full remote and voice-control features. Verify bulb compatibility and minimum load requirements (3 W without neutral) before installation. Follow local wiring codes and, if unsure, have installation performed by a qualified electrician.
