SONOFF ZBM5-1C-80W – Smart Zigbee Wall Switch

The SONOFF ZBM5-1C-80W is a modern 1-channel smart wall switch designed for convenient control of lighting and other compatible electrical devices. Thanks to its support for Zigbee 3.0, it enables reliable connectivity with a compatible Zigbee gateway and control via the eWeLink app.

A major advantage of the BM5 switch is its flexible installation, as it can be wired with or without a neutral wire. This allows it to be used even in older electrical wiring where a neutral wire is not available in the switch box. When used without a neutral wire, a minimum connected load of 3 W is required.

Through the app, you can control the lights remotely, set timers and schedules, and include the switch in various smart scenes and automations. Voice control via compatible voice assistants is also supported.

When connected with a neutral wire, the ZBM5 can also function as a Zigbee router, helping to improve the coverage and stability of the Zigbee network. A Detach Relay mode is also available, which is particularly useful with smart bulbs, as it allows the physical switch and the relay to operate independently.

The switch is also suitable for more advanced smart home systems and can be connected to Home Assistant via ZHA or Zigbee2MQTT using a compatible Zigbee adapter.
