The SONOFF ZBM5-2C-80W is a smart 2-channel wall switch from the SwitchMan ZBM5 series, designed for the separate control of two lighting circuits. It uses the Zigbee 3.0 wireless standard, which enables a stable connection to a compatible Zigbee gateway and integration into a smart home system.

One of the switch’s main advantages is its flexible installation, as it can operate with or without a neutral wire. It is therefore suitable for both newer and older electrical installations where a neutral wire is not available in the wall box. When installed without a neutral wire, a minimum load of 3 W is required.

If the switch is connected with a neutral wire, it can also function as a Zigbee router, helping to increase the range and stability of the Zigbee network. In this mode, it also supports the Detach Relay feature, which allows the physical button and the relay to operate independently and is useful when using smart lights.

Through a compatible Zigbee gateway, you can control both channels remotely, set timers and schedules, and create various smart scenes and automations.

The switch also supports integration with the Home Assistant system via ZHA or Zigbee2MQTT using a compatible SONOFF Zigbee adapter.
