Nous B5Z ZigBee MINI Smart Switch Module (1 channel, with PM)

OPERATING MANUAL

1. DESCRIPTION

The NOUS B5Z ZigBee Mini Smart Switch Module (hereinafter - the switch) is designed to organize automatic and manual shutdown of electrical appliances in the room, through remote access via the Internet, using a smartphone or tablet with the Nous Smart Home application installed. Communication with the switch is configured through a remote server using the P2P protocol, for which a wireless ZigBee adapter is used.

The switch is equipped with a mechanical button and a global indication of the device status. The device is equipped with an electromechanical relay.

It is intended for installation behind a wall switch or inside a mounting/junction box where space is limited, allowing you to make almost any switch or socket «smart» and integrate it into a Zigbee ecosystem. Zigbee 3.0 provides reliable wireless communication, low power consumption (up to 1 W), and support for mesh networking.

IMPORTANT:  You will need a Nous E1, Nous E7, Nous E15 or other Tuya compatible ZigBee gateway/hub to connect.

The connection of a switch to the Internet cannot be guaranteed in all cases, as it depends on many conditions: the quality of the communication channel and intermediate network equipment, the make and model of the mobile device, the version of the operating system, etc. (and may not always depend on the proper functioning of the switch or the ZigBee gateway/hub).

DEVICE FEATURES:

• Single channel, power consumption monitoring – (1 channel, with PM)
• Bluetooth control. After successful pairing of the app and the switch, even if the phone and the switch are offline, you can turn the smart switch on/off via the app at a distance of up to 10 meters.
• Manual control of the module. The module can be turned on/off by pressing the button on the housing. This allows you to check system operation immediately after installation.
• Group control. Multiple modules can be configured for group control, allowing you to control several devices with a single tap.
• Overload protection. Built-in protection against overcurrent – 8.5 A, overvoltage – 265 V, undervoltage – 85 V. If these limits are exceeded, the switch will automatically cut off the power.
• Power-off memory function. Allows the device to save and restore previous settings after a power outage or sudden power loss. You can set the behavior to OFF, ON, or Restore in the app.
