OPERATION MANUAL

Description

The NOUS B3T smart switch, equipped with Tasmota open software, is designed for the automatic and manual control of electrical appliances. It allows for remote access via a Wi-Fi network using a smartphone or a personal computer through a web interface. The switch utilizes a wireless Wi-Fi adapter for communication and features a mechanical button, a status indicator light, an electromechanical relay, and support for the Matter protocol.

ATTENTION: The reliable connection of a smart socket with a Wi-Fi network can vary based on numerous factors, including the quality of the communication channel, intermediate network equipment, the specific mobile device model, and the operating system version.

Precautions

• Read this manual carefully.
• Use the product within the temperature and humidity limits specified in the technical data sheet.
• Do not install the product near heat sources, such as radiators.
• Do not allow the device to fall or be subjected to mechanical loads.
• Do not use chemically active or abrasive detergents for cleaning. Use a damp flannel cloth instead.
• Do not overload the specified capacity, as this may cause short circuits and electric shock.
• Do not attempt to disassemble the product yourself. Diagnostics and repair must be performed by a certified service center.
• Contact the seller for a replacement if there is damage caused by shipping.
• For safety reasons, insert the plug fully into the outlet when in use and ensure it is kept away from children.

Design and Controls

Assembling

Installation procedure:

1. Connect the switch as shown in one of the electrical diagrams provided.

Terminal Marking:

• 0 - Relay output terminal
• I - Relay input terminal
• S - Switch input terminal
• L - Live (110-240V) terminal
• N - Neutral terminal
• GND - DC ground terminal
• DC+ - DC positive terminal

Connection

When the installation is complete, the device is ready for use. Ensure that the Wi-Fi network is stable and has a sufficient signal level at the chosen installation location.

A smartphone or personal computer is required to connect the NOUS B3T switch.

Procedure for connecting the switch to the Wi-Fi network:

1. Ensure the Wi-Fi network frequency is 2.4 GHz, as the device does not support 5 GHz networks.
2. Connect the device to the network. The access point "tasmota-xxxxxxxx" should appear in the list of networks on your PC. If it is not detected, perform a "RESET" as described in point 11.
3. Connect to the "tasmota-xxxxxxx" hotspot.
4. Upon connecting to the access point, a browser should automatically open to 192.168.4.1. If not, manually open a browser and enter 192.168.4.1 in the address bar.
5. On the displayed page, select your Wi-Fi access point and enter its password, then click "Save".
6. After connection, the message "Successfully connected to Wi-Fi" will appear, along with your device's network address.
7. Connect to your Wi-Fi network and navigate to the address provided in step 6.
8. For power monitoring, calibration is recommended. Instructions can be found at: https://tasmota.github.io/docs/Power-Monitoring-Calibration/
9. The device is now ready for use. The template and rules are pre-activated.

Configuration and Advanced Settings

The device configuration involves applying a template. The JSON template for the NOUS B3T is:

{"NAME":"NOUS B3T","GPIO": [544,3200,1,8128,32,160,1,1,224,225,0,1,1,1,161,1,0,1,1,1,0,1 ,1,1,0,0,0,0,1,1,1,0,1,0,0,1], "FLAG":0,"BASE":1}

This template must be entered into the "Template" field in the device's web interface. Ensure "Activate" is checked, and then save the changes.

Special Modes (e.g., Blinds):

To enable "Blinds" mode, activate the following commands:

• SetOption80 1
• ShutterRelay1 1
• Interlock 1,2
• Interlock ON
• SwitchMode1 4
• SwitchMode2 4

Resetting the Device:

To reset the device to factory settings:

1. Unplug and plug the device in and out 6 times. On the 7th time, leave it plugged in. The LED should start flashing, indicating it is ready to connect again.
2. Alternatively, if you have web interface access, type reset 1 in the console and press Enter.
