Product Description

The NOUS B1T smart switch, equipped with Tasmota open software, is designed for automatic and manual shutdown of electrical appliances. It allows remote control via a Wi-Fi network using a smartphone or personal computer through a web interface. The switch uses a wireless Wi-Fi adapter for communication and features a mechanical button, a status indicator light, an electromechanical relay, and supports the Matter protocol.

⚠️ ATTENTION: The connection of a smart socket with a Wi-Fi network cannot be guaranteed in all cases. Success depends on various factors, including the quality of the communication channel, intermediate network equipment, the mobile device's brand and 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 disassemble the product yourself. Diagnostics and repair must be carried out 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 away from children.

Design and Controls

The NOUS B1T features a mechanical button for manual control and an indicator light for status updates. It also includes UART connectors for device programming.

Terminal Marking

• 0 - Relay output terminal
• I - Relay input terminal
• S - Switch input terminal
• L - Live (110-240V) terminal
• N - Neutral terminal
• +12V - DC positive terminal
• GND - DC ground terminal
• DC+ - DC positive terminal

After installation is complete, the device is ready to use. Ensure the Wi-Fi network is stable and has a sufficient signal level in the chosen installation location.

Wi-Fi Connection

A smartphone or personal computer is required to connect the NOUS B1T switch.

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

1. Ensure the Wi-Fi network frequency range is 2.4 GHz, as the device is not designed for 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's not detected, perform a "RESET" as described in point 11.
3. Connect to the "tasmota-xxxxxxx" hotspot.
4. After 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.
5. On the displayed page, select your Wi-Fi access point and enter its password, then click "Save".
6. Upon successful connection, the inscription "Successfully connected to Wi-Fi" will appear along with your device's network address (e.g., 10.1.1.210).
7. Connect to your Wi-Fi network and navigate to the address provided in step 6.
8. Calibrate the device for power source monitoring. Instructions can be found at: https://tasmota.github.io/docs/Power-Monitoring-Calibration/
9. The device is ready for use. Templates and rules are activated by default.

Configuration and Integrations

The device configuration involves setting up templates and other parameters via the Tasmota web interface.

Template Configuration

The following template parameters are used for the NOUS B1T:

Template JSON: {"NAME":"NOUS B1T","GPIO":[544,0,1,0,32,160,1,1,224,0,0,1,1,1,0,1,0,1,1,1,0,1,1,1,0,0,0,0,1,1,1,0,1,0,0,1],"FLAG":0,"BASE":1}

Enter this template in the "Template" field, check "Activate", and save the changes.

Other Parameters

Users can configure:

• Web Admin Password
• HTTP API enable/disable
• MQTT enable/disable
• Device Name (Tasmota)
• Friendly Name 1 (Tasmota)
• Emulation options (None, Belkin WeMo single device, Hue Bridge multi device)

Resetting the Device

To reset the device to factory settings:

• Plug and unplug the device 6 times, leaving it on for the 7th time. The LED should start flashing, indicating it's ready to connect again.
• Alternatively, if you have access to the web interface, type "reset 1" in the console and press "enter".
