Operation Manual
NOTE: Tasmota is not a commercial product and support is limited. Users must be willing to independently investigate and resolve potential issues. Detailed information on connection, changing settings, and modifications is presented on the website: https://tasmota.github.io/docs/
Description
The NOUS B2T smart switch with Tasmota open software installed is designed to organize automatic and manual shutdown of electrical appliances. It allows for remote access via a Wi-Fi network, using a smartphone or a personal computer via a web interface. Communication with the switch is configured via a Wi-Fi network using a wireless Wi-Fi adapter. The switch is equipped with a mechanical button and a light indicator of the device's status. It features 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, as it depends on many conditions, including the quality of the communication channel, intermediate network equipment, the brand and model of the mobile device, and the version of the operating system.
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 subject to mechanical loads.
- Do not use chemically active and abrasive detergents to clean the product. Use a damp flannel cloth instead.
- Do not overload the specified capacity, as this may cause a short circuit and electric shock.
- Do not disassemble the product yourself; diagnostics and repair of the device must be carried out only in a certified service center.
- Please contact the seller for a replacement if there is damage caused by shipping.
- Please insert the plug into the outlet in proper condition and away from children.
- For safety reasons, insert the plug fully into the outlet when in use.

Assembly
Installation Procedure:
Follow the electrical diagrams and marking instructions for proper installation.
Connection
Electrical Diagrams and Marking:
110-240V Connection: A diagram shows a blue smart switch with terminals labeled L, N, S, and O. Input wires are shown connecting to L and N. Output wires connect from O. A wire connects to S, indicating a switch input.
24-30V Connection: A diagram shows a blue smart switch with terminals labeled L, N, S, O, GND, and DC+. Input wires from a 24-30V DC source connect to DC+ and GND. Output wires connect from O. A wire connects to S, indicating a switch input. L and N terminals are not used.
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
When the installation is complete, the device is ready to use. Importantly, make sure that the Wi-Fi network is stable and has a sufficient signal level in the chosen installation location.
Wi-Fi Network Connection Procedure:
- Make sure that the frequency range of the network to which the device will be connected is 2.4 GHz, as the device is not designed to work with 5 GHz Wi-Fi networks.
- Connect the device to the network. On the PC, the access point "tasmota-xxxxxxxx" should appear in the list of networks. If the access point is not detected, perform a "RESET" according to point 11.
- Connect to the hotspot "tasmota-xxxxxxx".
- After connecting to the access point, the browser should automatically open and navigate to the link 192.168.4.1. If this does not happen, open the browser manually and enter 192.168.4.1 in the address input field.
- On the open page, select your Wi-Fi access point and enter its password in the field below, then click "Save".
- When the connection is complete, the inscription "Successfully connected to Wi-Fi" and the address of your device on the network will appear.
- Connect to your Wi-Fi network and go to the address that was specified in point 6.
- You will need to calibrate the device for power monitoring. You can find instructions here: https://tasmota.github.io/docs/Power-Monitoring-Calibration/
- The device is ready for use. The template and rules are already activated.
Configuration and Advanced Settings
Template Parameters:
The template must be entered in the "Template" field. Check "Activate" and save the changes. Example JSON template: {"NAME":"NOUS B2T","GPIO":[544,3200,1,8160,32,160,1,1,224,0,0,1,1,1,0,1,0,1,1,1,0,1,1,1,0,0,0,0,1,1,1,0,1,0,0,1],"FLAG":0,"BASE":1}
Other Parameters:
Configure settings such as Web Admin Password, HTTP API, MQTT, Device Name, Friendly Name, and Emulation options.
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 is ready to connect again.
- Alternatively, if you have access to the web interface, type "
reset 1" in the console and press "enter".
Matter Protocol Connection:
To connect the device to smart home systems using the Matter protocol, read the following information: https://tasmota.github.io/docs/Matter/
