Details

The European Nous brand's new Nous B3T two-gang smart relay module with consumption meter has an embedded Wi-Fi chip, and can be used to control two separate circuits (e.g., multi-gang light) or a bidirectional motor (e.g., shutter motor, shade motor, curtain motor). It is a Matter-compatible product.

Nous ships the B3T relay module with factory-installed Tasmota firmware, making it primarily recommended for users and integrators of open-source smart home systems and those seeking solutions compatible with Matter hubs.


What is Tasmota firmware?

TASMOTA is an open-source firmware increasingly used as a factory installed software for smart home devices. It supports manufacturer-independent and cloud-independent local control, and local, secure data storage. Since Tasmota is open-source, the community continuously develops and improves it, enhancing security and reliability.

It supports various communication protocols, such as MQTT and WebSocket, ensuring wide compatibility with different platforms. TASMOTA devices can easily integrate with various smart home hubs, such as Home Assistant, OpenHAB, Domoticz, and Node-RED.

The Tasmota firmware offers a local web administration interface on the devices where various settings can be configured. Although it does not provide a "factory" app, several third-party applications are available to control and manage the devices. Home Assistant, OpenHAB, and other smart home platforms also have mobile applications that can integrate and control TASMOTA devices.


The Nous B3T WiFi smart switch module can be used as a two-channel relay switch or a single-channel curtain/shutter/motor controller module.

The device features a built-in ESP32 MINI-1 module with 4MB flash memory and comes with pre-installed Tasmota firmware, allowing easy integration with various smart home systems, such as Home Assistant.

The B3T module supports 100-240V AC or 24-30V DC power supply and connects to the Wi-Fi network via built-in 2.4 GHz Wi-Fi chip.

The module's special feature is its two-channel power measurement, making it suitable for controlling motorized curtains or shutters.

Since the B3T operates with Tasmota firmware, it is not compatible with Nous' own application but rather with open-source solutions, such as Home Assistant or other systems supporting the MQTT protocol.

Thanks to its small size, it fits into standard-depth wall mount boxes behind traditional light switches.

It has an input for the light switch, allowing the "smartened" wall switches to remain usable as before.

It works in local mode without internet connection and factory cloud access, and can be set for scheduled on/off.

It's a Matter standard compatible solution, thus compatible with Apple HomeKit and SmartThings (when connected to a Matter hub). When connected to a Matter hub or Home Assistant, it supports voice control with Amazon Alexa and Google Assistant.
