One of the new products from the European brand Nous is the Nous B2T 1-gang Wi-Fi smart relay with energy monitoring, which can be used for controlling and monitoring the power consumption of outlets or light switches when installed behind them, or for controlling any other device up to 16A. Matter-compatible product.

Nous supplies the B2T relay module pre-installed with Tasmota firmware, making it especially recommended for users and integrators of open-source smart home systems, as well as those seeking solutions compatible with Matter hubs.



What is Tasmota firmware?

TASMOTA is an open-source firmware increasingly used - even factory pre-installed - as the base software for smart home devices. It allows cloud-independent local control, supporting manufacturer-independent, local, secure data storage. As Tasmota is open-source, the community continuously develops and checks it, increasing security and reliability.

It supports various communication protocols, such as MQTT, HTTP, and WebSocket, ensuring wide compatibility with different devices. 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 for different settings. It does not offer a "factory" app, but several third-party applications assist in controlling and managing the devices. Smart home platforms like Home Assistant, OpenHAB, and others also have mobile applications to integrate and control TASMOTA devices.


The Nous B2T WiFi smart switch module can be used as a one-channel relay switch and energy monitor. The device features a built-in ESP32 MINI-1 module with 4MB flash memory and comes with pre-installed Tasmota firmware, enabling easy integration with various smart home systems like Home Assistant.

The B2T module supports 100-240V AC or 24-30V DC power supply and connects to the Wi-Fi network via the built-in 2.4 GHz Wi-Fi. The module's special feature is its one-channel power measurement, making it suitable for monitoring the consumption of controlled devices and controlling them based on consumption data.

Since the B2T 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 outlet boxes behind traditional light switches. It has an input for the light switch, allowing the smartified wall switches to remain usable as before.


It operates in local mode without internet connection or factory cloud, and it can be scheduled.

It is a Matter-compatible solution, 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.
