The NOUS D2T is a smart Wi-Fi relay module designed for installation on DIN rails in electrical panels. It is intended for smart control and energy measurement of electrical devices and circuits. With a maximum capacity of 20A, this model is suitable for controlling most household circuits and loads.

The open-source Tasmota firmware offers flexible configuration options and integration capabilities. It allows full local operation of the smart relay unit, with a local web-based configuration interface available. Thanks to the Tasmota firmware, the device also supports the MQTT protocol, enabling easy integration with most open smart home platforms such as Home Assistant.

Compatibility with the Matter standard allows the NOUS D2T to be used with popular smart home platforms like Apple HomeKit, SmartThings, Google Home, Alexa, and eWeLink.
