NOUS D3T is a smart Wi-Fi relay module that can be installed on the DIN rail of an electrical cabinet, specially designed for smart control and consumption measurement of electrical devices. The module's maximum capacity of 25A makes it suitable for controlling the largest household circuits and consumers.

The open source Tasmota firmware offers flexible configuration and integration options. It enables the fully local operation of the smart relay module, for which a local web configuration interface is available on the device. Thanks to the Tasmota firmware, the device also supports the MQTT protocol, so it can be well integrated with most open source systems, such as the Home Assistant. Note: Tasmota firmware is not a commercial product and only limited community technical support is available.

Thanks to its compatibility with the Matter standard, the Nous D3T can also be used with popular smart home platforms such as Apple HomeKit, SmartThings, Google Home, Alexa or eWeLink.

Other compatible platforms: AWS IoT, Domoticz, Homebridge, HomeSeer, IP Symcon, KNX, NodeRed, nymea, OctoPrint, openHAB, Otto, IOBroker, Mozilla WebThings Adapter, Tasmohab, Homematic ip. More information about Tasmota's integration options: https://tasmota.github.io/docs/Integrations/
