## Summary description

Nous D2T is a DIN-rail smart switch based on an ESP32 module, running Tasmota firmware and rated for 20 A switching. Designed for electrical distribution panels, it provides remote control and automation of circuits, integration with home automation platforms via Tasmota, and compact DIN-form factor for mounting in consumer units and control cabinets.

## Long description

Nous D2T DIN 20A is a compact smart switch built for DIN-rail mounting in electrical distribution panels and control cabinets. Based on an ESP32 module and running Tasmota firmware, the device provides remote switching, local control, and integration with common home automation platforms that support Tasmota. Rated for switching currents up to 20 A, the module fits standard DIN rail spaces and is intended for circuit-level control where space efficiency and firmware flexibility are required.
Advantages
The Nous D2T combines an ESP32-based controller with open Tasmota firmware to enable flexible integration and customization. Its DIN-rail form factor and compact dimensions allow installation in consumer units without occupying excessive space. With a 20 A switching rating the module supports a range of household circuits and lighting loads. Tasmota firmware provides local control, MQTT and HTTP interfaces, and compatibility with many home automation systems, reducing dependence on cloud services.
Suitable for
Remote control and automation of lighting circuits
Switching of heating or ventilation loads within the 20 A limit
Integration into home automation systems via Tasmota (MQTT/HTTP)
Installation inside consumer units, distribution boards, and control cabinets
Key specifications
Control module: ESP32-based microcontroller
Firmware: Tasmota for local control and automation integration
Maximum switching current: 20 A
Mounting: standard DIN-rail (TH35) compatible housing
Interfaces: network connectivity and protocol support provided by Tasmota (MQTT/HTTP)
Form factor: compact module designed for electrical distribution panels
How to use
Install the Nous D2T into a standard DIN rail inside a consumer unit or control cabinet following local electrical regulations and with the power disconnected. Connect the live and neutral conductors to the switch terminals as indicated in the product wiring diagram, and ensure protective earth and circuit protection devices are in place. Configure network and Tasmota settings via the device’s web interface or serial console, set up MQTT or HTTP endpoints if integration with external automation systems is required, and test switching using the local controls before returning the circuit to normal operation.
Usage recommendations
Use appropriate upstream overcurrent protection sized for the connected circuit and ensure the switched load does not exceed the 20 A rating. Place the module in an electrically safe enclosure and avoid exposure to moisture and excessive heat. When integrating with automation platforms, secure MQTT connections and follow Tasmota documentation for firmware configuration and updates.
