## Long description

Nous D3T DIN 25A is a DIN-rail smart switch based on an ESP32 platform with preinstalled Tasmota firmware. Designed for mounting inside distribution panels, the device enables Wi‑Fi control of electrical circuits and switching of loads up to 25 A. The unit provides remote on/off control, scheduling and status reporting over a local network, and is compatible with common home automation systems that support Tasmota-based devices.
Advantages
The Nous D3T combines a high current switching capability with the flexibility of open Tasmota firmware, allowing both simple Wi‑Fi control and deeper integration through MQTT and HTTP interfaces. DIN-rail mounting saves panel space and simplifies installation inside electrical cabinets. Built on an ESP32 controller, it offers stable wireless connectivity and enough processing headroom for automation tasks. The device is suitable for replacing mechanical relays where remote control, scheduling or automation is required.
Suitable for
Smart lighting control in residential and small commercial installations
Remote switching of appliances and electric heaters within the rated current
Integration into MQTT- or HTTP-based home automation systems
Scheduling and timed control of circuits from a central panel

How to use
Install the Nous D3T on a standard DIN rail inside the distribution panel following local electrical regulations and ensuring power is disconnected during installation. Connect line and load conductors to the terminal blocks according to the wiring diagram, and apply power. Configure the device by connecting to the local Wi‑Fi network and use the Tasmota web interface or your chosen home automation controller to set up MQTT, HTTP endpoints, rules and schedule entries. Verify switching operation with test loads within the 25 A rating before full deployment.
Usage recommendations
Use appropriate circuit protection (circuit breakers or fuses) sized for the load and compliant with local codes. Avoid exceeding the 25 A continuous switching rating; for inductive or motor loads, account for inrush currents and select protective devices accordingly. Keep firmware updated via Tasmota tools and secure network access with strong credentials to maintain reliable operation.
