WiFi DIN Smart Switch 1-63A with Protection and Energy Meter

Smart Wi-Fi Switch NOUS D6, DIN, 1–63 A, with Protection Functions and Energy Monitoring

NOUS D6 is a DIN rail-mounted smart Wi-Fi switch combining remote electrical circuit control, energy consumption monitoring and adjustable electrical protection functions. The device measures voltage, current, power and consumed energy, and automatically disconnects the load when the configured limits are exceeded.

This smart DIN switch is designed for single-phase electrical networks in homes, apartments, offices or other premises. It is installed in an electrical distribution board on a standard 35 mm DIN rail and allows you to remotely switch a selected electrical circuit on or off using your phone, set timers and create operating schedules.

NOUS D6 operates within an 80–300 V AC voltage range, supports adjustable current from 1–63 A and loads up to 7 kW. Integrated protection functions respond to dangerous overvoltage or undervoltage, overcurrent and leakage current. Once the electrical network parameters return to the configured limits, the automatic reconnection function can restore the power supply after the selected delay time.

Why Choose This Product?

• Multiple functions in one device: NOUS D6 combines the functions of a smart switch, voltage relay, leakage current protection and energy meter.
• Electrical network parameter monitoring: monitor voltage, current, power consumption and consumed electrical energy in real time.
• Protection against voltage fluctuations: the device disconnects the load when the mains voltage exceeds the configured safe limits or drops below them.
• Overcurrent protection: the adjustable overcurrent threshold helps protect the electrical circuit and connected appliances from excessive loads.
• Leakage current monitoring: if leakage current exceeding the configured threshold is detected, the power supply is automatically disconnected.
• Automatic reconnection: once the electrical network parameters return to normal, power can be restored automatically after the configured delay time.
• Remote control: use the app to check the circuit status and switch it on or off even when you are away from the electrical distribution board.
• Energy consumption analysis: consumption data helps identify circuits that use the most electricity and plan energy consumption more efficiently.
• Compact installation: the narrow 19 mm housing takes up minimal space in the electrical distribution board.

Who Is This Product For?

The NOUS D6 smart DIN switch is suitable for users who require remote electrical circuit control, protection against mains faults and more accurate energy consumption monitoring.

• Home and apartment owners who want to monitor total energy consumption or the consumption of an individual electrical circuit.
• Holiday homes and remotely managed properties where it is important to check and control the power supply using a phone.
• Workshops and garages where the load of a selected equipment circuit needs to be monitored and controlled.
• Offices and commercial premises where electrical circuit operating schedules need to be configured and energy consumption monitored.
• Smart home users who want to integrate the electrical distribution board into a TUYA-based control system.

Practical Applications in an Electrical Distribution Board

• Monitor the voltage, current, power and energy consumption of an entire premises or a selected electrical circuit.
• Remotely switch off the power supply to a holiday home, garage, workshop or other property.
• Set an operating schedule for the circuit so that connected equipment operates only during selected hours.
• Use the protection functions for equipment that is sensitive to excessively high or low mains voltage.
• Set the permitted current limit according to the wiring, load and electrical installation design of the protected circuit.
• Use the app to check whether power to the circuit has been restored after a mains failure.

More Control and Fewer Unexpected Electrical Faults

Mains voltage fluctuations, overcurrent or leakage current can pose a risk to connected equipment and electrical installations. NOUS D6 continuously monitors key electrical parameters and automatically disconnects the load when conditions outside the configured limits are detected.

Real-time measurement data available in the app helps you quickly identify unusually high loads or energy consumption. Adjustable protection thresholds allow the device to be configured for a specific electrical circuit, but they must be selected by a qualified electrician according to the installation parameters and applicable safety requirements.

Technical Specifications

Frequently Asked Questions (FAQ)

How does the NOUS D6 smart DIN switch work?
The switch is installed in an electrical distribution board and continuously monitors the circuit voltage, current, power and electricity consumption. When a dangerous electrical network condition is detected, the device automatically disconnects the load.

Who should install the NOUS D6 switch?
The device must be installed and configured in the electrical distribution board by a qualified electrician. Incorrect connection or incorrectly configured protection thresholds may create a risk of electric shock, fire or equipment damage.

Does NOUS D6 measure electricity consumption?
Yes. The device measures voltage, current and power in real time and also records consumed electrical energy. The data can be monitored in the mobile app.

What electrical protection functions does this switch provide?
NOUS D6 provides protection against overvoltage, undervoltage, overcurrent and leakage current exceeding the configured threshold. Specific thresholds must be configured by a qualified specialist according to the electrical installation.

Does the switch reconnect automatically after a mains fault?
Yes. When the electrical network parameters return to the configured permitted limits, the automatic reconnection function can restore power after the selected delay time.

Does NOUS D6 work with a 5 GHz Wi-Fi network?
No. The device connects to a 2,4 GHz Wi-Fi network supporting the IEEE 802.11 b/g/n protocol. A stable and sufficiently strong wireless network signal must be available at the installation location.

Where can the NOUS D6 switch be used?
The IP20-rated device is intended for installation in a suitable electrical distribution board located in dry indoor areas. It is not protected against water and therefore must not be installed outdoors or in humid environments without an appropriate protective enclosure.

How do I restore the factory and network settings?
Press and hold the device button for approximately 5–7 seconds. After restoring the settings, the switch will need to be reconnected to the Wi-Fi network and app.

Choose the NOUS D6 smart Wi-Fi DIN switch if you want to combine remote electrical circuit control, energy metering and adjustable protection functions in a single device. When professionally installed and correctly configured, the device helps you monitor the electrical network more conveniently and respond more quickly to potentially dangerous changes in its parameters.
