Nous D4Z - Tuya Zigbee smart DIN-rail three-phase power meter (3x120A)

The Nous D4Z is a high performance (3 x 120A) smart power meter equipped with a Zigbee Tuya chip, supporting three-phase contactless metering. It is compatible with the Tuya/SmartLife smart home APP. It can be paired with a Nous E1 or other Tuya / SmartLife Zigbee gateways.

It consists of an 18 mm wide DIN-rail mounted main unit and three pieces of clamps (openable) / current transformers. The unit operates as a professional three-phase energy meter and accurately measures voltage, current, power and energy in real time.

Highlights:

• Accurate energy measurement: 1% energy measurement accuracy,
• Bidirectional measurement (consumption / recharge), can be used with solar systems
• Wide integration: e.g. Amazon Alexa, Google Home, Zigbee2MQTT, Tuya Zigbee
• App: Nous smart app or Tuya Smart app
• High power: measure up to 3 x 120A
• Easy DIN rail mounting in electrical cabinets
• Smart home protocol: Zigbee
• Needs a Tuya Zigbee Gateway for smart home integration and remote control.
  

With Nous D4Z allows you can measure the power of three-phase electrical systems witt contactless install, you only need to put the three current transformer clamps onto the three live wires.

You can conveniently remotely monitor the phase load, voltage and current consumption levels of the electrical network.

The Tuya Zigbee compatible smart meter requires a Nous E1 or other brand of Tuya Zigbee gateway, coordinator or hub to connect the smart meter to the Zigbee network.

What is the Tuya / SmartLife smart home platform and app?

Tuya is a popular cloud-based smartwatch platform that provides integrated solutions for various smartwatch tools and applications. The platform enables quick and easy pairing, remote control and management of devices through a single APP interface. Tuya, also known as SmartLife, provides users with a comprehensive smart home ecosystem, including devices from multiple manufacturers.

Supports voice control, remote access and automated processes (reports). The Tuya platform has cloud-side integration with a range of other smart home ecosystems, such as Amazon Alexa, Google Assistant and SmartThings, so Tuya devices can be used on these platforms as well. Tuya, like its global platform eWeLink, is also a cloud-based system, but the quality of available Tuya devices is more scattered.

In the Tuya offering, European Nous is a Tuya device vendor with a solid quality offering. Its tools can be used with Nous app or with the standard Tuya app.

Key features:

• Real-time monitoring
• Easy setup
• Alarm notifications
• Two-way measurement
• 1% energy measurement accuracy
• Flexible connection options
• Zigbee communication
• Bi-directional measurement: measuring power and energy flow for both consumption and production
• Real-time monitoring: real-time monitoring of important electrical data such as voltage, current and power
• Easy installation.

What can the D4Z meter be used for?

• Energy consumption monitoring for homes
• Energy consumption monitoring for small businesses: café, restaurant, shop, etc.
• Electrical monitoring for commercial buildings and infrastructures: commercial buildings: offices, hotels, shopping centres, etc.
• Electrical supervision for industrial energy efficiency projects
• Dynamic load balancing and grid back-feed prevention for solar PV systems: in addition to monitoring the total power consumption of the house installed on the main input circuit, real-time monitoring of bidirectional power flows can provide inputs for dynamic load balancing (DLB) and minimize solar power grid output.
