Nous D4Z is a high-performance (3 x 120A) smart consumption meter equipped with a Zigbee Tuya chip for non-contact consumption measurement of three phases. The current converter device is compatible with the Tuya / SmartLife smart home APP. Can be paired with Nous or other Tuya / SmartLife Zigbee gateways.

It consists of an 18 mm wide main unit mounted on a DIN rail and three current transformers with padlocks (open / close). The device works as a professional three-phase energy meter and accurately measures voltage, current, power and energy in real time.

The most important information:

- Accurate energy measurement: 1% energy measurement accuracy,
- Two-way measurement (consumption / recharge), can also be used with solar systems
- Broad integrability: e.g. Amazon Alexa, Google Home, Zigbee2MQTT, Tuya Zigbee
- App: Nous smart app or Tuya Smart app
- High performance: for measuring up to 3 x 120A
- Simple DIN rail installation in an electrical cabinet
- Smart home protocol: Zigbee
- Gateway: Tuya Zigbee gateway, e.g. A Nous E1 gateway is required for its remote control and integration into the smart home system.

Thanks to the Nous D4Z, you can measure the power of three-phase electrical systems without breaking the circuits to be measured, since you have to snap the three current transformers onto the three phase wires to be measured to start the measurement.

With its use, you can comfortably monitor the phase-to-phase load of the electrical network, as well as the voltage and current consumption levels.

A Tuya Zigbee compatible smart meter requires a Nous E1 or another Tuya Zigbee gateway, coordinator, or hub to connect the smart meter to the Zigbee network.

Main features:

- Real-time monitoring
- Easy setup
- Alert notifications
- Two-way measurement
- 1% energy measurement accuracy
- Flexible connection options
- Zigbee communication
- Two-way measurement: Measurement of performance and energy flow in terms of both consumption and production
- Real-time monitoring: Real-time monitoring of important electrical data such as voltage, current and power
- Simple installation: a monitoring module that can be mounted on a DIN rail and connected to compact split-core current transformers (CTs), requiring only 1 mW of power.
- Local automation:

What can the D4Z meter be used for?

- Energy consumption monitoring for apartments
- Energy consumption monitoring for small businesses: cafe, restaurant, shop, etc.
- Electrical monitoring for commercial buildings and infrastructures: commercial buildings: office, hotel, shopping centers, etc.
- Electrical monitoring for industrial energy efficiency projects
- Dynamic load balancing and grid backfill prevention for solar systems: in addition to monitoring the total energy consumption of the house installed on the main input circuit, real-time monitoring of the bidirectional power flow can provide inputs for dynamic load balancing (DLB) and minimize solar grid output.
