The Nous D4Z is an advanced smart energy meter (3 x 120A) equipped with a Zigbee Tuya chip, supporting three-phase contactless measurement. Compatible with the Tuya/SmartLife smart home app, it can be paired with Zigbee Nous E1 gateways or other Tuya/SmartLife gateways.

It consists of a main 18 mm unit, designed for DIN rail mounting, and three openable clamps/current transformers. The unit functions as a professional three-phase energy meter and accurately measures voltage, current, power, and energy in real-time.

• Accurate energy measurement: 1% energy measurement accuracy.
• Dual measurement: consumption/recharge measurement, suitable for solar systems.
• Extensive integration: e.g., Amazon Alexa, Google Home, Zigbee2MQTT, Tuya Zigbee.
• Easy installation: suitable for DIN rails in electrical panels.
• Smart home protocol: Zigbee.

With the Nous D4Z, you can measure the power of three-phase electrical systems without contact by simply placing the three current transformer clamps on the three active conductors. You can easily monitor remotely the phase load, voltage, and power consumption levels of the electrical network.

The smart meter compatible with Tuya Zigbee requires a Zigbee Nous E1 gateway or another brand to connect to the Zigbee network.
