Smart Relay Bidirectional 3-Phase Energy Meter WiFi TUYA

Bidirectional Energy Monitoring | Remote Switch | PV Statistics

100A | WiFi + Bluetooth | Tuya / Smart Life | DIN Rail Mount

▶️ Intelligent Energy Management

• Tuya Ecosystem: Full control via Smart Life / Tuya Smart app (Android / iOS) – monitor consumption from anywhere in the world.

• Voice Control: Compatible with Google Home and Amazon Alexa – control power with simple voice commands.

• Intuitive Visual Signaling: The screen backlight changes depending on the operating status. Blue confirms the relay is on, while red indicates it is disconnected, ensuring excellent readability even in dark rooms.

▶️ Comprehensive Photovoltaic Analytics

• Bidirectional Measurement: Precise recording of energy taken from the grid and energy fed back (PV production).
• Full Data History: Clear charts of consumption and production on a daily, monthly, and yearly basis.
• Statistics Center: Access to detailed event logs and advanced reports directly in the app.

▶️ Smart Control and Savings

• Limits Under Your Control: Set consumption thresholds (e.g., 100 kWh for a given period).
• Perfect for Landlords: The function allows for effective cost management and monitoring of energy limits in rented premises.

▶️ Advanced Safety System (Alarms)

The device monitors your installation by tracking a number of parameters:

• Power Supply: Overvoltage, undervoltage, phase loss, and phase reversal.
• Load: Overcurrent, overload, and voltage imbalance between phases (%).
• Physical Safety: Temperature and leakage current alarms.

▶️ Personalization and Reliability

• Power State Management: Define behavior after power restoration (ON, OFF, or restore last state).
• Smart Delay: Adjust the power-on delay time after supply return or after a critical alarm clears.
• Settings Protection: Access lock with an administrator password.

▶️ Switch Functionality

• Remote ON/OFF: Cut off the power to the entire installation with one click on your phone.

• Automation: Time schedules, countdown (Timer), and cyclic operation.

▶️ Key Functions Description

1. Real-time Monitoring – View voltage, current, and power for each of the three phases in real-time.
2. Relay Status Memory – Memory of the relay state; after power failure, the device will return to the last mode (ON/OFF) or default state.
3. Inching Function – Ability to turn on power for a short, defined time (pulse).
4. Bluetooth Pairing – The Bluetooth module allows for instant discovery and addition of the device to the application.
