Frequently Asked Questions
Q: Does this 3-phase smart energy meter work with both WiFi and Zigbee?
A: Yes — this Tuya energy meter is available in both a WiFi (2.4GHz) version and a Zigbee 3.0 (2.4GHz) version. Choose the connectivity type that best suits your smart home or building automation setup. Both versions are fully compatible with the Tuya Smart and Smart Life apps.
Q: Can this meter be used with solar panels or bidirectional energy systems?
A: Absolutely. The bidirectional metering capability allows the device to measure both imported and exported power, making it well-suited for grid-tied solar installations where you want to track energy flowing both from and back to the grid.
Q: What is Modbus RTU and why is it useful?
A: Modbus RTU is a widely used serial communication protocol in industrial and building automation systems. Support for Modbus RTU means this energy meter can be integrated with PLCs, SCADA systems, and other automation infrastructure — greatly expanding its usability beyond standard consumer smart home setups.
Q: What current range does this energy meter support?
A: The meter supports a current range of 0.25A to 80A, making it versatile for residential, light commercial, and small industrial three-phase electrical systems operating at AC 3×110/190V or 230/400V.
