Frequently Asked Questions
Q: Does this 3-phase smart energy meter work with both WiFi and Zigbee simultaneously?
A: The meter is available in WiFi or Zigbee variants. Please select the version that matches your existing smart home infrastructure. The Zigbee version operates on the Zigbee 3.0 standard at 2.4GHz and requires a compatible Zigbee hub/gateway, while the WiFi version connects directly to your home network.
Q: Can this energy meter be used with solar or renewable energy systems?
A: Yes. Thanks to its bidirectional metering capability, this energy meter can measure both energy drawn from the grid and energy exported back to it — making it an excellent choice for properties with solar panels or other renewable energy sources.
Q: Is Modbus RTU support useful for home users, or is it mainly for commercial applications?
A: Modbus RTU is primarily used in industrial and commercial environments — such as building management systems (BMS), SCADA platforms, and energy management systems — but advanced home users and prosumers who want to integrate the meter into a local automation server (e.g., Home Assistant with RS485) can also take advantage of it.
Q: What app do I use to monitor and control this smart energy meter remotely?
A: This meter is compatible with the Tuya Smart and Smart Life apps, both available free on iOS and Android. From the app, you can view real-time data, check historical consumption, set tariff schedules, control the relay switch, and configure automation scenes.
