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.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this energy meter be used with solar or renewable energy systems?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is Modbus RTU support useful for home users, or is it mainly for commercial applications?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What app do I use to monitor and control this smart energy meter remotely?\u003c\/h4\u003e\n\u003cp\u003eA: This meter is compatible with the \u003cstrong\u003eTuya Smart\u003c\/strong\u003e and \u003cstrong\u003eSmart Life\u003c\/strong\u003e apps, both available free on iOS and Android.
