Home energy monitoring designed to track consumption and solar generation in real time. OWON Energy Monitor brings bi-directional sensing and Tuya Smart integration, helping households see exported and imported energy and spot inefficiencies. Will it suit homes with solar or 3-phase/4-wire supplies?
⚡ At a Glance
- • Measurement Accuracy: Real-time readings of active power, voltage, current and power factor with ±2% accuracy
- • Best for: Homeowners with solar arrays and small businesses needing per-circuit visibility
- • Not ideal for: 3-phase 3-wire electrical systems without a neutral connection
Bi-directional sensing records energy imported from and exported to the grid. Data is delivered every two seconds via 2.4 GHz Wi-Fi and presented in hour, day and month charts.
Clear import and export readings - with bi-directional sensing
Bi-directional sensing measures energy flow in both directions, combining clamp current measurements with voltage sampling to calculate imported and exported kWh. Three clamps monitor up to three separate conductors, enabling generation versus consumption comparison on the same chart.
Solar generation and grid feed-in are visible side-by-side with consumption data, making it straightforward to confirm how much energy is being exported and how much is being used.
Live monitoring and app control - thanks to Tuya Smart and 2.4 GHz Wi-Fi
Integration with Tuya Smart uses a 2.4 GHz Wi-Fi connection to push measurements every two seconds, presenting Active Power, Power Factor, Voltage, Current and Frequency on a smartphone. Linkage with other Tuya-compatible devices allows automation based on export or import values.
Immediate alerts and the ability to create automation scenes help reduce wasted energy and allow simple control actions triggered by consumption or generation thresholds.
Reliable readings for circuit-level insight - with 200A clamp sensors
Three 200A current clamps measure individual conductors, offering compact, clamp-on installation that fits within typical consumer electrical enclosures. Manufacturer-stated accuracy is ±2% for the reported measurements.
Per-circuit visibility enables targeted energy-saving measures and easier fault spotting, while the clamp design keeps the installation compact within the consumer unit.
