About this item
- Current transformer: CT detection, precise current sensor for up to 50A/230VAC/single-phase, ideal for energy monitoring and load measurement. Suitable for installation in existing switch boxes or any switch panel, requires minimal space.
- Smart WiFi meter: The WiFi electricity meter uses inductive measurement technology, allowing the device cable to be monitored through the inductive hole in the power meter. Real-time energy consumption measurement via the Smart Life/TUYA app.
- APP remote monitoring: (1) Provide a clear interface for monitoring daily, monthly and annual electricity consumption. This allows you to identify which devices are driving up your electricity bill. (2) Reset consumption history and restart monitoring. (3) Energy consumption data is exported to an Excel spreadsheet for collection, management and storage.
- Alarm notification: Push notification is sent when real-time voltage, current or power exceeds the set limits. However, no independent actions are initiated (e.g. shutdown). We also offer graphical representations of voltage, current and power curves for analysis.
- Prepaid top-up: The system also supports prepaid billing, which is particularly advantageous for landlords or tenants who want to track electricity consumption in rental properties.
- Note for solar systems: Please install on the AC side after the inverter. The measured energy corresponds to the sum of the absolute values of the energy fed into and drawn from the grid.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
