Tuya WiFi Smart Energy Meter — 3CT KWH Monitor for Solar, Lighting & Electrical (100–240V)
Take full control of your home or commercial energy consumption with this Tuya WiFi Smart Energy Meter with 3 CT Clamp Sensors. Designed for seamless integration with the Smart Life / Tuya app, this intelligent energy monitor delivers real-time visibility into your voltage, current, power, and kilowatt-hour (kWh) usage — all from your smartphone. Perfect for tracking solar PV systems, electrical panels, lighting circuits, and more.
Key Features
- High-Precision 3-Channel Monitoring: Simultaneously measures voltage, current, power, power factor, and frequency across three independent channels — ideal for three-phase or multi-circuit setups.
- Real-Time App Control: The Tuya / Smart Life app provides live readings for both forward and reverse power flow, making it an excellent companion for solar and photovoltaic (PV) energy systems.
- Detailed Power Statistics: View daily, monthly, and yearly energy totals per channel individually. Percentage-based usage display helps you quickly spot abnormal consumption patterns.
- Smart Automation & Alerts: Set custom power or current threshold values in the app. When thresholds are exceeded, the device triggers automated actions and push notifications directly to your phone.
- Easy DIN Rail Installation: Mounts on a standard 35mm DIN rail — no need to cut or re-route wires. Simply clip the CT sensors around the existing cables for a fast, safe, non-invasive install.
- Bluetooth-Compatible Pairing: Supports Bluetooth-assisted Wi-Fi setup for quick and hassle-free device onboarding.
- Calibration Support: Fine-tune readings by adjusting the percentage offset directly in the app for maximum accuracy.

Frequently Asked Questions
Q: Is this Tuya WiFi energy meter compatible with the Smart Life app?
A: Yes. This smart energy meter is fully compatible with the Tuya and Smart Life apps, available for both iOS and Android. Once paired via Bluetooth-assisted Wi-Fi setup, you can monitor real-time power, current, voltage, power factor, and frequency from anywhere.
Q: Can I use this WiFi KWH monitor with a solar or photovoltaic system?
A: Absolutely. This meter is specifically designed to track both forward (consumption) and reverse (generation) energy flow, making it an ideal monitoring solution for solar PV installations. The app displays daily, monthly, and yearly generation and consumption totals per channel.
Q: How is the CT clamp sensor installed?
A: Installation is non-invasive and straightforward. The device mounts on a standard 35mm DIN rail inside your electrical panel. Simply clip each CT clamp sensor around the existing wire — no cutting or rewiring required. This makes setup safer and faster compared to traditional inline meters.
Q: Does this energy monitor support automation and alerts?
A: Yes. Through the Tuya/Smart Life app, you can set custom power or current threshold values. When readings exceed your defined limits, the device sends push notifications to your smartphone and can trigger automated routines — helping you manage energy use proactively.
