Frequently Asked Questions

Q: Does this 3-phase energy meter work with solar panel systems?

A: Yes — this meter is specifically designed for bidirectional energy measurement, meaning it records both energy drawn from the grid and energy generated by your solar panels. You can monitor solar production and household consumption simultaneously, with usage and production trends available by hour, day, and month in the Tuya Smart or Smart Life app.

Q: What app do I need, and is it compatible with my smartphone?

A: This energy meter works with the Smart Life and Tuya Smart apps, available free on both iOS (Apple App Store) and Android (Google Play Store). Once connected via WiFi, you can view real-time data, set automation rules, and receive push notifications from anywhere.

Q: Can I use this meter on a single-phase electrical system?

A: Absolutely. While this unit is a 3-phase energy meter, it is also fully compatible with single-phase systems. You can use one or all three clamp sensors depending on your installation requirements.

Q: Is professional installation required?

A: The DIN rail mount and clamp-style current sensors make this one of the simpler energy monitoring solutions to install — no need to cut wires, as the clamps simply clip around existing cables. However, because this device is installed inside an electrical switchboard, we always recommend having a licensed electrician perform or oversee the installation to ensure safety and compliance with local regulations.
