Main Features：
• Tuya Smart Platform. Supports linking with Amazon Alexa/Google Assistant/Apple Home/Home Assistant to create automation scenarios.
• System integration, seamlessly connecting with other smart devices, third-party servers, energy management platforms, etc. via MQTT API.
• Supports single-phase, split-phase (120/240VAC), and three-phase four-wire (480Y/277VAC) electrical systems.
• Monitors whole-house energy consumption and up to 16 sub-circuits or loads (e.g., lighting circuits, water heaters, air conditioners, EV charging stations, PV inverters, etc.).
• Bidirectional energy measurement: Supports monitoring energy consumption and generation of load lines and the main circuit.
• Real-time monitoring of voltage, current, power factor, active power, and frequency for each phase and sub-circuit.
• View historical data on energy consumption and generation (hourly, daily, weekly, monthly). Supports historical data export (hourly, daily)
• External antenna design enhances signal stability and avoids shielding issues.

FAQ:
Q1: What power systems does the PC341 support?
A: It is compatible with single-phase (120–240VAC), split-phase (120–240VAC, North America), and three-phase 4-wire systems up to 480Y/277VAC.
Q2: How many circuits can it monitor at the same time?
A: In addition to the main line and Phase A/B/C, the PC341 supports monitoring of up to 16 sub-circuits, allowing independent tracking of lighting, outlets, solar inverters, and other loads.
Q3: Does it support bidirectional energy monitoring?
A: Yes. The PC341 supports bidirectional measurement, enabling simultaneous monitoring of both energy consumption and energy production across phases and sub-circuits.
Q4: What is the data reporting interval?
A: The WiFi power meter uploads real-time measurement data every 15 seconds.
