TONGOU Smart Wifi Switch 1P+N AC90-240V 1-50A | Power Monitoring & Recloser | DIN Rail | FCC Certified

Smart energy control for modern spaces

The TONGOU Smart Wifi Switch is designed for reliable, in‑panel control of home and light commercial circuits. With a 1P+N configuration and a wide AC range (AC90-240V), it supports currents up to 50A and is mounted on a standard DIN rail for tidy installations. This device is built to IEC 60947 standards and carries FCC certification for connected environments. Note that it includes protective features such as overcurrent, overvoltage, undervoltage, overpower, and CPU temperature protection, but it does not provide short-circuit protection by itself; pairing with a circuit breaker is recommended.

Real‑time power insight and data export

Monitor real‑time electricity usage, current, voltage, and power of connected devices. The switch records historical power data by hour, day, month, and year, and can export consumption data via email. You can also view the remaining electricity and manage prepaid usage to support broader energy planning.

Local and remote control with flexible automation

When WiFi is available, control is seamless through the Smart Life or Tuya app, with voice control via Alexa or Google Assistant. Even without internet, you can set parameters directly on the LCD display using its three buttons, with password protection to prevent unauthorized changes.

Protection and reliability in one box

Besides standard protections, the device offers three reclosure attempts after overcurrent/overpower events and automatic reclosing after overvoltage/undervoltage events. The closing thresholds provide a clear safeguard for electrical disturbances, helping to minimize risk and downtime.

Design that suits modern installs

The unit supports up to 10 mm² on both the power and load sides, with a color backlit LCD display that is adjustable for brightness. The N pole cannot be disconnected, ensuring stable contact in panel setups while the 3-button local control keeps essential functions accessible even when the network is down.

• Remote control via Smart Life/Tuya app, plus voice control with Alexa and Google Assistant
• Multiple timing options, including schedule, sunrise/sunset, and circulate timers for efficiency
• Real-time and historical power data with export to email

• Compact DIN‑rail mounted, suitable for panel upgrades and new installations
• AC90-240V operation, 1P+N configuration, up to 50A load
• LCD color backlit display with adjustable brightness for quick readings

Whether upgrading a heating circuit, lighting, or other resistive loads, this switch offers a balanced mix of visibility, control, and data that can help you manage energy usage with clarity. It is a possibility for better monitoring and automation, not a guarantee of any particular outcome.
