OXT T335 Intelligent Wi‑Fi Energy Controller with 63A Current Rating and Built‑in Power Meter (Tuya)

OXT T335 Intelligent Wi‑Fi Energy Controller with 63A Current Rating and Built‑in Power Meter (Tuya) is a compact DIN-rail device for monitoring and controlling electrical loads up to 63 A. It integrates a power and energy meter with a Wi‑Fi interface compatible with Tuya smart platforms, enabling real-time measurement of voltage, current, power and accumulated energy while providing remote on/off control, scheduling and basic automation for residential and light commercial electrical circuits.

Advantages

The device combines a high current rating with an integrated power meter, allowing a single module to both switch heavy loads and measure energy consumption accurately. Built-in Wi‑Fi and Tuya compatibility simplify remote control and integration with smart home ecosystems. DIN-rail mounting and a compact form factor make installation space-efficient in distribution boards, and the controller supports scheduling and remote on/off to help manage load and optimize energy usage.

Suitable for

• Controlling electric water heaters, boilers and HVAC components up to 63 A
• Load switching and basic automation in residential distribution boards
• Energy monitoring for small commercial circuits and workshops
• Scheduling high-current devices to reduce peak consumption

Key specifications

• Maximum switching current: 63 A
• Integrated power and energy measurement (real-time power, cumulative energy)
• Wi‑Fi connectivity with Tuya cloud/platform compatibility
• DIN-rail mounting for standard distribution boards
• Remote on/off control and scheduling via mobile app or platform

How to use

Install the controller on a DIN-rail inside the electrical distribution board and connect the line and load conductors according to the wiring diagram provided by the manufacturer. After powering the device, use the Tuya-compatible app to connect the controller to the local Wi‑Fi network, complete device setup and configure measurement units if available. Use the app or integrated platform to create schedules, enable remote switching and monitor live voltage, current, power and accumulated energy values.

Usage recommendations

Ensure installation and wiring are performed by a qualified electrician. Verify that connected loads do not exceed the 63 A rating and that wiring, fuses and protective devices are sized appropriately. For accurate energy readings, place the device in a stable network environment and allow time for calibration or cumulative energy measurement to stabilise after initial installation.
