PC4713-W-E-TY/R
Three-Phase WiFi + Ethernet Smart Energy Meter with Relay
Meter and switch over one cable — Tuya 3-phase meter with Ethernet and a 3 A dry-contact relay for lighting or HVAC loads.
Overview
PC4713-W-E-TY/R is the most complete model in the OWON three-phase Tuya range: three CT inputs, Wi-Fi, an Ethernet 10/100 Mbps port and a dry-contact relay in the same housing. Metering, switching and network reachability come from one device instead of three.
The relay is rated 3 A resistive and 5 A maximum with overload protection, and its real contact state is reported instantly rather than at the next data cycle. Ethernet and Wi-Fi operate together, so the meter stays reachable in a metal cabinet while Wi-Fi remains available for BLE-assisted setup.
Where the PC4713-W-E-TY/R Sits in the Range
Nothing further can be added within the Tuya line — this is the top of it. The decision below it is which single option to give up: the relay alone is on the PC4713-W-TY/R, the Ethernet port alone on the PC4713-W-E-TY, and neither on the PC4713-W-TY.
The two requirements it cannot meet are the ones that change platform rather than specification. A three-phase three-wire or delta service is metered by the PC4713-W-E-TY/3W, and a project that has to keep data on its own infrastructure rather than in the Tuya Cloud needs the PC4713 Open API series, PC4713-W or PC4713-W-485.
PC4713-W-E-TY/R Platform and Integration Notes
Reports into the Tuya Cloud, read in the Tuya App. Live values and history by day, week, month and year, with grid and energy values exportable to and importable from other Tuya devices — which is how the relay is switched by a scene rather than by hand.
Offline storage with automatic re-report. Readings are buffered locally and re-sent once a network path returns.
Reactive and apparent power on the home screen, not only active power, so a power-factor problem is visible on the first screen.
Standard Tuya DPs keep Home Assistant working. Standard data points are used wherever possible, with custom DPs only where needed.
PC4713-W-E-TY/R Limits and What to Specify Instead
- Three-phase three-wire and delta — specify the PC4713-W-E-TY/3W.
- Switching a three-phase load on the contacts — the dry contact is rated 3 A resistive / 5 A maximum and is intended for a small load or a contactor coil, with the three-phase load switched by that contactor.
- Any destination other than the Tuya Cloud — the PC4713 Open API series is the self-hosted alternative.

Key Benefits
Relay, Ethernet and Wi-Fi in One Module
Measures, switches and stays reachable: Wi-Fi and Ethernet run together, and the relay gives a control output on the same device.
Relay That Can Drive a Contactor
Dry contact rated 3 A resistive / 5 A maximum with overload protection — a small load directly, or an external contactor for a large one.
Data Export, Hour by Hour or Day by Day
Per-phase and per-sub-circuit energy can be exported — a single day hour by hour, or a date range day by day, up to one year.
Notification Alerts to the App
Alerts are pushed rather than discovered later, and the App carries German, French, Spanish and Italian as well as English.
Ideal For
Common deployment scenarios where Three-Phase WiFi + Ethernet Smart Energy Meter with Relay delivers the most value.
Commercial Energy Management
Ethernet stability plus relay control for facility-wide energy management.
Remote Load On/Off Control
Turn loads on/off remotely via the dry-contact relay from the Tuya App.
Solar PV Self-Consumption
Bidirectional measurement tracks generation and consumption across the phases.
Demand Response Programs
Relay control enables load shedding and demand response on three-phase supplies.
Whole-Home Energy Monitoring
Three CT clamps monitor the entire installation on single, split or three-phase supplies.
OEM / ODM Projects
OEM branding and ODM development available for distributors and integrators.
