PC4713-W-TY
Three-Phase WiFi Smart Energy Meter
For multi-tenant boards: Tuya 3-phase meter reading 90-277 V per phase, three 750 A CTs, solar export and usage every 15 seconds.
Overview
PC4713-W-TY is the Wi-Fi-only model of the OWON three-phase Tuya range. Three open-type CT clamps go around the incoming conductors — nothing is cut and no supply is interrupted — and consumption, solar export and per-phase values are read in the Tuya App.
It is specified for three-phase four-wire supplies at 90–277 Vac per phase (3×230/400 V AC) and also covers split-phase and single-phase systems. Measurement is bidirectional, so energy drawn from the grid and energy pushed back by a PV array are recorded separately, and CTs from 80 A to 750 A take the same meter from a domestic board to a light-industrial feeder.
Where the PC4713-W-TY Sits in the Range
Every model in the PC4713 family shares one three-phase metering core; the models differ in how the data leaves the meter and whether the meter can switch a load. This is the Wi-Fi-only starting point of the Tuya line. Staying inside that line, Ethernet is added by the PC4713-W-E-TY, the dry-contact relay by the PC4713-W-TY/R, and both together by the PC4713-W-E-TY/R.
Two requirements move a project off this model altogether. A three-phase three-wire or delta service is metered by the PC4713-W-E-TY/3W, which is built for that supply arrangement rather than adapted to it. Keeping data out of a third-party cloud is a change of hardware, not of settings: the equivalent meters are the PC4713 Open API series — PC4713-W over Wi-Fi, PC4713-W-485 over Wi-Fi plus RS485.
PC4713-W-TY Platform and Integration Notes
Reports into the Tuya Cloud, read in the Tuya App. Readings are available live and as history by day, week, month and year. Automation goes beyond display: grid and energy values can be exported to and imported from other Tuya devices, so this meter can act as the trigger for scenes on other equipment in the same account.
Offline storage with automatic re-report. Readings are held locally and re-sent once the network returns, so a dropout does not become a gap in the record.
Notification and language coverage. Alerts are pushed to the App rather than left to be found in a chart, and the App is available in German, French, Spanish and Italian as well as English.
Reactive and apparent power on the home screen, not only active power, so a power-factor problem is visible without opening a report.
Standard Tuya DPs, so Home Assistant keeps working. Standard data points are used wherever possible and custom DPs added only where needed; the standard DPs are what the Home Assistant integration consumes.
PC4713-W-TY Limits and What to Specify Instead
- Three-phase three-wire and delta — not supported by the Tuya four-wire hardware. Specify the PC4713-W-E-TY/3W.
- Relay output — not fitted. The PC4713-W-TY/R and PC4713-W-E-TY/R carry the dry-contact relay.
- Ethernet — not fitted. The PC4713-W-E-TY and PC4713-W-E-TY/R add a 10/100 Mbps port.
- RS485 / Modbus RTU — not offered anywhere in the Tuya range. The PC4713-W-485 Open API meter carries the serial bus.
- A destination other than the Tuya Cloud — this model cannot be pointed at your own server.

Key Benefits
Data Export, Hour by Hour or Day by Day
Per-phase and per-sub-circuit energy can be exported from the App — a single day hour by hour, or a date range day by day, covering up to one year.
Erase Data Without Re-Pairing
Stored data is cleared while the Wi-Fi pairing is kept, so wiping a meter does not mean commissioning it again.
CT Setting You Can Change Yourself
The clamp specification is re-ranged from the App at any time — no service visit to change a CT.
15-Second Reporting
Energy data updates every 15 seconds in the App, so a change in load shows up while you are watching it.
Ideal For
Common deployment scenarios where Three-Phase WiFi Smart Energy Meter delivers the most value.
Solar PV Self-Consumption
Bidirectional measurement tracks generation, grid import/export and home consumption.
Whole-Home Energy Monitoring
Three CT clamps monitor total household consumption on single, split or three-phase supplies.
Commercial Submetering
