PC4711-W-E-TY
Single-Phase WiFi + Ethernet Smart Energy Meter
UniClip with a cable: single-phase Tuya meter on WiFi with an Ethernet 10/100 Mbps path for weak-signal cabinets, two 300 A CTs, 15-second reporting.
Overview
PC4711-W-E-TY answers one site problem: the meter has to live where the wireless signal does not reach. It is the PC4711-W-TY metering core with an Ethernet 10/100 Mbps port added, so data travels on a cable while Wi-Fi stays available for the BLE-assisted setup.
The rest is the single-phase UniClip platform: 230 V AC nominal, a 90-277 V input range, up to two open-type CTs from 20 A to 300 A, bidirectional energy measurement and 15-second reporting into the Tuya App. No relay - this model is about the signal, not switching.
PC4711-W-E-TY Platform and Integration Notes
Offline storage, so a dropout is not a gap in the record. Readings are held locally and re-reported automatically once the network returns — which covers the wired link being down as well as the wireless one.
Export and history are the change from the previous generation. The free Tuya app on earlier models kept 7 days of history and could not export hourly data; this meter exports, with history by day, week, month and year.
CT setting, data erase and remote reboot from the App. A clamp can be re-ranged or a record cleared without a site visit.
Tuya App, and Home Assistant. The App is the primary front end for readings and history, and the meter also integrates with Home Assistant.
Notification, and languages for the installer. Notifications reach the App through the platform rather than being checked for, and the App is available in German, French, Spanish and Italian as well as English.
Bidirectional by default. Consumption and solar export are measured in one device.
PC4711-W-E-TY Limits and What to Specify Instead
- Relay output — not fitted. The PC4711-W-E-TY/R carries both this Ethernet port and the dry-contact relay.
- Three-phase, split-phase or 3P3W supplies — a single-phase meter; three-phase services need the PC4713 range, and a 3P3W or delta supply specifically needs the PC4713-W-E-TY/3W.
- A third metering channel — up to two CTs here; three single-phase circuits need the PC4711-W-TY/3CT.
- Your own server as the destination — PC4711-W or PC4711-W-485 from the Open API range.

Key Benefits
Ethernet 10/100 Alongside Wi-Fi
A wired path for the cabinet, basement or plant room where the wireless signal does not reach, with Wi-Fi still available.
Two Open-Type CTs, No Rewiring
Up to two split-core CTs from 80 A to 300 A clip around the existing cable, with no supply interruption.
Data Export With Day-to-Year History
Export from the App with history by day, week, month and year, plus offline storage that re-reports automatically after a dropout.
Accurate Where It Is Hard
Voltage ±1%, current ±1% at rated and ±2% at low current, with the band stated per CT rating.
Ideal For
Common deployment scenarios where Single-Phase WiFi + Ethernet Smart Energy Meter delivers the most value.
Metal Cabinets and Basements
The wired Ethernet path keeps the meter reachable where a wireless signal does not.
Sites with Existing Cabling
Where a network drop already reaches the board, the meter uses it instead of relying on Wi-Fi.
Commercial Submetering
Single-phase circuits metered where the reading is taken remotely rather than at the board.
Solar Self-Consumption
Bidirectional measurement shows production and consumption on the same circuit.
Commissioning Without Signal Hunting
Wi-Fi handles the BLE-assisted first pairing; Ethernet carries the ongoing reporting.
Distributor and OEM Programmes
Neutral standard units, with branding and packaging available.
