Smart Meters Single Phase Tuya WiFi RJ45 ## 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. ## Specifications | Accuracy | ±1% (Voltmeters) | | --- | --- | | Ammeter Accuracy | 80A CT: ±1% (1-80A), ±2% (0-1A); 120A CT: ±1% (2-120A), ±2% (0-2A); 200A CT: ±1% (2-200A), ±2% (0-2A); 300A CT: ±1% (6-300A), ±2% (2-6A), ±5% (0-2A) | | Voltage | 90~277 Vac 50/60Hz | | Current | 20A~300A (CT dependent) | | Frequency | 50/60Hz | | Power Supply | ## 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. ## Frequently Asked Questions When is the Ethernet port worth paying for? When the meter will sit somewhere Wi-Fi struggles — a metal distribution cabinet, a basement, a plant room — and a network cable is already available or can be pulled to the board. On an open wall with good Wi-Fi reception the PC4711-W-TY does the same job for less. Does the Ethernet port replace Wi-Fi? No, it sits alongside it. Wi-Fi remains the wireless link and handles the BLE-assisted first pairing; the wired port gives the meter a stable path when the wireless signal is poor. A 150 A single-phase commercial board — which CT do I fit? The 200 A clamp (Ø20 mm): a 150 A board sits above the 120 A clamp range. Because the accuracy band is stated per rating, the 200 A clamp holds ±1% from 2 A up, so a small night-time base load is still measured inside ±1%. Does it need a gateway? No. It connects over Wi-Fi or Ethernet by itself. A gateway is only needed for our ZigBee devices. How accurate is it? Voltage ±1%; current ±1% at rated current and ±2% at low current, with the band stated per CT rating rather than as a single figure. Can I export data, and how long is history kept? Yes. Export covers per-phase and per-sub-circuit energy: a single day hour by hour, or a date range day by day, over a one-year window. Can our installers use the App in their own language? Yes. The App is available in German, French, Spanish and Italian as well as English, and alerts are pushed to it rather than left in a chart. Can it be upgraded to the Open API version later? No. Tuya and Open API are different hardware, not firmware variants. ## PC4711 Series — choose the right variant | [PC4711-W](/products/pc4711-w/) | WiFi + open protocol (HTTP / MQTT / Modbus TCP) | | --- | --- | | [PC4711-W-TY](/products/pc4711-w-ty/) | WiFi + Tuya Cloud | | [PC4711-W-TY/R](/products/pc4711-w-ty-r/) | + dry-contact relay (remote on/off) | | PC4711-W-E-TY — this page | + wired Ethernet 10/100 | | [PC4711-W-E-TY/R](/products/pc4711-w-e-ty-r/) | + Ethernet + dry-contact relay | | [PC4711-W-TY/3CT](/products/pc4711-w-ty-3ct/) | + 3 CT channels (three single-phase circuits) | | [PC4711-W-485](/products/pc4711-w-485/) | + RS485 Modbus RTU (BMS / SCADA) | Not sure which variant fits your project?
