Smart Meters Single Phase Tuya WiFi RJ45 ## Overview PC4711-W-E-TY/R (UniClip Pro) is the only single-phase model that combines metering, switching and a choice of network path in one 19 mm module: the dry-contact relay of the /R version and the Ethernet 10/100 Mbps port of the /E version together. The metering core is unchanged - 230 V AC nominal, 90-277 V input range, up to two open-type CTs from 20 A to 300 A, bidirectional measurement and 15-second Tuya reporting - so specifying this model costs the relay and the port, and nothing else. ### PC4711-W-E-TY/R Platform and Integration Notes Automation on measured values. Switching follows the load rather than a manual tap: a Tuya scene can act on a power threshold or a schedule. Offline storage, so a dropout is not a gap in the record. Readings are held locally and re-reported automatically once the network returns. Tuya App, and Home Assistant. The meter is read in the Tuya App and also integrates with Home Assistant, where readings and relay state are both available. Notification, and App languages. Alerts are pushed to the App rather than discovered later, and the App carries German, French, Spanish and Italian in addition to English. ### PC4711-W-E-TY/R Limits and What to Specify Instead - **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** — this model takes up to two CTs. Three single-phase circuits on one device is the PC4711-W-TY/3CT. - **Your own server as the destination** — no Tuya model can be pointed at your own platform; PC4711-W and PC4711-W-485 are the Open API equivalents. ## 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 #### Relay, Ethernet and Wi-Fi Together The only single-phase model carrying all three in one 19 mm DIN module. #### Relay That Drives a Contactor Dry contact rated 3 A resistive / 5 A maximum — a small load directly, or an external contactor for a larger one, status reported instantly. #### Two Open-Type CTs, No Rewiring Up to two split-core CTs from 80 A to 300 A, with bidirectional solar metering on a single-phase circuit. #### Data Export With Day-to-Year History Export from the App with history by day, week, month and year, plus offline storage with automatic re-report. ## Ideal For Common deployment scenarios where Single-Phase WiFi + Ethernet Smart Energy Meter with Relay delivers the most value. #### Cabinet Installations Needing Both Metering, switching and a wired network path in one 19 mm module. #### Plant Rooms Out of Wi-Fi Range Ethernet keeps the meter reachable while the relay controls the load. #### Demand-Based Load Control Switch on a measured threshold, with the wired link carrying the reporting. #### Commercial Single-Phase Boards Sub-metering where the circuit also has to be switched remotely. #### Commissioning Without Site Visits CT re-ranging, data erase and reboot are all reachable from the App. #### Distributor and OEM Programmes Neutral standard units, with branding and packaging available. ## Frequently Asked Questions Why choose this over the PC4711-W-TY/R? Only for the wired network path. If the meter sits in a metal cabinet or a plant room where Wi-Fi is unreliable, the Ethernet port keeps it reachable. If Wi-Fi works at that position, the PC4711-W-TY/R does the same metering and switching for less. What can the relay switch? A dry contact rated 3 A resistive and 5 A maximum with overload protection — a small load directly, or an external contactor for a larger one. Are both the relay and Ethernet active at the same time? Yes. The relay is a local output, the network path is independent of it, and Wi-Fi stays available alongside the wired port. Which single-phase UniClip is the most complete? This one. It is the only single-phase model that combines the relay output with Ethernet and Wi-Fi in one 19 mm module, which is why it is listed as UniClip Pro. Does the App keep the team informed? Yes. Alerts are pushed to the App rather than watched for, and the App covers German, French, Spanish and Italian as well as English. Does it need a gateway? No. Wi-Fi and Ethernet connect directly; a gateway is only needed for ZigBee devices. Which CT ratings are available? Single-phase ratings run from 20 A to 300 A, with the 120 A clamp (Ø16 mm) as the default. The 20 A and 50 A clamps are supported but not held in stock. 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 it be upgraded to the Open API version later? No. Different hardware, not a firmware change. ## 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](/products/pc4711-w-e-ty/) | + wired Ethernet 10/100 | | PC4711-W-E-TY/R — this page | + 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?
