PC4713 Open Series vs Tuya Series: Which Smart Energy Meter Should You Choose?
What is the difference between the PC4713 Open Series and Tuya Series?
| Factor | PC4713 Open Series | PC4713 Tuya Series |
|---|---|---|
| Models | PC4713-W-485, PC4713-W | PC4713-W-E-TY/R, PC4713-W-E-TY, PC4713-W-TY/R, PC4713-W-TY (plus the PC4713-W-E-TY/3W datasheet) |
| Wi-Fi | 802.11 b/g/n at 2.4 GHz with HTTP / MQTT / Modbus TCP | 802.11 b/g/n at 2.4 GHz, with BLE for pairing |
| Wired connection | RS485 (Modbus RTU) on the PC4713-W-485 | Ethernet 10/100 Mbps on the -E- variants |
| Relay output | Not listed | Dry contact relay (resistive 3 A, max. 5 A) on the /R variants |
| Software | Web browser interface on the device, no app required | Smart Life app with historical data display and export |
| Data path | Report directly to your own cloud server, or read locally without a third-party public cloud | Tuya cloud through the Smart Life app |
| Integration | Open API; Home Assistant (HA platform) integration | Tuya automation scenarios; Home Assistant (HA platform) integration |
| Update rate | Data refresh 50 ms; report time set in the integration | Energy data every 15 seconds |
Protocol documents for HTTP, MQTT and Modbus are provided by OWON sales on request.
Which PC4713 version should I choose?
- Choose the Open Series if you operate your own server, building system or Modbus-based software and do not want to depend on a public cloud.
- Choose the Open Series with RS485 (PC4713-W-485) if you need a wired Modbus RTU connection next to Wi-Fi.
- Choose the Tuya Series if installers or end users will monitor energy in the Smart Life app.
- Choose a Tuya Series model with Ethernet (-E-) if Wi-Fi is weak where the meter is installed.
- Choose a Tuya Series /R model if you also need a dry contact relay controlled from the app.
What do both series have in common?
Both series are DIN rail clamp-on meters that use three current transformers and are compatible with three-phase four-wire, split-phase and single-phase systems. They measure voltage, current, power factor, frequency, active, reactive and apparent power, support bidirectional measurement of energy usage and solar production, store data offline and report it after the network reconnects, and provide data erasure, remote reboot, CT setting and phase sequence error alarm functions. The housing is 19 × 69 × 90 mm and the operating range is -20 to +55 °C.
Does the PC4713 support three-phase three-wire (delta) systems?
The OWON Open Series documents and the PC4713-W-E-TY/R datasheet state that 3-phase 3-wire and delta systems are not supported. The PC4713-W-E-TY/3W datasheet states that 3-phase 3-wire, delta and Y connections are supported. Check the exact model before you design a three-wire installation.

Frequently asked questions
Can the PC4713 work without a cloud?
The PC4713 Open Series datasheet states that real-time data can be reported to your own cloud server or read locally without going through a third-party public cloud, and that the device can be viewed and configured in a web browser without an app.
Does the PC4713 support Home Assistant?
The OWON documents for both the PC4713 Open Series and the Tuya Series state support for HA platform integration.
Which PC4713 variants have a relay?
According to the Tuya Series quick start guide, the PC4713-W-E-TY/R and PC4713-W-TY/R have a built-in relay output. The relay is a dry contact relay rated 3 A resistive, max. 5 A.
